The phosphate solubilizing properties of Lysinibacillus macroides ST-30, Pseudomonas pelleroniana N-26, and Bacillus cereus ST-6 were tested for the chickpea crop of the Tarai region of Uttarakhand. These microbially inoculated plants have shown significant (p > 0.05) improvement in the plant health and crop health parameters, viz., root length, shoot length, fresh weight, dry weight, nodule number, nodule fresh weight, nodule dry weight, chlorophyll content, and nitrate reductase. The highest shoot length (46.10 cm) and chlorophyll content (0.57 mg g-1 fresh weight) were observed in ST-30 at 75 DAS with 20 kg P2O5/ha. Similarly, for plant P content, an increase of 90.12% over control was recorded in the same treatment. Treatments consisting of Lysinibacillus macroides ST-30 along with 20 kg/ha P2O5 were found to be most suitable as phosphatic fertilizer. Conclusively, sustainable agriculture practices in the Tarai as well as the field region may be developed based on a strategy of exploring microbial inoculants from the pristine region of the Western Himalayas. The presence and abundance of bacterial inoculants were confirmed through qRT-PCT. We conclude that the effective plant growth-promoting bacterium Lysinibacillus macroides ST-30 broadens the spectrum of phosphate solubilizers available for field applications and might be used together with 20 Kg/ha P2O5.

ABSTRACT The leguminous chickpea is a good source of protein, but its yield potential is frequently constrained by biotic stresses, primarily Helicoverpa armigera, a major havoc for cultivation of the crop. To develop host plant resistance for minimizing the losses due to the pod borer, five kabuli parents with desired traits for pod borer tolerance were crossed in diallel mating design to produce 10 crosses which were analysed for traits related to pod borer and nutrition. Based on correlation studies, trichome density was found positively correlated with phenol content, but both the traits were negatively associated with number of damaged seeds. Therefore, the tolerant genotypes were identified on the basis of phenol content, trichome density, number of damaged seeds and field rating. Among parents ICC 12197 was found superior in terms of yield and borer tolerance features with an intermediate pest resistance susceptible rating in addition to higher Fe content. However, significant sca effects for higher phenol content and seed yield in ICC 11764 × ICC 14190 were recorded with reduced number of damaged seeds in addition to higher Fe and Zn content. It was observed that the specific combination involved good and poor combiners for each trait. The same cross also showed significant standard heterosis in desirable direction for phenol content, trichome density, number of damaged seeds and seed yield. Additionally, the ratio of σ2 GCA to σ2 SCA revealed nonadditive gene action in controlling the expression of phenol content, trichome density, number of damaged seeds and Fe and Zn content. Thus, breeder may focus efforts on desirable cross utilizing selection in further segregating generations for higher phenol content, trichome density and Fe and Zn content in addition to yield‐related traits while lesser number of damaged seeds per plant to concentrate for development of pod borer resilient high yielding kabuli genotypes to combat micronutrient deficiency.

• Late sown chickpea faces heat stress that drastically reduces grain yield in the NE plains of India. • Chickpea genotypes respond differently to late sown associated heat stress. • 'Pusa 3043′ and 'DBGC 4′ showed least yield reductions under late sown condition. • Both the genotypes mitigated heat stress by accumulating more ascorbic acid than the sensitive ones. Post rice cultivation, chickpea (Cicer arietinum L.) sowing is very often delayed due to late harvesting of preceding rice crop in the north-east plains of India. This exposes the late sown chickpea to heat stress, which substantially reduces the chickpea yield. The present study aimed to understand the most important physiological basis for genotypic response to yield differences in chickpea. Two trials, each one comprising five released cultivars and five advance breeding lines of chickpea, were conducted under timely sown and late sown conditions consecutively for two years (2018–19 & 2019–20). Three genotypes 'DBGC 1′, 'DBGC 3′ and 'Pusa 547′ were identified as high yielders under timely sown condition, whereas two other genotypes 'Pusa 3043′ and 'DBGC 4′ excelled all others, and showed least yield reductions under late sown condition. Yield under late sown condition showed significant negative and positive correlations respectively with days to flowering (50 %), maturity duration and 100 seed weight, and per day yield, yield/plant, harvest index and pods/plant. Among physiological characters, carotenoids and ascorbic acid content had very strong and positive associations with yield under late sown condition. Path coefficient analysis differentiated ascorbic acid further from other physiological attributes as it showed high and direct positive effect on yield. Significantly enhanced accumulation of ascorbic acid precisely explained better yield performance of chickpea genotypes 'Pusa 3043′ and 'DBGC 4′ under late sown condition. [ABSTRACT FROM AUTHOR]

• Efficacy of cyanobacteria-based/biofilms and their formulations as seed coating evaluated. • Storability in terms of seed germination and vigor tested in two chickpea varieties. • Cyanobacterial seed coating led to significant enhancement in vigor indices. • Anabaena laxa and cyanobacterial consortium were the top performers. • Field performance needs to be undertaken to validate the beneficial impact of coated seeds. The efficacy of selected cyanobacterial formulations as seed coating for improving seed germination, vigor, and storability of two chickpea varieties Pusa 3062 (Desi) and Pusa 3022 (Kabuli) was evaluated. The application of microbial formulations through seed coating, and recommended chemical treatment (± RST) exhibited a positive impact on seed storability (upto 6 months). This was evident from improvement by 2–4 % higher seed germination, and 25–57 % higher vigour indices, even after 6 months storage; with notable interactions between varieties and treatment methods. Highest percent germination in Desi and Kabuli chickpea varieties after 6 months of storage was observed in An-Rh biofilm + RST (99.25) and BF1- 4 cyanobacterial consortium + RST (95 %), respectively. Percent decrease in germination over the storage period was greater in Kabuli, and among all treatments, across both varieties, in control. Viability studies of the seed coatings with cyanobacteria, using chlorophyll, microscopy and growth as indices, further supported their longevity and beneficial impact upto 6 months storage. Out of all treatments, Anabaena laxa followed closely by BF1- 4 Cyanobacterial consortium + RST were superior. The mean effect of treatments was influenced significantly by variety and their interactions with the period of storage (0, 3, 6 months). PCA validated the significant influence of treatments, with vigor indices as dominant variables. Seed coating with these cyanobacterial formulations can be recommended as an effective strategy to enhance crop vigor as well as seed storability, along with testing the field performance to further validate the beneficial impact of coated seeds.

Summary: In this study, nano‐reduction of dietary fibre using ball milling and its influence on physicochemical, structural and microbial properties were studied. Dynamic light scattering confirmed the average particle size of 382 nm for nano‐reduced dietary fibre. FTIR represents the peak differences between native and nano‐reduced dietary fibre. XRD displayed the polycrystalline nature of nano‐reduced dietary fibre. The physicochemical properties including WHC, OHC and swelling capacity increased significantly (P < 0.05) upon nano‐reduction of dietary fibre whereas moisture content was found to decrease significantly. Furthermore, the antimicrobial activity of nano‐reduced dietary fibre against Escheria coli and Bacillus Cerus was enhanced. The improved physicochemical, morphological and microbial properties of nano‐reduced dietary fibre can pave the way in food industries for the formulation of functional foods and also as a packaging material with improved antimicrobial properties.

Water deficit stress is one of the key determinants causing crop yield losses globally. The present study was conducted to effectively screen Desi chickpea genotypes based on early dehydration tolerance-related traits as a tool for further evaluation in field experiments. Sixty-four genotypes of Desi chickpea were assessed under progressive water deficit stress, resulting in high variability in early growth characteristics and traits. The clustering analysis with UPGMA, separated the genotypes into three major groups, in accordance with biplot analysis grouping. The highest root length density was observed in the MCC438 genotype with an 18.6-fold increase compared to MCC884 which showed the lowest root length density among all analyzed chickpea genotypes. The genotypes MCC32 and MCC539 produced the higher shoot and root dry weight, while MCC884 showed the lowest value (with 12- and 32.5-fold differences, respectively). Ten genotypes showed differences in terms of their overall response to the water deficiency stress, including eight tolerant genotypes (MCC320, MCC418, MCC425, MCC438, MCC539, MCC540, MCC560, MCC576) and two susceptible ones (MCC433 and MCC897), were selected for further investigation of various growth and physio-biochemical traits based on drought response indices. A clear distinction was observed among ten analyzed genotypes for some physio-biochemical traits, indicating their tolerant responses to drought stress. Drought-tolerant candidate genotypes showed higher indices of seedling growth parameters, proline content, RWC, membrane stability, and root-to-shoot ratio in comparison to drought-susceptible candidate genotypes. The genotypes MCC425, MCC438, MCC418, and MCC539 were found more drought tolerant in the seedling stages, whereas genotype MCC433 was more sensitive. These results were consistent with what was obtained in our preliminary study. However, these results should be addressed further in the field conditions. [ABSTRACT FROM AUTHOR]

Acetochlor, as a commonly used pre‐emergent herbicide, can be toxic to crops and affect production if used improperly. However, the toxic mechanism of acetochlor on plants is not fully understood. The present study used a combination of transcriptomic analysis and physiological measurements to investigate the effects of short‐term (15‐day) exposure to different concentrations of acetochlor (1, 10, 20 mg/kg) on the morphology, physiology, and transcriptional levels of pea seedlings, aiming to elucidate the toxic response and resistance mechanisms in pea seedlings under herbicide stress. The results showed that the toxicity of acetochlor to pea seedlings was dose‐dependent, manifested as dwarfing and stem base browning with increasing concentrations, especially at 10 mg/kg and above. Analysis of the antioxidant system showed that from the 1 mg/kg treatment, malondialdehyde, superoxide dismutase, peroxidase, and glutathione peroxidase in peas increased with increasing concentrations of acetochlor, indicating oxidative damage. Analysis of the glutathione (GSH) metabolism system showed that under 10 mg/kg treatment, the GSH content of pea plants significantly increased, and GSH transferase activity and gene expression were significantly induced, indicating a detoxification response in plants. Transcriptomic analysis showed that after acetochlor treatment, differentially expressed genes in peas were significantly enriched in the phenylpropane metabolic pathway, and the levels of key metabolites (flavonoids and lignin) were increased. In addition, we found that acetochlor‐induced dwarfing of pea seedlings may be related to gibberellin signal transduction. Environ Toxicol Chem 2024;43:2005–2019. © 2024 SETAC [ABSTRACT FROM AUTHOR]

The fatty acid profiling in chickpea remains unexplored and offers relevant knowledge for crop improvement program. In the present work, the metabolite approach has been utilized with mass spectral analysis to metabolite changes in twelve varieties of kabuli as well as desi cultivars (twenty four totals) for fatty acid profiling. The total oil was extracted and found to be higher in all cultivars of kabuli chickpea (3.6–5.3%) as compared to all desi chickpea (3.2–4.6%) cultivars. However, no difference in the refractive indices of desi (1.4755–1.4773) and kabuli (1.4739–1.476) cultivars has been observed. Polyunsaturated fatty acids (PUFAs) were reported to be predominant (kabuli; 50–68.6%, desi; 61.5–72.5%) and monounsaturated (MUFA) (kabuli; 19.9–38.4%, desi; 16.7–26.4%) and saturated fatty acids (SFA) (kabuli; 11–14.9%, desi; 10–11.9%) were relatively low in the oil of all selected cultivars. Among fatty acids, linoleic acid (C18:2), followed by oleic acid (C18:1), was most prevalent in all selected chickpea cultivars. The volatile organic compounds, 9,12-octadecadienoic acid, 9-octadecenoic acid, and hexadecanoic acid have also been detected comparatively high. Similarly, oil contents also detected terpenoids including b-tocopherol, fucosterol, stigmasterol, and stigmata-5, 22-dien-3-ol. This work could offer comprehensive understanding of fatty acid composition in chickpea that could be used further for crop improvement to assess their nutritional importance in human diet and help to draft strategy for improving self-life during storage of flour of chickpea. This key insight of this work could be further harness to identify potential biochemical biomarkers for improving fatty acid content in chickpea seeds for crop improvement. [ABSTRACT FROM AUTHOR]

Summary The growing global population has increased the protein needs and the combination of animal with plant proteins can be an effective strategy to meet future protein demand. This study aimed to investigate the impact of pH between 6.2 and 7.0 on the thermal stability of a 1:1 mixture of chickpea protein concentrate (CPC) and whey protein isolate (WPI), and their respective control. After heat treatment, CPC:WPI mixture showed an increase in viscosity (from 20.5 mPa.s at pH 7.0 to 110.8 mPa.s at pH 6.2, respectively), and particle size (from 5.7 to 56.5 μm at pH 7.0 and 6.2, respectively). The physical stability of the heat‐treated CPC:WPI mixture decreased, as the sediment increased from 3.3 mm at pH 7.0 to 7.8 mm at pH 6.2. This study highlighted the enhanced thermal stability of CPC:WPI at pHs closer to neutrality and offers valuable insights for the formulation of innovative plant protein‐enriched food.

Introduction: Ascochyta blight (AB) caused by the necrotrophic fungus Ascochyta rabiei is one of the most significant diseases that limit the production of chickpea. Understanding the metabolic mechanisms underlying chickpea-A.rabiei interactions will provide important clues to develop novel approaches to manage this disease. Methods: We performed metabolite profiling of the aerial tissue (leaf and stem) of two chickpea accessions comprising a moderately resistant breeding line (CICA1841) and a highly susceptible cultivar (Kyabra) in response to one of the highly aggressive Australian A. rabiei isolates TR9571 via non-targeted metabolomics analysis using liquid chromatography-mass spectrometry. Results: The results revealed resistance and susceptibility-associated constitutive metabolites for example the moderately resistant breeding line had a higher mass abundance of ferulic acid while the levels of catechins, phthalic acid, and nicotinic acid were high in the susceptible cultivar. Further, the host-pathogen interaction resulted in the altered levels of various metabolites (induced and suppressed), especially in the susceptible cultivar revealing a possible reason for susceptibility against A.r abiei. Noticeably, themass abundance of salicylic acid was induced in the aerial tissue of the susceptible cultivar after fungus colonization, while methyl jasmonate (MeJA) was suppressed, elucidating the key role of phytohormones in chickpea-A. rabiei interaction. Many differential metabolites in flavonoid biosynthesis, phenylalanine, Aminoacyl-tRNA biosynthesis, pentose and glucuronate interconversions, arginine biosynthesis, valine, leucine, and isoleucine biosynthesis, and alanine, aspartate, and glutamate metabolism pathways were upand down-regulated showing the involvement of these metabolic pathways in chickpea-A. rabiei interaction. Discussion: Taken together, this study highlights the chickpea -- A. rabiei interaction at a metabolite level and shows how A. rabiei differentially alters the metabolite profile ofmoderately resistant and susceptible chickpea accessions and is probably exploiting the chickpea defense pathways in its favour.

Edible insects have been evaluated as an alternative and sustainable source of protein because of their nutritive and functional properties for humans and domestic animals. The objective of this study was to assess the use of chemometric [principal component analysis (PCA) and partial least squares (PLS)] combined with Rapid Visco Analyser (RVA) profiles to evaluate the addition of cricket powder (CKP) to chickpea (CPF) and flaxseed (FxF) flours. The results of this study showed that the addition of CKP powder to both CPF and FxF flours affects the pasting properties of the samples; in particular, a reduction in the peak (PV) and final viscosity (FV) was observed. The use of chemometric data techniques such as PCA and PLS regression allowed for a better interpretation of the RVA profiles. Both PCA and PLS regression allowed to qualitative and quantitatively identify the addition level of CKP powder to CPF and FxF flour samples. Differences in the PLS loadings associated with the RVA profile due to the addition of cricket powder were observed. The development of these methodologies will provide researchers and the food industry with better tools to both improve and monitor the quality of ingredients with functional properties as well as to further understand the use of insects as alternative sources of protein.

Resistant starch (RS) is a fraction of starch not digested and absorbed in the small intestine, and it is fermented by the intestinal microbiota in the colon, thereby influencing many health benefits. Legumes such as beans, lentils, and chickpeas are rich in fermentable dietary fiber, and RS can be included in this fiber group. These legumes are not considered a "typical" source of starch and have not been extensively studied as a source of RS. There are still insufficient data on modern non-thermal methods like high-pressure processing (HPP) and combining this method with refrigerated storage. The study aimed to investigate and compare the effects of HPP and HPP combined with refrigerated storage on the RS content of legumes, particularly white beans, green lentils, and chickpeas. Different pressure levels and processing times were used to evaluate changes in RS content and to assess the total fiber content and fiber fraction of the tested legumes. Our study showed that the increase in pressure and pressurization time affected changes in the RS content of the examined legumes. Furthermore, the cooling process of previously pressurized samples resulted in a significant increase in RS content. [ABSTRACT FROM AUTHOR]

The sustainable management of large amounts of fly ash (FA) is a concern for researchers, and we aim to determine the FA application in plant development and nematicidal activity in the current study. A pot study is therefore performed to assess the effects of adding different, FA-concentrations to soil (w/w) on the infection of chickpea plants with the root-knot nematode Meloidogyne incognita. Sequence characteristic amplified region (SCAR) and internal transcribed spacer (ITS) region-based-markers were used to molecularly confirm M. incognita. With better plant growth and chickpea yield performance, FA enhanced the nutritious components of the soil. When compared with untreated, uninoculated control (UUC) plants, the inoculation of M. incognita dramatically reduced chickpea plant growth, yield biomass, and metabolism. The findings showed that the potential of FA to lessen the root-knot nematode illness in respect of galls, egg-masses, and reproductive attributes may be used to explain the mitigating effect of FA. Fascinatingly, compared with the untreated, inoculated control (UIC) plants, the FA treatment, primarily at 20%, considerably (p ≤ 0.05) boosted plant growth, yield biomass, and pigment content. Additionally, when the amounts of FA rose, the activity of antioxidants like superoxide dismutase-SOD, catalase-CAT, and peroxidase-POX as well as osmo-protectants like proline gradually increased. Therefore, our findings imply that 20% FA can be successfully applied as a potential strategy to increase biomass yield and plant growth while simultaneously reducing M. incognita infection in chickpea plants.

Background: Chickpea is a key pulse crop grown in the spring in dryland regions. The cold resistance potential of chickpeas allows for the development of genotypes with varying sowing dates to take advantage of autumn and winter rainfall, particularly in dryland regions. In this study, we assessed grain yield, plant height, 100-seed weight, days to maturity, and days to flowering of 17 chickpea genotypes in five autumn-sown dryland regions from 2019 to 2021. Additionally, the response of selected chickpea genotypes to cold stress was examined at temperatures of -4 °C, 4 °C, and 22 °C by analyzing biochemical enzymes. Results: Mixed linear model of ANOVA revealed a significant genotype × environment interaction for all traits measured, indicating varying reactions of genotypes across test environments. This study reported low estimates of broad-sense heritability for days to flowering (0.34), days to maturity (0.13), and grain yield (0.08). Plant height and seed weight exhibited the highest heritability, with genotypic selection accuracies of 0.73 and 0.92, respectively. Moreover, partial least square regression highlighted the impactful role of rainfall during all months except of October, November, and February on grain yield and its interaction with environments in autumn-planted chickpeas. Among the genotypes studied, G9, G10, and G17 emerged as superior based on stability parameters and grain yield. In particular, genotype G9 stood out as a promising genotype for dryland regions, considering both MTSI and genotype by yield*trait aproaches. The cold assay indicated that − 4 °C is crucial for distinguishing between susceptible and resistant genotypes. The results showed the important role of the enzymes CAT and GPX in contributing to the cold tolerance of genotype G9 in autumn-sown chickpeas. Conclusions: Significant G×E for agro-morphological traits of chickpea shows prerequisite for multi-trial analysis. Chickpea's direct root system cause that monthly rainfall during plant establishment has no critical role in its yield interaction with dryland environment. Considering the importance of agro-morphological traits and their direct and indirect effects on grain yield, the utilization of multiple-trait stability approches is propose. Evaluation of chickpea germplasm reaction against cold stress is necessary for autumn-sowing. Finally, autumn sowing of genotype FLIP 10–128 C in dryland conditions can led to significant crop performance. [ABSTRACT FROM AUTHOR]

Morphological plasticity may be induced by altering host plants and commonly it is sex‐specific in phytophagous insects. It is hypothesized that stress in insects caused by a host shift leads to morphological changes and developmental destabilization, which may be identified by fluctuating asymmetry. We performed reciprocal transplant experiments in eight replicated populations of the seed beetle Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae, Bruchinae) adapted to common bean (Phaseolus vulgaris L., Fabaceae) as its ancestral host and chickpea (Cicer arietinum L., Fabaceae) as a suboptimal host. Using methods of geometric morphometrics we assessed the effects of the short‐ and long‐term host shift on size and shape variation of beetles of both sexes. We also tested the hypothesis that fluctuating asymmetry is lower when the beetles develop within seeds of the ancestral host. Our results showed that females respond more plastically related to their body size and shape of the abdomen, particularly during a short‐term host shift, suggesting that females have a greater importance in maintaining the population on a new host. The level of fluctuating asymmetry is lowest in males that have evolved for generations on bean indicating that they have the most canalized development, so we suggested that symmetry in A. obtectus is maintained by sexual selection. Even if the beetles are adapted to a suboptimal host over many generations, they stabilize their development after returning to the ancestral host. Our work indicates that host shifts may change morphological aspects of the beetles in a sex‐specific manner and consequently influence their developmental trajectories. [ABSTRACT FROM AUTHOR]

• Nanosilicon was synthesized and characterized for size, shape, stability and functional group analysis. • Metabolomics elucidated differential metabolites of PEG-induced water stress and nanosilicon-treated leaves. • Volcano plot demonstrated differential metabolites recognized significantly in tolerant vs. susceptible group. • Enrichment analysis explains drought-responsive metabolites and novel pathways inclined by nanosilicon. Chickpea (Cicer arietinum L.) is a crucial agricultural crop, facing challenges in yield due to environmental stresses, particularly drought. The potential of nanosilicon (NS) in improving drought tolerance in crops remains unclear. This study efforts on synthesizing and characterizing silicon nanoparticles using sodium silicate, examining properties such as size, shape, stability, and functional groups before assessing their potential biological effects. Two chickpea varieties, drought-tolerant (GJG-6) and drought-susceptible (GJG-3), were selected based on previous research exploring biochemical and physiological changes under polyethylene glycol (PEG)-induced osmotic stress. Gas chromatography and mass spectrometry were employed to elucidate the metabolomic profile of chickpea leaves under PEG-induced osmotic stress, with and without NS treatment, at 23 days after sowing. Heatmap analysis depicted the intensity gradient of identified metabolites induced by NS treatment under osmotic stress. Fold change and volcano plot analyses revealed significantly differential metabolites between tolerant (T) and susceptible (S) groups. Metabolites such as l -tryptophan, d -fucitol, beta- d -(+) talopyranose, alloxanic acid, and azelaic acid were significantly upregulated in the tolerant group (T/S). Remarkably, metabolites like oxalic acid, 5-methyluridine, l -histidine, lactic acid, l -asparagine, and mannonic acid exhibited higher fold changes in the NS-treated tolerant variety compared to the susceptible one under drought influence (T_PEGNS/S_PEGNS). NS-treated tolerant variety revealed vital drought-responsive metabolites like l -asparagine, behenic acid, alanine, stearic acid, and d -mannose. This study unveils novel metabolites responsive to drought stress and induced by NS treatments, emphasizing their roles in antioxidants and signal transduction pathways that mitigate the effects of drought in chickpea.

Chickpea is a staple crop for many nations worldwide. Modeling genotype-by-environment interactions and assessing the genotype's ability to contribute adaptive alleles are crucial for chickpea breeding. In this study, we evaluated 12 agronomically important traits of 159 accessions from the N.I. Vavilov All Russian Institute for Plant Genetic Resources collection. These included 145 landraces and 13 cultivars grown in different climatic conditions in Kuban (45°18′ N and 40°52′ E) in both 2016 and 2022, as well as in Astrakhan (46°06′ N and 48°04′ E) in 2022. Using the IIIVmrMLM model in multi-environmental mode, we identified 161 quantitative trait nucleotides (QTNs) with stable genetic effects across different environments. Furthermore, we have observed 254 QTN-by-environment interactions with distinct environment-specific effects. Notably, five of these interactions manifested large effects, with R2 values exceeding 10%, while the highest R2 value for stable QTNs was 4.7%. Within the protein-coding genes and their 1 Kb flanking regions, we have discerned 22 QTNs and 45 QTN-by-environment interactions, most likely tagging the candidate causal genes. The landraces obtained from the N.I Vavilov All Russian Institute for Plant Genetic Resources collection exhibit numerous favorable alleles at quantitative trait nucleotide loci, showing stable effects in the Kuban and Astrakhan regions. Additionally, they possessed a significantly higher number of Kuban-specific favorable alleles of the QTN-by-environment interaction loci compared to the Astrakhan-specific ones. The environment-specific alleles found at the QTN-by-environment interaction loci have the potential to enhance chickpea adaptation to specific climatic conditions. [ABSTRACT FROM AUTHOR]

Chickpeas (Cicer arietinum L.) are an important legume crop known for their rich nutrient content, including proteins, carbohydrates, and minerals. Thus, they are enjoyed by people worldwide. In recent years, the production scale of chickpeas has been growing gradually. The planting area of chickpeas represents roughly 35–36% of the total planting area, and the output of the beans is roughly 47–48%. However, the growth and development process of chickpeas is limited by a number of factors, including high temperature, drought, salt stress, and so forth. In particular, high temperatures can reduce the germination rate, photosynthesis, seed setting rate, and filling rate of chickpeas, restricting seed germination, plant growth, and reproductive growth. These changes lead to a decrease in the yield and quality of the crop. Heat shock proteins (HSPs) are small proteins that play an important role in plant defense against abiotic stress. Therefore, in the present study, HSP20 gene family members were identified based on the whole-genome data of chickpeas, and their chromosomal positions, evolutionary relationships, promoter cis-acting elements, and tissue-specific expression patterns were predicted. Subsequently, qRT-PCR was used to detect and analyze the expression characteristics of HSP20 genes under different temperature stress conditions. Ultimately, we identified twenty-one HSP20 genes distributed on seven chromosomes, and their gene family members were found to be relatively conserved, belonging to ten subfamilies. We also found that CaHSP20 promoter regions have many cis-acting elements related to growth and development, hormones, and stress responses. In addition, under high-temperature stress, the relative expression of CaHSP20-17, CaHSP20-20, CaHSP20-7, CaHSP20-3, and CaHSP20-12 increased hundreds or even thousands of times as the temperature increased from 25 °C to 42 °C. Among them, excluding CaHSP20-5, the other five genes all contain 1-2 ABA cis-regulatory elements. This finding indicates that CaHSP20s are involved in the growth and development of chickpeas under heat stress, and the mechanisms of their responses to high-temperature stress may be related to hormone regulation. The results of the present study lay the foundation for exploring HSP20 gene family resources and the molecular mechanisms of heat resistance in chickpeas. Our results can also provide a theoretical basis for breeding high-temperature-resistant chickpea varieties and provide valuable information for the sustainable development of the global chickpea industry.

The aim of this study was to investigate the modification of mechanical, rheological, and sensory properties of chickpea pastes and gels by incorporating other ingredients (olive oil or quinoa flour), to develop plant‐based alternatives that meet consumer demands for healthy, natural, and enjoyable food products. The pastes and gels were made with different amounts of chickpea flour (9% and 12%, respectively). For each product, a first set of products with different oil content and a second set with quinoa flour (either added or replaced) were produced. The viscoelastic properties of the pastes and the mechanical properties of the gels were measured. Sensory evaluation and preference assessment were carried out with 100 participants using ranking tests. The study found remarkable differences in rheological, mechanical, and sensory properties of chickpea products upon the inclusion of oil and quinoa flour. The addition of oil increased the viscosity and decreased the elastic contribution to the viscoelasticity of the pastes, while it improved the firmness and plasticity in gels. It also increased the creaminess and preference of both pastes and gels. Replacing chickpea with quinoa flour resulted in less viscous pastes and gels with less firmness and more plasticity. In terms of sensory properties, the use of quinoa as a replacement ingredient resulted in less lumpiness in the chickpea paste and less consistency and more creaminess in both the pastes and gels, which had a positive effect on preference. The addition of quinoa increased the viscosity of pastes and the firmness and stiffness of gels. It increased the consistency and creaminess of both pastes and gels. Quinoa flour and/or olive oil are suitable ingredients in the formulation of chickpea‐based products. They contribute to the structure of the system, providing different textural properties that improve acceptance. [ABSTRACT FROM AUTHOR]

There is a need for increasing cropping intensity in South Asia including India to ensure food security of burgeoning population. Accordingly, increasing cropping intensity in rainfed rice fallows can be a futuristic strategy. Identification of suitable cultivar and exploration of genetic variability of specific crops/traits are imperative for genetic improvement, drought resistance and yield gain in rice fallows. We evaluated the morphophysiological, yield traits and stability of 15 chickpea genotypes in randomised complete block design for three consecutive years on a drought‐prone rainfed condition of Fluvisol in Kanpur, India. Among genotypes, 'IPC 2014‐55', 'IPC 2015‐44' and 'IPC 2011‐92' had 2%–10% higher relative water content (RWC) over 'ICC‐92944' (check cultivar). These genotypes did not differ for total chlorophyll content, root dry weight and nodule dry weight with 'ICC‐92944' and 'KWR 108' (wider adaptable cultivar of the region). The nitrogen balance index was higher in 'IPC 2011‐92', 'IPC 2014‐88' and 'IPC 2014‐55' by 5%–44% over check cultivar (p < 0.05). The membrane stability index was higher for 'IPC 2014‐55' (30%, p < 0.05) and 'IPC 2011‐92' (17%, p < 0.05) than 'ICC‐92944'. 'IPC 2011‐92', 'IPC 2014‐88' and 'IPC 2014‐55' (3 years mean) had 3%–24% higher plant dry weight than 'ICC‐92944'. Notably, 'IPC 2014‐55', 'IPC 2015‐44', 'IPC 2014‐88' and 'IPC 2011‐92' had higher yield attributes such as pods plant−1 by 9%, grain weight plant−1 by 13% and 100‐seed weight by 3% than 'ICC‐92944' and 'KWR 108' (mean of years). These genotypes had higher mean seed yield than 'ICC‐92944' by 23%–42% and 'KWR 108' by 7%–23% (p < 0.05). The yield of 'IPC 2014‐55', 'IPC 2015‐44', 'IPC 2014‐88' and 'IPC 2011‐92' were stable over years across variable soil and environmental condition as indicated by the genotype × year biplot. Membrane stability index, pods plant−1 and 100‐seed weight were the determinants for increased seed yield of chickpea under drought‐prone condition. Evidently, genotype 'IPC 2014‐55', 'IPC 2015‐44', 'IPC 2014‐88' and 'IPC 2011‐92' were better under rainfed rice fallows. These genotypes could be tested under specific drought condition for developing varieties and promoted in rice fallows of South Asia for yield advantage and drought resistance.

Chickpeas are well adapted to rainfed conditions, but a lack of moisture during the reproductive phase can result in lower pod setting and ultimately reduced grain yield. The exact reasons for this reduction are not fully understood, partly because of the lack of information on soil moisture content (SMC) and water use during podding. This study aimed to address this knowledge gap by quantifying the impact of gradual drought on various yield components of desi‐type genotypes using the fraction of transpirable soil water (FTSW) method. Two water treatments were applied at the start of anthesis: well‐watered (WW) and drought‐stressed (DS). The WW was maintained at 24% SMC, whereas the DS was dried to 3% SMC. The results showed that DS caused early podding (3.3 days less), with reductions in plant height (11.4 cm), leaf area (1249.5 cm2), flowers (18.6), pods (27.4), seeds (37.0), grain yield (0.2 g), aboveground dry biomass (11.4 g) and harvest index (0.2 g), while increasing flower abortion (14.6) and seed biomass (1.5 g). However, diverse genotypic responses were observed to treatments, as well as water usage, FTSW and SMC that triggered pods which ranged from 1.12 to 1.89 L, 0.05 to 0.43 and 4.0% to 12.2%, respectively. A positive association between days taken and the amount of water used to terminate pods indicated that quicker‐triggering genotypes, such as Rupali and Genesis 836, consumed less water to develop pods than Flipper, ICCV_06109 and PBA Slasher did. Conversely, the negative association between the amount of water used and the number of pods triggered, seeds and grain yield explained the superior performance of Rupali and Genesis 836. These genotypes extracted less water (FTSW = 0.36 and 0.43; SMC = 10.3% and 12.2%, respectively) to develop pods and maintained favourable photosynthesis at lower transpiration rates for longer periods, allowing them to use residual moisture more efficiently. Our research offers crucial insights that can be beneficial to breeders and physiologists, paving the way for future studies aimed at developing drought‐tolerant genotypes. [ABSTRACT FROM AUTHOR]

In the eastern Indo‐Gangetic plains, chickpea is grown postrice cultivation mostly under rainfed condition with residual soil moisture which adversely affects branching as well as pod and seed development, ultimately resulting in substantial yield losses. The current study analysed the moisture stress response of 12 chickpea genotypes with control for different morpho‐physiological traits in two sets of field experiments carried out during the year 2017–18 and 2018–19. The current study observed varying response of chickpea genotypes under moisture stress condition with average yield reduction from 11.79% to 24.77%. Mean yield of genotypes under stress condition showed a strong positive association with yield index (1.00**) and stress tolerance index (0.915**). The biplot principal component analysis revealed maximum potential of three chickpea genotypes (DBGC 1, Pusa 256 and DBGC 2) for grain yield and biological yield under moisture stress condition. The correlation analysis showed a significant association of yield with physiological parameters such as photosynthetic rate (0.363**), stomatal conductance (0.364**) and transpiration rate (0.292*). The three higher yielding genotypes relatively maintained biological yield, yield plant−1, 100 seed weight and photosynthesis rate and showed reduced rates of stomatal conductance and transpiration under moisture stress condition. The study found variable genotypic response to moisture stress and showed that yield index as well as stress tolerance index was more effective to identify superior genotypes for moisture stress condition. The superior genotypes identified in the present study may be considered for rainfed areas of eastern Indo‐Gangetic plains and can be used in future chickpea breeding programs for drought tolerance.

This study aims to assess the microbial, nutritional, volatile, and sensory characteristics of rice, almond, and chickpea water kefir beverages during refrigerated storage. Plant-based kefirs contained significant amounts of lactic acid bacteria and yeasts. The microbial content of kefirs was stable during 14-day refrigerated storage. Lactic acid, acetic acid, and tartaric acid are commonly detected organic acids in kefir samples. Almond and chickpea kefirs were rich in potassium mineral. Almond kefir had the highest ethanol content among plant-based kefirs, followed by chickpea and rice-based kefirs. Ethyl acetate, acetic acid, propionic acid, hexanoic acid, and benzenemethanol were identified as key volatile compounds in almond kefir and chickpea kefir samples using a GC–MS detector during water kefir fermentation. According to sensory analysis results, significant differences are present for all test parameters except odor. Almond kefir was the most accepted, while the other two kefir samples were below the general acceptance level (P < 0.05). [ABSTRACT FROM AUTHOR]

In this study, our objective was to show the effects of pH and calcium on the techno functional properties of four pulse flours (chickpea, lentil, red lentil, and white bean) and the rheological properties of their pastes and gels. Five conditions were considered: a natural condition and four modifications (pH 3 and pH 5; with or without calcium addition). All measured properties varied with the type, condition, and the interaction among them. All flours exhibited high foaming capacity (44.3 − 78.8%) and emulsifying capacity (46.6 − 49.9%). The white bean flour showed a high water holding capacity (1.6 – 2.0 g/g), and the red lentil, lentil, and chickpea formed strong gels and high viscosity pastes. For the four pulses, the water holding capacity and foaming capacity of the flours and the viscosity of the pastes were improved by decreasing the pH (at 3 or 5) plus the addition of calcium. The hardness, elasticity, and resistance of gels obtained from pulse flours (except for white bean) were high when using natural conditions. Lowering pH resulted in a reduction of these parameters. Highlights: The properties of the flours were affected by pH and Ca differently depending on the pulse. The water holding capacity and foaming properties of pulse flours are improved by lowering pH and adding calcium. The viscosity of pulse flour pastes is improved by lowering the pH to 5 and 3. The strengths and elasticity of the pulse gels were reduced when the pH was decreased and calcium was added except for white beans. [ABSTRACT FROM AUTHOR]

Host diet is one of the key factors that shapes insect associated microbial communities, and the impact of dietary shift on abundance of microbial communities and insect fitness is poorly understood. Cigarette beetle (Lasioderma serricorne (F.)) are in close association with yeast symbionts for nutritional and defence benefits. The present study highlights that dietary source determines the yeast abundance in cigarette beetle and any change in diet induces a shift in yeast abundance. A general trendline of increase in yeast abundance during larval and pupal stage followed by a drop in adult stages of cigarette beetle was observed among all diet sources. The yeast abundance varied among diet sources and was significantly higher on natal (wheat) and reverted colonies compared to other exposed dietary sources. Yeast abundance in reverted colonies of soybean and bengal gram increased to the levels of those that were originally feeding on wheat suggesting a similar microbial structure among those diet sources. The correlation between yeast abundance and beetle biomass among diet guilds suggest a predictable relationship between yeast symbionts and diet source. The investigation can provide further insights on yeast symbiont abundance and food source specificity in cigarette beetle biology and management. [ABSTRACT FROM AUTHOR]

Background: Commercial/chemical pesticides are available to control Fusarium wilt of chickpea, but these antifungals have numerous environmental and human health hazards. Amongst various organic alternatives, use of antagonistic fungi like Trichoderma, is the most promising option. Although, Trichoderma spp. are known to control Fusarium wilt in chickpea but there are no reports that indicate the biocontrol efficacy of indigenous Trichoderma spp. against the local pathogen, in relation to environmental conditions. Methods: In the present study, biological control activity of Trichoderma species formulations viz., Trichoderma asperellum, Trichoderma harzianum (strain 1), and Trichoderma harzianum (strain 2), either singly or in the form of consortia, was investigated against Fusarium oxysporum f. sp. ciceris, the cause of Fusarium wilt in chickpea, in multiyear pot trials under open field conditions. The antagonistic effect of Trichoderma spp. was first evaluated in in vitro dual culture experiments. Then the effects of Trichoderma as well as F. oxysporum, were investigated on the morphological parameters, disease incidence (DI), and disease severity (DS) of chickpea plants grown in pots. Results: In dual culture experiments, all the Trichoderma species effectively reduced the mycelial growth of F. oxysporum. T. asperellum, T. harzianum (strain 1), and T. harzianum(strain 2) declined the mycelial growth of F. oxysporumby 37.6%, 40%, and 42%. In open field pot trials, the infestation of F. oxysporum in chickpea plants significantly reduced the morphological growth of chickpea. However, the application of T. asperellum, T. harzianum (strain 1), and T. harzianum (strain 2), either singly or in the form of consortia, significantly overcome the deleterious effects of the pathogen, thereby resulted in lower DI (22.2% and 11.1%) and DS (86% and 92%), and ultimately improved the shoot length, shoot fresh weight and shoot dry weight by 69% and 72%, 67% and 73%, 68% and 75%, during the years 1 and 2, respectively, in comparison with infested control. The present study concludes the usefulness and efficacy of Trichoderma species in controlling wilt disease of chickpea plants under variable weather conditions. [ABSTRACT FROM AUTHOR]

Three different fermented plant-based beverages were prepared and stored for a long period (50 days) to assess the effect of the quinoa-to-chickpea ratio on physicochemical stability and microbiological quality. Physicochemical stability was evaluated based on pH, acidity, Brix degrees, water-holding capacity (WHC), viscosity, and viscoelasticity. At the end of the long-term storage period, the pH, acidity, and WHC remained stable. During the entire storage period, the beverages maintained good bacterial, fungal, and lactic acid bacteria (LAB) counts. Quinoa and chickpea flour ratios of 50% showed a higher viscosity (18 Pa.s) and WHC (65%) during short-term storage (0–30 d), indicating that the presence of chickpea flour had a positive effect on these parameters, possibly because chickpea starch contains higher amounts of amylose and long-branch chain amylopectin, which impacts the retrogradation pattern under acidic and refrigerated conditions. However, at the end of storage (50 days), the same blend had a higher acidity, lower viscosity (0.78 Pa.s), and lower LAB counts (~1 × 108 CFU/mL), indicating that the increase in chickpea flour had an adverse long-term effect on these parameters. These results suggest that although different ratios of plant sources can improve the physical aspects, they need to be incorporated in a balanced manner to avoid negative effects on both short- and long-term storage, owing to the incorporation of different types of starches and proteins affecting the stability of the system.

High nutritional value and antioxidant properties make chickpea flour a valuable substitute for wheat flour, although its texture-forming abilities are different. The aim of this study was to investigate the possibility of increasing the content of bioactive compounds and antioxidant properties of shortbread cookies by simple partial or complete replacement of wheat flour with chickpea flour without considerable changes in texture, color, sensory properties, or acceptability. Shortbread cookies were made from wheat flour (0% of chickpea flour), wheat flour and chickpea flour (replacement of 25%, 50%, and 75%), and chickpea flour (100%). Generally, the increase in chickpea flour share resulted in an increase in protein, fat, and ash content, as well as antioxidant properties. Polyphenol content, flavonoid content, and antioxidant activities increased three- to sixfold in shortbread cookies containing chickpea flour in comparison to wheat cookies. The level of proteins increased about 50% and the antioxidant properties were three to six times higher than in wheat cookies. Cookies containing up to 75% chickpea flour were assessed as very good or good quality, while only cookies without wheat flour were assessed as sufficient quality. It could be concluded that part of the wheat flour content in shortbread cookies can be replaced by chickpea flour. Application of a 25% proportion of chickpea flour increases physicochemical properties without changes in sensory properties. Sensory quality was up to 75% lower, but antioxidant properties were increased. However, complete replacement of wheat flour in shortbread cookies without changing the recipe resulted in a product of slightly lower sensory quality. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the chemical composition of two chickpea varieties, 'Costa 2004' and 'El Patrón', and to characterize their proteins to determine their technological potential for the food industry. For this purpose, chickpea samples of both varieties from the 2019 harvest region of Guanajuato, Mexico, were obtained and chemically characterized to determine the protein fractions using electrophoretic and amino acid profiling. The chickpea variety 'Costa 2004' contained 3% less protein and 7% less dietary fiber content than the variety 'El Patrón'; whereas, the carbohydrate content of 'Costa 2004' was 4% greater. Additionally, the chickpeas demonstrated an antioxidant capacity ranging from 319 to 387 µMET/g and total phenol levels exceeding 500 mg/g. Among the protein fractions, globulins represented the highest proportion in both varieties of chickpea, at approximately 8.73 g/100 g ('Costa 2004') and 10.42 g/100 g ('El Patrón'), followed by albumin, at approximately 1.24 g/100 g and 1.47 g/100 g, respectively. The chickpea proteins ranged in molecular weight between 100 and 25 kDa, with particularly strong signals in the albumin and globulin bands. Regarding the amino acid profile, histidine was predominant in both varieties. In conclusion, both varieties of chickpea have high nutritional value and broad potential for technological use in the food industry. [ABSTRACT FROM AUTHOR]

Main conclusion: Our findings shed light on the regulation of anthocyanin and proanthocyanidin biosynthesis in chickpea seed coats. Expression of R2R3-MYB transcription factors CaLAP1 and CaLAP2 enhanced the anthocyanins and proanthocyanidins content in chickpea. The seed coat color is a major economic trait in leguminous crop chickpea (Cicer arietinum). Anthocyanins and proanthocyanidins (PAs) are two classes of flavonoids that mainly contribute to the flower, seed coat and color of Desi chickpea cultivars. Throughout the land plant lineage, the accumulation of anthocyanins and PAs is regulated by MYB and bHLH transcription factors (TFs), which form an MBW (MYB, bHLH, and WD40) complex. Here, we report two R2R3-MYB TFs in chickpea belonging to the anthocyanin-specific subgroup-6, CaLAP1 (Legume Anthocyanin Production 1), and CaLAP2 (Legume Anthocyanin Production 2), which are mainly expressed in the flowers and developmental stages of the seeds. CaLAP1 and CaLAP2 interact with TT8-like CabHLH1 and WD40, forming the MBW complex, and bind to the promoter sequences of anthocyanin- and PA biosynthetic genes CaCHS6, CaDFR2, CaANS, and CaANR, leading to anthocyanins and PA accumulation in the seed coat of chickpea. Moreover, these CaLAPs partially complement the anthocyanin-deficient phenotype in the Arabidopsis thaliana sextuple mutant seedlings. Overexpression of CaLAPs in chickpea resulted in significantly higher expression of anthocyanin and PA biosynthetic genes leading to a darker seed coat color with higher accumulation of anthocyanin and PA. Our findings show that CaLAPs positively modulate anthocyanin and PA content in seed coats, which might influence plant development and resistance to various biotic and abiotic stresses.

Aquafaba is the residual water from cooking chickpea in water. It has a high gelling ability, allowing it to create stable gels. However, those functional properties depend on the legume composition, genotype, cooking time, pressure, and temperature. This study aimed to evaluate the different processes for obtaining aquafaba and compare their nutritional composition and technological characteristics using a systematic review. The authors performed the systematic review by performing specific search strategies for Scopus, Web of Science, Pubmed, Lilacs, Google Scholar, and ProQuest. A total of 17 studies were analyzed. Of them, 17.64% (n = 3) used the wastewater from canned chickpeas, 17.64% (n = 3) compared the wastewater of canned chickpeas and dry grains, and 58.82% (n = 10) used dry chickpeas. Studies used different methods to analyze the protein content. The most used (n = 5) was the Association of Official Analytical Chemists (AOAC). The aquafaba presented carbohydrates at 2.03–2.59 g/100ml; protein at 0.0.8–2.8 g/100ml; and fat at 0.07–0.1 g/100ml. In general, preparing aquafaba followed: soaking (8–10 h at 4 °C—1 chickpea: 4 water), pressure cooking (30 min—2 chickpea: 3 water), and refrigerating (24h/4 °C). In general, the results showed the following steps to prepare aquafaba: soaking for 8–10 h at 4 °C at the proportion of 1:4 (chickpea:water), pressure cooking for 30 min in the proportion of 2:3 (chickpea: water), and refrigerating 24 h/4 °C. These procedures in a homemade aquafaba presented the best results, considering foam development and higher stability. The aquafaba from canned chickpeas has a higher foam-ability and lower emulsion properties than homemade cooking aquafaba. [ABSTRACT FROM AUTHOR]

The pigeon pea has high nutritional value and for diversifying utilization of sustainable legume crop i.e pigeon pea, for making alternative products with high nutritional value is an utmost to provide nutrient-rich food to the proving population. The present work focused on a comparative assessment of three pigeon pea varieties namely PAU 881, AL 882, and AL 201. The whole pigeon pea was assessed for test weight, coefficient of internal/external friction, angle of repose, and the pigeon pea flour was assessed for moisture, crude fat, crude protein, ash, crude fiber, carbohydrates, mineral content, fatty acid profile, foaming capacity, emulsification activity, pasting properties, and thermal properties. Further, batter was prepared using pigeon pea flour and water in the ratio of 1:1.6 (w/v) and analyzed rheological behavior of standard frying coating batter. The results revealed that the pigeon pea varieties had significant differences in proximate composition and functional properties. The pasting properties of AL 201 pigeon pea variety were significantly lower than the other pigeon pea varieties. In particular, the PAU 881 pigeon pea variety exhibited a better nutritional quality including macro and micro minerals. Moreover, the rheological parameters of PAU 881 were found better than the other two, indicating its potential for the preparation of frying coating batter like chickpea flour. Since chickpeas are widely used as a coating batter in a variety of products, underutilized pulses like pigeon pea are being investigated to see what potential they may have. This study will pave the future way of research and provide holistic view of approach to develop technology and engineering mechanization for various food products development.

The growth-regulating factor (GRF) and GRF-interacting factor (GIF) families encode plant-specific transcription factors and play vital roles in plant development and stress response processes. Although GRF and GIF genes have been identified in various plant species, there have been no reports of the analysis and identification of the GRF and GIF transcription factor families in chickpea (Cicer arietinum) and pigeonpea (Cajanus cajan). The present study identified seven CaGRFs, eleven CcGRFs, four CaGIFs, and four CcGIFs. The identified proteins were grouped into eight and three clades for GRFs and GIFs, respectively based on their phylogenetic relationships. A comprehensive in-silico analysis was performed to determine chromosomal location, sub-cellular localization, and types of regulatory elements present in the putative promoter region. Synteny analysis revealed that GRF and GIF genes showed diploid-polyploid topology in pigeonpea, but not in chickpea. Tissue-specific expression data at the vegetative and reproductive stages of the plant showed that GRFs and GIFs were strongly expressed in tissues like embryos, pods, and seeds, indicating that GRFs and GIFs play vital roles in plant growth and development. This research characterized GRF and GIF families and hints at their primary roles in the chickpea and pigeonpea growth and developmental process. Our findings provide potential gene resources and vital information on GRF and GIF gene families in chickpea and pigeonpea, which will help further understand the regulatory role of these gene families in plant growth and development.

Background: Cicer arietinum is a significant legume crop cultivated mainly in short-season environments, where early-flowering is a desirable trait to overcome terminal constraints. Despite its agricultural significance, the genetic control of flowering time in chickpea is not fully understood. In this study, we developed, phenotyped, re-sequenced and genetically characterized a pair of near-isogenic lines (NILs) with contrasting days to flowering to identify candidate gene variants potentially associated with flowering time. Results: In addition to days to flowering, noticeable differences in multiple shoot architecture traits were observed between the NILs. The resequencing data confirms that the NILs developed in this study serve as appropriate plant materials, effectively constraining genetic variation to specific regions and thereby establishing a valuable resource for future genetic and functional investigations in chickpea research. Leveraging bioinformatics tools and public genomic datasets, we identified homologs of flowering-related genes from Arabidopsis thaliana, including ELF3 and, for the first time in chickpea, MED16 and STO/BBX24, with variants among the NILs. Analysis of the allelic distribution of these genes revealed their preservation within chickpea diversity and their potential association with flowering time. Variants were also identified in members of the ERF and ARF gene families. Furthermore, in silico expression analysis was conducted elucidating their putative roles in flowering. Conclusions: While the gene CaELF3a is identified as a prominent candidate, this study also exposes new targets in chickpea, such as CaMED16b and LOC101499101 (BBX24-like), homologs of flowering-related genes in Arabidopsis, as well as ERF12 and ARF2. The in silico expression characterization and genetic variability analysis performed could contribute to their use as specific markers for chickpea breeding programs. This study lays the groundwork for future investigations utilizing this plant material, promising further insights into the complex mechanisms governing flowering time in chickpea.

Background: Water deficiency stress reduces yield in grain legumes, primarily due to a decrease in the pods number. Melatonin (ML) and 24-epibrassinolide (EBL) are recognized for their hormone-like properties that improve plant tolerance to abiotic stresses. This study aimed to assess the impact of different concentrations of ML (0, 100, and 200 µM) and EBL (0, 3, and 6 µM) on the growth, biochemical, and physiological characteristics of chickpea plants under water-stressed conditions. Results: The study's findings indicated that under water-stressed conditions, a decrease in seed (30%) and pod numbers (31%), 100-seed weight (17%), total chlorophyll content (46%), stomatal conductance (33%), as well as an increase in H2O2 (62%), malondialdehyde content (40%), and electrolyte leakage index (40%), resulted in a 40% reduction in chickpea plants grain yield. Our findings confirmed that under water-stressed conditions, seed oil, seed oil yield, and seed protein yield dropped by 20%, 55%, and 36%, respectively. The concurrent exogenous application of ML and EBL significantly reduces oxidative stress, plasma membrane damage, and reactive oxygen species (ROS) content. This treatment also leads to increased yield and its components, higher pigment content, enhanced oil and protein yield, and improved enzymatic and non-enzymatic antioxidant activities such as catalase, superoxide dismutase, polyphenol oxidase, ascorbate peroxidase, guaiacol peroxidase, flavonoid, and carotenoid. Furthermore, it promotes the accumulation of osmoprotectants such as proline, total soluble protein, and sugars. Conclusions: Our study found that ML and EBL act synergistically to regulate plant growth, photosynthesis, osmoprotectants accumulation, antioxidant defense systems, and maintain ROS homeostasis, thereby mitigating the adverse effects of water deficit conditions. ML and EBL are key regulatory network components in stressful conditions, with significant potential for future research and practical applications. The regulation metabolic pathways of ML and EBL in water-stressed remains unknown. As a result, future research should aim to elucidate the molecular mechanisms by employing genome editing, RNA sequencing, microarray, transcriptomic, proteomic, and metabolomic analyses to identify the mechanisms involved in plant responses to exogenous ML and EBL under water deficit conditions. Furthermore, the economical applications of synthetic ML and EBL could be an interesting strategy for improving plant tolerance. [ABSTRACT FROM AUTHOR]

BACKGROUND RESULTS CONCLUSION Future applications of high‐internal‐phase emulsions (HIPEs) are highly regarded, but poor freeze–thaw stability limits their utilization in frozen products. This study aimed to characterize the structure of chickpea protein microgel particles (HCPI) induced by NaCl and to assess its impact on the freeze–thaw stability of HIPEs.The results showed that NaCl induction (0–400 mmol L−1) increased the surface hydrophobicity (175.9–278.9) and interfacial adsorbed protein content (84.9%–91.3%) of HCPI. HIPEs prepared with HCPI induced by high concentration of NaCl exhibited superior flocculation index and centrifugal stability, and their freeze–thaw stability was better than that of natural chickpea protein. The increase in NaCl concentration reduced the droplet aggregation and coalescence index of the freeze–thaw emulsions, diminishing the precipitation of oil from the emulsion. Linear and nonlinear rheology showed that the strengthened gel structure (higher G′ values) restricted water flow and counteracted the damage to the interfacial film by ice crystals at 100–400 mmol L−1 NaCl, thus improving the viscoelasticity of the freeze–thaw emulsions. Finally, the thawing loss of surimi gel with HCPI‐200 HIPE was reduced by 2.04% compared to directly adding oil.This study provided a promising strategy to improve the freeze–thaw stability of HIPEs and reduce the thawing loss of frozen products. © 2024 Society of Chemical Industry.

The global food industry faces a critical challenge in ensuring sustainable practices to meet the demands of a growing population while minimizing environmental impact. At the same time, consumer awareness and the demand for quality products drive innovation and inspire positive changes in the food supply chain. Aiming to create a more sustainable and nutrient-rich alternative, this study is summarized by characterizing the physical and chemical characteristics of algae-enriched chickpea hummus: an innovative approach to popular food products. The algae-enriched hummuses were developed with an incorporation (6% w/w) of Gelidium corneum and Fucus vesiculosus seaweeds and Chlorella vulgaris (hetero and autotrophic) microalgae to reveal their technological potential and evaluate the nutritional and rheological characteristics relative to a control hummus (without algae). From a nutritional perspective, the main results indicated that hummus enriched with microalgae showed an increase in protein content and an improved mineral profile. This was particularly notable for the seaweed F. vesiculosus and the autotrophic microalga C. vulgaris, leading to claims of being a "source of" and "rich in" various minerals. Additionally, the antioxidant activity of hummus containing F. vesiculosus and C. vulgaris increased significantly compared to the control. From a rheological perspective, incorporating algae into the humus strengthened its structure. The microalgae further enhanced the dish's elasticity and firmness, thus improving this chickpea-based dish´s overall texture and quality. [ABSTRACT FROM AUTHOR]

Chickpea (Cicer arietinum L.) is an important legume crop worldwide. An emerging disease, basal stem rot with obvious wilt symptoms, was observed in the upper part of chickpea plants during the disease survey in Qiubei County of Yunnan Province. Three fungal isolates (ZD36-1, ZD36-2, and ZD36-3) were obtained from the diseased tissue of chickpea plants collected from the field. Those isolates were morphologically found to be similar to Diaporthe aspalathi. Molecular sequence analyses of multiple gene regions (ITS, tef1, tub2, cal, and his3) indicated that the three isolates showed a high identity with D. aspalathi. Pathogenicity and host range tests of the isolates were performed on the original host chickpea and eight other legume crops. The isolates were strongly pathogenic to chickpea and appeared highly pathogenic to soybean, cowpea, and mung bean; moderated or mild pathogenic to adzuki bean and common bean; however, the isolates did not cause symptoms on grass pea (Lathyrus sativus). Diaporthe aspalathi was previously reported as a main pathogen causing the southern stem canker in soybean. To our knowledge, this is the first report of D. aspalathi inducing basal stem rot on chickpea worldwide. [ABSTRACT FROM AUTHOR]

Seed germination and seedling development are the most susceptible stages to water deficit in the plant's life cycle. Silicon (Si) treatment was reported as a mitigator of water deficit stress effects for the growth and productivity of many crops. In this context, this study aims to explore the stimulatory effect of exogenous silicon (1.5 mM CaSiO3) application on germination and seedling growth of two chickpeas (Cicer arietinum L.) varieties, Zahor (ZA) and Farihane (FA), under two levels of water deficit, mild (-0.45 MPa) and severe stress (-0.75 MPa), induced using polyethylene glycol (PEG6000) for 8 days. Several germination traits, seedling growth attributes, and embryo reserve mobilization were assessed, as well as the molecules involved in osmoregulation and antioxidant defense systems. The results showed that both stress levels significantly (p < 0.001) reduced seed germination and seedling growth and induced oxidative stress in the studied chickpea varieties. Meanwhile, under severe stress, the Si treatment significantly (p < 0.001) improved the final germination percentage by 92.8% and 45.6%, the fresh weight by 13.5% and 54.16%, the shoot length by 47.8% and 82.14%, and the root length by 48.7% and 95.38% in ZA and FA varieties, respectively. Exogenous Si supply significantly (p < 0.05) counteracted the negative impact of the water deficit on seed germination by improving the reserve mobilization process. Si significantly (p < 0.05) mitigated water deficit-mediated oxidative stress by reducing electrolyte leakage, malondialdehyde, and hydrogen peroxide contents and by enhancing proline accumulation and enzymatic (superoxide dismutase and peroxidase) and non-enzymatic (total polyphenols and flavonoids) antioxidant activities. These findings suggested that Si might confer an improved tolerance of chickpea to the water deficit during germination and seedling growth. [ABSTRACT FROM AUTHOR]

Pulse crops, including beans, peas, chickpeas, and lentils, are vital sources of protein, fiber, and essential nutrients worldwide. They serve not only as staple foods but also as key components of sustainable agricultural practices, contributing to soil fertility through nitrogen fixation and enhancing overall productivity. However, pulse crops face numerous abiotic and biotic stresses mainly insect pest attack and pathogen invasion, which pose significant threats to pulse crops, impacting both production and food security. To overcome these challenges, plants have evolved diverse defense mechanisms, including the emission of specific volatile organic compounds (VOCs). These volatiles play crucial roles in plant communication, protection, and real-time health status indication. Monitoring VOCs offers a promising approach for early detection of pest infestations or pathogen infections, enabling the grower to take early action and decide on the proper control measure to minimize losses. The identification of plant-emitted VOCs requires robust and sensitive analytical techniques such as gas chromatography andmass spectrometry, which are themainly used techniques for in pulse crops studies. However, traditional methods have limitations, prompting the need for advanced, portable, and real-time detection alternatives, such as gas-sensing technologies. This paper provides a comprehensive review of VOC measuring methods, including extraction, separation, and analytical techniques, focusing on their application in pulse crops. Recent advancements in gas-sensing technologies are also discussed, highlighting their potential in enhancing crop protection and agricultural sustainability. [ABSTRACT FROM AUTHOR]

Phytophthora root rot (PRR), caused by Phytophthora medicaginis, is a major soil‐borne disease of chickpea in Australia. Breeding for PRR resistance is an effective approach to avoid significant yield loss. Genetic resistance has been identified in cultivated chickpea (Cicer arietinum) and in the wild relative C. echinospermum, with previous studies identifying independent genetic loci associated with each of these sources. However, the molecular mechanisms associated with PRR resistance are not known. RNA sequencing analysis employed in this study identified changes in gene expression in roots of three chickpea genotypes grown hydroponically, early post‐infection with P. medicaginis zoospores. Analyses of differentially expressed genes (DEG) identified the activation of a higher number of non‐specific R‐genes in a PRR‐susceptible variety than in the resistant genotypes, suggesting a whole plant resistance response occurring in chickpea against the pathogen. Contrasting molecular changes in signaling profiles, proteolysis and transcription factor pathways were observed in the cultivated and wild Cicer‐derived resistant genotypes. DEG patterns supported a hypothesis that increased root elongation and reduced adventitious root formation limit the pathogen entry points in the genotype containing the wild Cicer source of PRR resistance. Candidate resistance genes, including an aquaporin and a maltose transporter in the wild Cicer source and GDSL esterases/lipases in the cultivated source of resistance, were oppositely regulated. Increased knowledge of these genes and pathways will improve our understanding of molecular mechanisms controlling PRR resistance in chickpea, and support the development of elite chickpea varieties through molecular breeding approaches.

Salinity tolerance was studied in chickpea accessions from a germplasm collection and in cultivars from Kazakhstan. After NaCl treatment, significant differences were found between genotypes, which could be arranged into three groups. Those that performed poorest were found in group 1, comprising five ICC accessions with the lowest chlorophyll content, the highest leaf necrosis (LN), Na+ accumulation, malondialdehyde (MDA) content, and a low glutathione ratio GSH/GSSG. Two cultivars, Privo-1 and Tassay, representing group 2, were moderate in these traits, while the best performance was for group 3, containing two other cultivars, Krasnokutsky-123 and Looch, which were found to have mostly green plants and an exact opposite pattern of traits. Marker–trait association (MTA) between 6K DArT markers and four traits (LN, Na+, MDA, and GSH/GSSG) revealed the presence of four possible candidate genes in the chickpea genome that may be associated with the three groups. One gene, ATP-binding cassette, CaABCC6, was selected, and three haplotypes, A, D1, and D2, were identified in plants from the three groups. Two of the most salt-tolerant cultivars from group 3 were found to have haplotype D2 with a novel identified SNP. RT-qPCR analysis confirmed that this gene was strongly expressed after NaCl treatment in the parental- and breeding-line plants of haplotype D2. Mass spectrometry of seed proteins showed a higher accumulation of glutathione reductase and S-transferase, but not peroxidase, in the D2 haplotype. In conclusion, the CaABCC6 gene was hypothesized to be associated with a better response to oxidative stress via glutathione metabolism, while other candidate genes are likely involved in the control of chlorophyll content and Na+ accumulation.

Extrudates were first prepared through extrusion-cooking and air-drying of different formulations obtained through a D-optimal Mixture Design containing blends of rice flour (RF), green lentil flour (GL), chickpeas flour (CP), and tomato powder (TP) in different proportions. These extrudates were subjected to deep oil frying (DOF) at 200fiC or microwave roasting (MWR) at 75% power level (1000W oven) in order to develop desirable color and flavor characteristics. Physical properties including color (L*, a*, b*), expansion ratio (ER), breaking stress (BS) and antioxidant activity (AA) were evaluated, and the influence of product variables on output parameters was assessed. Increasing CP and GL in the formulations resulted in a decrease in the ER and an increase in the BS. However, the inclusion of CP and TP helped to produce snacks of golden yellow color and increased their overall acceptability. The addition of TP also improved the antioxidant activity of the resulting product. Both DOF and MWR resulted in a lower antioxidant activity; however, MWR led to more than 80% retention of the original antioxidants and higher sensory acceptability. ER and L* values had a strong positive correlation with the overall acceptability of products. The extrusion - air-drying - microwave roasting process produced healthy snacks with acceptable sensory quality, high protein (through added pulses), and enriched antioxidant (through added tomato powder) contents.

Intercropping is a traditional farming system that increases crop diversity to strengthen agroecosystem functions while decreasing chemical inputs and minimizing negative environmental effects of crop production. However, the effect of intercropping legume-cereal in enhancing nutrient uptake and use efficiency under low phosphorus (P) soils is poorly understood. Growth, nodulation, P uptake and use efficiency, and changes in inorganic P availability in the rhizosphere of intercropped species were thus investigated in a field experiment with durum wheat and chickpea either grown alone or intercropped. The results showed that both plant biomass and grain yield, and consequently, the amount of P uptake by intercropped durum wheat increased significantly (30%, 12%, and 46%, respectively) compared with sole cropping during the two seasons. P availability increased in the rhizosphere of the two species, either grown as sole crops or as intercrops, and was enhanced by intercropping. Moreover, total biomass, grain yield, and P uptake were significantly improved, as indicated by higher land equivalent ratio (LER > 1) in intercropping over sole cropping treatments. The increased biomass and grain yield for intercropped durum wheat were associated with the stimulation of P absorption and use efficiency. Furthermore, intercropped wheat was more competitive than their respective chickpea over two growing seasons. The results of this study suggest that changes in the intercropped chickpea rhizosphere may enhance plant growth, P uptake, and use efficiency of the intercropped wheat under low-P soils.

Background: Chickpea (Cicer arietinum L.) is the most important leguminous crop around the world. Fusarium wilt incited by Fusarium oxysporum f. sp. ciceris is a major biotic constraint in chickpea production. The present investigation was undertaken to evaluate the efficacy of plant extracts, fungicides and bio-agents against Fusarium oxysporum f. sp. ciceris under in vitro and field conditions. Methods: Plant extracts and fungicides were evaluated using poison food technique while antagonistic activity of bio-agents was studied using dual culture technique under in vitro conditions. Field trials were conducted to evaluate the efficacy of different plant extracts, fungicides and bio-agents against Fusarium wilt at Experimental Area of Plant Pathology, CCS HAU, Hisar. Result: Among thirteen plant extracts evaluated in vitro, neem leaves extract was found to be the most effective in inhibiting mycelial growth of F. oxysporum f. sp. ciceris followed by datura leaves’ and garlic cloves’ extract which were statistically at par. Out of six plant extracts tested against Fusarium wilt under field conditions, seed treatment with extracts of neem and datura leaves at 10% concentration were most effective and curtailed the wilt incidence by 39.02 and 34.14% along with 7.55 and 6.83% enhanced seed yield. Among fungicides, carbendazim 50 WP was the most toxic fungicide in restricting colony diameter of the pathogen with the least EC50 and EC90 values of 1.28 and 15.24 ppm a.i. followed by azoxystrobin 23 SC with corresponding values of 1.57 and 49.16 ppm a.i., respectively. Seed treatment with carbendazim 50 WP and azoxystrobin 23 SC were superior over other treatments and provided 88.41 and 85.98% reduction in disease incidence along with 12.85 and 10.99% higher seed yield over control. Among the bio-agents tested, T. viride and T. harzianum gave the best results in suppressing the pathogen growth in vitro and in minimizing the disease incidence coupled with improvement in seed yield under field conditions. The present study has provided chemical and non-chemical measures for integrated management of chickpea wilt [ABSTRACT FROM AUTHOR]

Background: The major constraint in rainfed chickpea cultivation is unavailability of short duration, wilt resistant and high yielding varieties in Chamarajanagara district. In this regard, an investigation was carried out to identify suitable high yielding varieties for Chamarajanagara District, Karnataka (Zone-6). Methods: As a part of on farm testing of ICAR-KVK, Chamarajanagara conducted a field experiment during rabi 2018-19, 2019-20 and 2020-21 (Three years) in farmers field at Kotamballi village. Four chickpea varieties viz., Annigere-1, JG-11, Jaki-9218 and BGD103 were tested under randomized complete block design (RCBD) which was replicated seven times. Result: The study revealed that chickpea variety BGD-103 recorded significantly higher grain yield (14.28 q/ha) and per cent protein content (20.10%) with the minimum disease incidence of 7.93 per cent. The growth and yield parameters were also better with BGD103 variety as compared to other varieties. The highest wilt incidence of 29.2 per cent was recorded with chickpea variety A-1 followed by JG-11 (26.09%). The highest net return of `.35703/ha and benefit cost ratio of 2.16 was recorded in BGD-103 compared to other varieties. The investigation revealed that BGD-103 was found to be suitable variety for rainfed black soils of Karnataka (Zone-6) due to minimum wilt incidence, short duration nature, higher seed yield and per day productivity.
