Chemodiversity, the diversity of specialised (secondary) metabolites, plays a crucial role in mediating interactions between plants and animals, including insect herbivores and mutualists. Chemodiversity can be observed at both the individual and the population level. However, the impacts of chemodiversity at these two levels on interactions between plants and floral visitors, mainly pollinators and floral herbivores (florivores), are only poorly understood. This study aimed to investigate the effects of chemodiversity at both individual (chemotype) and plot level on pollinators and florivores, examining their mutual interactions. To investigate these questions, we used individuals of the perennial Tanacetum vulgare differing in their terpenoid composition, representing different chemotypes. We planted individuals of five distinct chemotypes in a common garden design with homogeneous (five plants of the same chemotype) and heterogeneous (five different chemotypes) plots and observed flower visits in dependence of individual chemotype and plot type. Seeds were collected from a subset of plants and germination rates determined. Our findings revealed that chemodiversity at the plot level significantly influenced pollinator visitation, with more visits on plants of heterogeneous plots. We also observed marginally more pollinators on one of the chemotypes grown in homogeneous plots. In contrast, chemotype but not plot type had a significant effect on florivore visits. Pollinator and florivore species richness did not vary with plot type. Furthermore, a negative correlation was observed between pollinator and florivore visits in 1 year. Germination rates were positively correlated with pollinator visits and affected by chemotype but not by florivore visits or plot type. Synthesis. Our study emphasises the significance of the spatial level at which plant chemistry is perceived by flower visitors, potentially influencing the germination success of plants. Exploring the ecology of these visitors and the varying selection pressures they exert on floral chemistry can help to elucidate the evolutionary processes that maintain chemodiversity in natural environments.

Abstract\nNOVELTY STATEMENT\nHIGHLIGHTSThe effects of
Paenibacillus favisporus CHP14 inoculation on selenium (Se) accumulation and Se tolerance of Pakchoi were studied by a pot experiment conducted in greenhouse. The results revealed that the growth traits such as plant height, root length, and biomass were significantly elevated during CHP14 treatment at 0 ∼ 8.0 mg·kg−1 Se(IV) levels. CHP14-inoculated plants accumulated more Se in root and shoot, which were 24.1%∼57.3% and 7.5%∼50.9% higher than those of non-inoculated plants. The contents of leaf nitrogen (N), phosphorus (P), magnesium (Mg), and iron (Fe), as well as the ratio of indoleacetic acid and abscisic acid contents (IAA/ABA) were increased by CHP14 inoculation, and positively associated with photosynthetic pigment contents (p < 0.05). At ≥ 4.0 mg·kg−1 Se(IV) levels, superoxide dismutase, peroxidase, and glutathione peroxidase activities of Pakchoi roots were increased with CHP14 inoculation, by 9.9%∼17.1%, 28.4%∼40.7%, and 7.4%∼15.3%, respectively. Moreover, CHP14 inoculation enhanced ascorbate-glutathione (AsA-GSH) metabolism in roots by upregulating the related enzymes activities and antioxidant contents under excess Se(IV) stress. These findings suggest that CHP14 is beneficial to improve plant growth and enhance Se(IV) resistance of Pakchoi, and can be exploited as potential inoculants for phytoremediation process in Se contaminated soil.This work assesses the effects of plant growth-promoting bacterium (PGPB) on physiology and biochemistry of Pakchoi plant under different exogenous selenite levels.P. favisporus CHP14 inoculation was found to be a positive way for promoting plant growth, improving Se accumulation and reducing Se toxicity in plant. It also provides the first evidence that PGPB improves plant Se tolerance by influencing ascorbate-glutathione (AsA-GSH) cycle.Both Se deficiency and Se pollution cause a serious threat to the ecological environment and human health. The absorption of Se from soil by plant is not only a desirable way to supplement this micro-nutrient in human body, but also an effective method for Se remediation. However, the range between the beneficial and toxic doses of Se to plants is extremely narrow. The Se application slightly exceeding the required dose would significantly inhibit growth and Se accumulation in plants, since most of them have a very limited tolerance to Se. Plant growth-promoting bacteria (PGPBs) are drawing much attention due to their important benefits for improving resistance of plant to various biotic or abiotic stresses. Recent evidences have suggested that PGPBs may become the potential enhancers for Se biofortification. Therefore, the study on plant-bacteria interaction in Se-rich conditions should be strengthened. The significance of our research is in revealing the effect of endophyte inoculation on Se accumulation and Se tolerance of Pakchoi and in providing a microorganism material with potential application values for Se biofortification and improving Se tolerance of Pakchoi.

SUMMARY: Plants synthesize natural products via lineage‐specific offshoots of their core metabolic pathways, including fatty acid synthesis. Recent studies have shed light on new fatty acid‐derived natural products and their biosynthetic pathways in disparate plant species. Inspired by this progress, we set out to develop tools for exploring the evolution of fatty‐acid derived products. We sampled multiple species from all major clades of euphyllophytes, including ferns, gymnosperms, and angiosperms (monocots and eudicots), and we show that the compositional profiles (though not necessarily the total amounts) of fatty‐acid derived surface waxes from preserved plant specimens are consistent with those obtained from freshly collected tissue in a semi‐quantitative and sometimes quantitative manner. We then sampled herbarium specimens representing 57 monocot species to assess the phylogenetic distribution and evolution, of two fatty acid‐derived natural products found in that clade: beta‐diketones and alkylresorcinols. These chemical data, combined with analyses of 26 monocot genomes, revealed a co‐occurrence (though not necessarily a causal relationship) between whole genome duplication and the evolution of diketone synthases from an ancestral alkylresorcinol synthase‐like polyketide synthase. Limitations of using herbarium specimen wax profiles as proxies for those of fresh tissue seem likely to include effects from loss of epicuticular wax crystals, effects from preservation techniques, and variation in wax chemical profiles due to genotype or environment. Nevertheless, this work reinforces the widespread utility of herbarium specimens for studying leaf surface waxes (and possibly other chemical classes) and reveals some of the evolutionary history of fatty acid‐derived natural products within monocots. Significance Statement: Plant chemicals are key components in our food and medicine, and advances in genomic technologies are accelerating plant chemical research. However, access to tissue from specific plant species can still be rate limiting, especially for species that are difficult to cultivate, endangered, or inaccessible. Here, we demonstrate that herbarium specimens provide a semiquantitative proxy for the cuticular wax composition of their fresh counterparts, thus reducing the need to collect fresh tissue for studies of wax chemicals and suggesting the same may also be true of other plant chemical classes. We also demonstrate the utility of combining herbarium‐based plant chemical profiling with genomic analyses to understand the evolution of plant natural products. [ABSTRACT FROM AUTHOR]

Summary: Diversification of plant chemical phenotypes is typically associated with spatially and temporally variable plant–insect interactions. Floral scent is often assumed to be the target of pollinator‐mediated selection, whereas foliar compounds are considered targets of antagonist‐mediated selection. However, floral and vegetative phytochemicals can be biosynthetically linked and may thus evolve as integrated phenotypes.Utilizing a common garden of 28 populations of the perennial herb Arabis alpina (Brassicaceae), we investigated integration within and among floral scent compounds and foliar defense compounds (both volatile compounds and tissue‐bound glucosinolates).Within floral scent volatiles, foliar volatile compounds, and glucosinolates, phytochemicals were often positively correlated, and correlations were stronger within these groups than between them. Thus, we found no evidence of integration between compound groups indicating that these are free to evolve independently. Relative to self‐compatible populations, self‐incompatible populations experienced stronger correlations between floral scent compounds, and a trend toward lower integration between floral scent and foliar volatiles.Our study serves as a rare test of integration of multiple, physiologically related plant traits that each are potential targets of insect‐mediated selection. Our results suggest that independent evolutionary forces are likely to diversify different axes of plant chemistry without major constraints. [ABSTRACT FROM AUTHOR]

Cancer gradually continues to cause increasing numbers of deaths each year globally. In addition, the persistence and aggressiveness of multidrug-resistant (MDR) cancer cells make this disease a serious public health problem. However, scientists are making considerable efforts to understand the mechanisms of action of cell proliferation and to discover new cytotoxic agents capable of combating drug sensitive as well as MDR cancer cells; and the exploration of medicinal and phytochemical plants is a considerable avenue. This chapter reports on the contribution of the potential of Hypericum roeperianum and its constituents as a source of anticancer drugs. Scientific databases such as PubMed, ScienceDirect, Scopus, and Google Scholar were used to retrieve publications related to the cytotoxic and antiproliferative properties of H. roeperianum. The reported data were analyzed to highlight the cytotoxicity and the modes of action of botanicals and phytochemical from H. roeperianum. The results show that H. roeperianum and its constituents have beneficial cytotoxic properties and could be exploited in alternative medicine for the management of cancer including the recalcitrant phenotypes.

In the present review, the ethnomedicinal uses, the phytochemistry, and the pharmacological effects of established cytotoxic plants of the flora of Africa have been reported. The best botanical source of potential anticancer agents, as well as the best cytotoxic phytochemicals, were also identified and highlighted. The relationship between various health conditions in association with cancer was also given. It was shown that few evidenced cytotoxic are used to treat cancer as well as diseases with cancer-related symptoms, such as inflammatory diseases, parasitic infections, microbial and viral infections, cardiovascular diseases, central nervous system disorders, diabetes, and digestive system disorders. A total of 111 cytotoxic African medicinal plants belonging to 46 families are reported. Up to 50 potent African medicinal plants were identified as potentially suitable to fight at least one type of cancer. A total of 20 plants were identified to be suitable to fight the drug resistance of at least one type of cancer. One hundred and eight phytochemicals from African medicinal plants were identified as potentially suitable to fight at least one type of cancer. Phytochemicals identified as potent cytotoxic agents included 48 phenolics, 28 terpenoids, 26 alkaloids, 4 carbohydrates, and 2 fatty acids. A total of 42 phytoconstituents were identified to be suitable to fight the drug resistance of at least one type of cancer. This review constitutes a good collection for scientists, especially since it identifies new botanicals and phytochemicals that could undergo further in-depth studies to discover novel and powerful anti-cancer drugs. It also identifies the best classes of plant cytotoxic molecules, which could better guide scientists in the search for new anticancer agents. [ABSTRACT FROM AUTHOR]

Refractory cancers account for therapeutic failures and tremendous financial burdens due to malignancies. The discovery of new chemotherapeutic agents preventing the growth of both drug sensitive and multidrug-resistant (MDR) cancer cell lines is an imperative necessity. This has been a research approach of several research teams in various parts of the world. In this work, we have highlighted the cytotoxic effects of a potent African plant, Vepris soyauxii, and its constituents. The geographic distribution of the plant, as well as its ethnomedicinal uses, were also provided. Twenty-seven phytochemicals were isolated from various parts of the plant, including 16 alkaloids, 7 terpenoids, and 4 phenolics. The interesting cytotoxic potential of botanicals from V. soyauxii and its constituents was reported in several human cancer cell lines, including drug-sensitive and MDR phenotypes of leukemia, breast, colon, and brain cancers. Kihadanin B (18) and soyauxinium chloride (14) were identified as the most active principle of the plant. Scientists are strongly encouraged to intensify preclinical and clinical studies on the botanicals and phytochemicals from V. soyauxii to produce novel cytotoxic drugs to combat cancers including their refractory phenotypes.

Plants of the genus Erythrina have a significant history of medicinal use for the treatment of various ailments. Previous reports have shown the occurrence of various phytochemicals in Erythrina species with a wide range of biological activities. This book chapter reviews the information on the ethnomedicinal uses, phytochemistry, and antiproliferative potential of the genus Erythrina. The information on Erythrina species was compiled from electronic databases such as Google Scholar, Medline, PubMed, SciFinder, SCOPUS, Web of Science, Springer Link as well as books, and Ph.D. dissertations. Phytochemical studies of Erythrina species showed that alkaloids and flavonoids are their main secondary metabolites. Triterpenes, sterols, stilbenes, coumarins, and phenolic acids are also reported in the genus. Pharmacological investigations with crude extracts and isolated compounds from Erythrina species revealed a broad range of antiproliferative activity against several drug sensitive and multidrug-resistant (MDR) cancer cell lines. Among the isolated compounds, phenolic compounds mainly flavonoids (Abyssinoflavanones I, II, and VII, sigmoidin I, eryvarin B, erythraddison II-IV, warangalone, 5,4′-dihydroxy-2′-methoxy-8-(3,3-dimethylallyl)-2″,2″-dimethylpyrano [5,6:6,7]isoflavone, erymildbraedin A and B, echrenone b10, phaseollidin, erybraedin A, isoneorautenol, phaseollin, cristacarpin, and erystagallin A), terpenoids (oleanolic acid and maniladiol), and a phenolic derivative (excelsaperoxide) displayed potent antiproliferative activities. Globally, the reviewed data herein would be a valuable reference tool for future researchers seeking to explore the potential application of plants of the genus Erythrina for the development of anticancer agents.

Polygalae radix (PR) is the dried root of Polygala tenuifolia Willd. and Polygala sibirica L. and enjoys the reputation as the "key medicine for nourishing life." In this study, information about "Polygala tenuifolia Willd.," "Polygala sibirica L.," and "Yuanzhi" was retrieved from scientific databases, including Google Scholar, Baidu Scholar, Web of Science, PubMed, CNKI, and Wan Fang Data. Information from Chinese herbal medicine classics, Yaozhi Data, and the Gaide Chemical Network was also collected. Information related to botany, phytochemistry, pharmacology, toxicity, industrial applications, and processing is summarized in this paper to tap its potentialities and promote its further development and clinical application. More than 320 metabolites have been isolated from PR; saponins, xanthones, and oligosaccharide esters are the main functional metabolites. Pharmacological research shows that its pharmacological action mainly focuses on resisting nervous system diseases, and it also has the functions of anti-oxidation, anti-inflammation, anti-tumor, anti-pathogenic microorganisms and others. The gastrointestinal irritation of its saponins impeded its application, but this irritation can be reduced by controlling the dosage, compatibility with other herbs, or processing. The future progress of PR faces opportunities and challenges. More attention should be paid to the traditional application and processing methods of PR recorded in ancient books. The lack of safety and clinical studies has limited its application and transformation of achievements. Moreover, it is one-sided to take the content of only a few metabolites as the index of processing optimization and quality control, which cannot reflect the full pharmacological and toxicological activities of PR.

Huanglongbing (HLB), associated with the psyllid-vectored phloem-limited bacterium, Candidatus Liberibacter asiaticus (CLas), is a disease threat to all citrus production worldwide. Currently, there are no sustainable curative or prophylactic treatments available. In this study, we utilized mass spectrometry (MS)-based metabolomics in combination with 3D molecular mapping to visualize complex chemistries within plant tissues to explore how these chemistries change in vivo in HLB-infected trees. We demonstrate how spatial information from molecular maps of branches and single leaves yields insight into the biology not accessible otherwise. In particular, we found evidence that flavonoid biosynthesis is disrupted in HLB-infected trees, and an increase in the polyamine, feruloylputrescine, is highly correlated with an increase in disease severity. Based on mechanistic details revealed by these molecular maps, followed by metabolic modeling, we formulated and tested the hypothesis that CLas infection either directly or indirectly converts the precursor compound, ferulic acid, to feruloylputrescine to suppress the antimicrobial effects of ferulic acid and biosynthetically downstream flavonoids. Using in vitro bioassays, we demonstrated that ferulic acid and bioflavonoids are indeed highly bactericidal to CLas, with the activity on par with a reference antibiotic, oxytetracycline, recently approved for HLB management. We propose these compounds should be evaluated as therapeutics alternatives to the antibiotics for HLB treatment. Overall, the utilized 3D metabolic mapping approach provides a promising methodological framework to identify pathogen-specific inhibitory compounds in planta for potential prophylactic or therapeutic applications.

Studies are being conducted to develop strategies to reduce the adverse effects of salinity stress. In the present study, it was aimed to determine the interactive effects of salinity stress with biochar on plant growth-the physiological and biochemical attributes of forage peas (Pisum sativum ssp. arvense L.). Salt applications were carried out with irrigation water at concentrations of 0, 25, 50, 75, and 100 mM NaCl. The experiment was conducted using a randomized complete block design with three applications [control: 0 (B
0 ), 2.5% biochar (B1 ), and 5% biochar (B2 )], five salt doses [0 (S0 ), 25 (S1 ), 50 (S2 ), 75 (S3 ), and 100 (S4 ) mM NaCl], and three replications, arranged in a 3 × 5 factorial arrangement. In the salt-stressed environment, the highest plant height (18.75 cm) and stem diameter (1.71 mm) in forage pea seedlings were obtained with the application of B1 . The root fresh (0.59 g/plant) and dry weight (0.36 g/plant) were determined to be the highest in the B1 application, both in non-saline and saline environments. A decrease in plant chlorophyll content in forage pea plants was observed parallel to the increasing salt levels. Specifically, lower H2 O2 , MDA, and proline content were determined at all salt levels with biochar applications, while in the B0 application these values were recorded at the highest levels. Furthermore, in the study, it was observed that the CAT, POD, and SOD enzyme activities were at their lowest levels at all salt levels with the biochar application, while in the B0 application, these values were determined to be at the highest levels. There was a significant decrease in plant mineral content, excluding Cl and Na, parallel to the increasing salt levels. The findings of the study indicate that biochar amendment can enhance forage peas' growth by modulating the plant physiology and biochemistry under salt stress. Considering the plant growth parameters, no significant difference was detected between 2.5% and 5% biochar application. Therefore, application of 2.5 biochar may be recommended.

Objectives: Oxytropis DC is a perennial plant of Fabaceae family, which is widely distributed in the northern temperate zone. It is known as "locoweed" because of its toxic component swainsonine. However, it is widely used in Tibetan medicine and Mongolian medicine, mainly for the treatment of heat-clearing and detoxifying, pain-relieving, anti-inflammatory, hemostasis, and other diseases. To provide a basis for the further development and utilization of Oxytropis DC, the pieces of literature about the application, phytochemistry, pharmacological action, and toxicity of Oxytropis DC were reviewed and analyzed. Key findings: A total of 373 chemical constituents were found from Oxytropis DC, including flavonoids, alkaloids, steroids, terpenoids, and others. Pharmacological actions mainly include antitumor, antioxidation, anti-inflammatory, analgesic, antibacterial, antifibrosis, and other pharmacological actions, among them, the antitumor effect is particularly prominent. Summary: At present, studies on its pharmacological effects are mainly concentrated on the extracts, some flavonoids, and alkaloids. In the follow-up studies, research on the pharmacological activities of the other chemical constituents in Oxytropis should be strengthened. It has the potential to pave the way for research and development of novel Oxytropis medicines. [ABSTRACT FROM AUTHOR]

Argemone ochroleuca Sweet is an alien invasive weed dominating most cultivated lands, however, the phytochemicals present in this plant and the effects of these on the germination and growth of economically important crops such as maize are not well-documented. The objective of the study was to characterize the phytochemistry of the shoots and roots of A. ochroleuca and determine whether the extracts could inhibit the germination of maize seeds. The shoots and roots of A. ochroleuca were extracted in water, hexane, and acetone. Ten maize seeds were used in the germination bioassay. A phytochemical analysis was conducted using gas chromatography-mass spectrometry (GC-MS). The effects of the A. ochroleuca water, hexane, or acetone extracts on maize seed germination were concentration and plant-part dependent. The highest reduction was recorded from the water extract with 82%. Identified compounds with high percentages in A. ochroleuca were 9,12-octadecadienoic acid (Z,Z) and 9,12,15-octadecatrienoic acid, (Z,Z,Z)-. The present study indicated that A. ochroleuca extracts suppress the germination of maize seeds, likely due to the presence of both the identified and potentially unidentified phytochemicals that were not detected by the selected method. There is, however, a need to establish the relationship between the phytochemical compounds and the enzymes responsible for germination. [ABSTRACT FROM AUTHOR]

Taraxaci herba, as a traditional Chinese medicine, is the name of the Taraxacum genus in the Asteraceae family. Documented in the Tang Herbal Medicine (Tang Dynasty, AD 657–659), its medicinal properties cover a wide range of applications such as acute mastitis, lung abscess, conjunctival congestion, sore throat, damp-heat jaundice, and vision improvement. In the Chinese Pharmacopoeia (Edition 2020), more than 40 kinds of China-patented drugs containing Taraxaci herba were recorded. This review explores the evolving scientific understanding of Taraxaci herba, covering facets of ethnopharmacology, botany, phytochemistry, pharmacology, artificial cultivation, and quality control. In particular, the chemical constituents and pharmacological research are reviewed. Taraxaci herba has been certified as a traditional medicine plant, and its flavonoids, phenolic acids, and terpenoids have been identified and separated, which include Chicoric acid, taraxasterol, Taraxasteryl acetate, Chlorogenic acid, isorhamnetin, and luteolin; they are responsible for anti-inflammatory, antioxidant, antibacterial, anti-tumor, and anti-cancer activities. These findings validate the traditional uses of Taraxaci herba and lay the groundwork for further scientific exploration. The sources used in this study include Web of Science, Pubmed, the CNKI site, classic monographs, the Chinese Pharmacopoeia, the Chinese Medicine Dictionary, and doctoral and master's theses.

Associational effects, whereby plants influence the biotic interactions of their neighbors, are an important component of plant–insect interactions. Plant chemistry has been hypothesized to mediate these interactions. The role of chemistry in associational effects, however, has been unclear in part because the diversity of plant chemistry makes it difficult to tease apart the importance and roles of particular classes of compounds. We examined the chemical ecology of associational effects using backcross‐bred plants of the Solanum pennellii introgression lines. We used eight genotypes from the introgression line system to establish 14 unique neighborhood treatments that maximized differences in acyl sugars, proteinase inhibitor, and terpene chemical diversity. We found that the chemical traits of the neighboring plant, rather than simply the number of introgression lines within a neighborhood, influenced insect abundance on focal plants. Furthermore, within‐chemical class diversity had contrasting effects on herbivore and predator abundances, and depended on the frequency of neighboring plant chemotypes. Notably, we found insect mobility—flying versus crawling—played a key role in insect response to phytochemistry. We highlight that the frequency and chemical phenotype of plant neighbors underlie associational effects and suggest this may be an important mechanism in maintaining intraspecific phytochemical variation within plant populations.

Increasing the seed germination potential and seedling growth rates play a pivotal role in increasing overall crop productivity. Seed germination and early vegetative (seedling) growth are critical developmental stages in plants. High-power microwave (HPM) technology has facilitated both the emergence of novel applications and improvements to existing in agriculture. The implications of pulsed HPM on agriculture remain unexplored. In this study, we have investigated the effects of pulsed HPM exposure on barley germination and seedling growth, elucidating the plausible underlying mechanisms. Barley seeds underwent direct HPM irradiation, with 60 pulses by 2.04 mJ/pulse, across three distinct irradiation settings: dry, submerged in deionized (DI) water, and submerged in DI water one day before exposure. Seed germination significantly increased in all HPM-treated groups, where the HPM-dry group exhibited a notable increase, with a 2.48-fold rise at day 2 and a 1.9-fold increment at day 3. Similarly, all HPM-treated groups displayed significant enhancements in water uptake, and seedling growth (weight and length), as well as elevated levels of chlorophyll, carotenoids, and total soluble protein content. The obtained results indicate that when comparing three irradiation setting, HPM-dry showed the most promising effects. Condition HPM seed treatment increases the level of reactive species within the barley seedlings, thereby modulating plant biochemistry, physiology, and different cellular signaling cascades via induced enzymatic activities. Notably, the markers associated with plant growth are upregulated and growth inhibitory markers are downregulated post-HPM exposure. Under optimal HPM-dry treatment, auxin (IAA) levels increased threefold, while ABA levels decreased by up to 65 %. These molecular findings illuminate the intricate regulatory mechanisms governing phenotypic changes in barley seedlings subjected to HPM treatment. The results of this study might play a key role to understand molecular mechanisms after pulsed-HPM irradiation of seeds, contributing significantly to address the global need of sustainable crop yield. [Display omitted] • Pulsed high power microwaves (HPM) generated with main frequency 3.5 GHz. • Seed germination significantly increased in all HPM-treated groups. • HPM-treated groups displayed enhancements in water uptake and seedlings growth. • Growth markers upregulated and growth inhibitory markers downregulated by HPM. • Auxin (IAA) levels 3-fold increase, while ABA levels decreased up to 65 % by HPM.

The "Sci-Finder" was also utilized to find references and revise chemical structures. Referenced documents have been gathered from the 1960s to date. It also noted that Glochidion, phytochemistry, and pharmacology are likely the keywords to seek for references. Results: Over 240 naturally occurring phytochemicals were isolated and identified from various Glochidion tissues, including terpenoids, sterols, saponins, lignans, flavonoids, mono -phenols, megastigmanes, butenolides, glycosides, alkaloids, cyanogens, tocopherols, fatty acids, and others. Three naturally occurring triterpenoids glochidonol, glochidiol, and glochidone are the likely characteristic metabolites, being isolated frequently. Glochidion crude extracts and their isolated compounds have been demonstrated as potential agents in various pharmacological targets, such as cytotoxicity, antioxidant, antiinflammation, and neuron and liver protection. Conclusion: Several isolates acted as promising agents in pharmacological assays. The anticancer mechanisms of various triterpenoids and saponins, especially new and potential compounds, are expected. Pharmacological advancements to enhance the efficacies of Glochidion constituents, such as synergistic combinations and nano-drug formulations, are encouraged. [ABSTRACT FROM AUTHOR]

Maize is highly susceptible to drought, which affects growth and yield. This study investigated how bacterial volatile organic compounds (BVOCs) affect maize drought tolerance. Drought reduced shoot size but increased root length, an adaptation for accessing deeper soil moisture. BVOCs from strain D12 significantly increased root length and shoot growth under drought conditions. Drought also altered root biochemistry, decreasing enzyme activity, and increased osmolyte levels. BVOCs from strains F11 and FS4-14 further increased osmolyte levels but did not protect membranes from oxidative damage, while BVOCs from strains D12 and D7 strains reduced osmolyte levels and cell damage. In shoots, drought increased the levels of osmolytes and oxidative stress markers. BVOCs from FS4-14 had minimal effects on shoot biochemistry. BVOCs from D12 and F11 partially restored metabolic activity but did not reduce cell damage. BVOCs from D7 reduced metabolic activity and cell damage. These results suggest that BVOCs can modulate the biochemical response of maize to drought, with some strains evidencing the potential to enhance drought tolerance. [ABSTRACT FROM AUTHOR]

Rationale: Childhood precocious puberty (CPP) is a common pediatric endocrine disorder with significant associated risks. Zhibai Dihuang pill (ZBDHP), a classic recipe of the Qing dynasty with its efficacy of nourishing yin and clearing heat, can downregulate the expression of ESR1 in the uterus and ovaries, thereby inhibiting CPP. However, as of now, the main active ingredients and pharmacological mechanisms of ZBDHP remain unclear. Methods: A comprehensive approach was proposed using ultra‐high‐performance liquid chromatography coupled with quadrupole‐Exactive Orbitrap mass spectrometry (UHPLC‐Q‐Exactive Orbitrap‐MS) and network pharmacology to explore the potentially active constituents of ZBDHP and reveal the underlying mechanisms against CPP. Molecular docking was used to verify the possible mechanisms. Results: A total of 214 constituents derived were identified via UHPLC‐Q‐Exactive Orbitrap‐MS, and 12 of them were definitely characterized using reference standards. Subsequently, compounds tetrahydropalmatine, alisol C, 25‐anhydroalisol A 11‐acetate, hispidone, cavidine, alisol E, melianone, neogitogenin, denudatin B, and 16β‐hydroperoxyalisol B with related targets PIK3CA, HSD11B1, CYP19A1, AR, PTGS2, CDK2, NR3C1, MMP2, MMP1, and MAPK1 were regarded as key components and targets for ZBDHP treating CPP using the compound–target–pathway network. Besides, the results revealed that the pathways conduced obviously to therapeutic efficacy, including pathways in cancer, neuroactive ligand–receptor interaction, and cyclic adenosine monophosphate(cAMP) signaling pathways. Molecular docking indicated that PIK3CA, HSD11B1, and CYP19A1 exhibited high affinities to corresponding compounds. Overall, the study determined the multicomponent, multitarget, and multipathway mechanisms of ZBDHP against CPP. Conclusions: This study provided a new method for exploring the chemical constituents and pharmacology mechanism of traditional Chinese medicine. [ABSTRACT FROM AUTHOR]

Introduction: Bone tissue engineering seeks innovative materials that support cell growth and regeneration. Electrospun nanofibers, with their high surface area and tunable properties, serve as promising scaffolds. This study explores the incorporation of flaxseed extract, rich in polyphenolic compounds, into polyvinyl alcohol (PVA) nanofibers to improve their application in bone tissue engineering. Methods: High-performance liquid chromatography (HPLC) identified ten key compounds in flaxseed extract, including polyphenolic acids and flavonoids. PVA nanofiberswere fabricated with 30 wt.% flaxseed extract (P70/E30) via electrospinning. We optimized characteristics like diameter, hydrophilicity, swelling behavior, and hydrolytic degradation. MG-63 osteoblast cultures were used to assess scaffold efficacy through cell adhesion, proliferation, viability (MTT assay), and differentiation. RT-qPCR measured expression of osteogenic genes RUNX2, COL1A1, and OCN. Results: Flaxseed extract increased nanofiber diameter from 252 nm (pure PVA) to 435 nm (P70/E30). P70/E30 nanofibers showed higher cell viability (102.6% vs. 74.5% for pure PVA), although adhesion decreased (151 vs. 206 cells/section). Notably, P70/E30 enhanced osteoblast differentiation, significantly upregulating RUNX2, COL1A1, and OCN genes. Discussion: Flaxseed extract incorporation into PVA nanofibers enhances bone tissue engineering by boosting osteoblast proliferation and differentiation, despite reduced adhesion. These properties suggest P70/E30's potential for regenerative medicine, emphasizing scaffold optimization for biomedical applications. [ABSTRACT FROM AUTHOR]

High salinity reduces agriculture production and quality, negatively affecting the global economy. Zinc oxide nanoparticles (ZnO-NPs) enhance plant metabolism and abiotic stress tolerance. This study investigated the effects of 2 g/L foliar Zinc oxide NPs on Zea mays L. plants to ameliorate 150 mM NaCl-induced salt stress. After precipitation, ZnO-NPs were examined by UV–visible spectroscopy, transmission electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray, and particle size distribution. This study examined plant height, stem diameter (width), area of leaves, chlorophyll levels, hydrolyzable sugars, free amino acids, protein, proline, hydrogen peroxide, and malondialdehyde. Gas chromatographic analysis quantified long-chain fatty acids, and following harvest, leaves, stalks, cobs, seeds, and seeds per row were weighed. The leaves' acid and neutral detergent fibers were measured along with the seeds' starch, fat, and protein. Plant growth and chlorophyll concentration decreased under salt stress. All treatments showed significant changes in maize plant growth and development after applying zinc oxide NPs. ZnO-NPs increased chlorophyll and lowered stress. ZnO-NPs enhanced the ability of maize plants to withstand the adverse conditions of saline soils or low-quality irrigation water. This field study investigated the effect of zinc oxide nanoparticles on maize plant leaves when saline water is utilized for growth season water. This study also examined how this foliar treatment affected plant biochemistry, morphology, fatty acid synthesis, and crop production when NaCl is present and when it is not. [ABSTRACT FROM AUTHOR]

Plant diseases are caused by various microorganisms such as bacteria, fungi, viruses, and nematodes. These diseases impact crop growth, reduce produce quality, and lead to financial losses. Plant disease can be caused by single pathogens or by interactions called "disease complexes", involving two or more pathogens. In these cases, the disease severity caused by the pathogens combined is greater than the sum of the disease caused by each pathogen alone. disease complexes formed among plant-parasitic nematodes (PPNs) with bacteria, fungi, or viruses, can occur. PPNs either enhance the other pathogen incidence and severity or are necessary for disease symptoms to be expressed. PPNs can do so by being wounding agents, vectors, modifiers of plant biochemistry and physiology, or altering the rhizosphere microbiome. This review identifies several PPNs-plant pathogens disease complexes in crop production to discuss how understanding such interactions is key for improving management practices.

Cancer refers to the proliferation and multiplication of aberrant cells inside the human body, characterized by their capacity to proliferate and infiltrate various anatomical regions. Numerous biochemical pathways and signaling molecules have an impact on the cancer auto biogenesis process. The regulation of crucial cellular processes necessary for cell survival and proliferation, which are triggered by phytochemicals, is significantly influenced by signaling pathways. These pathways or components are regulated by phytochemicals. Medicinal plants are a significant reservoir of diverse anticancer medications employed in chemotherapy. The anticancer effects of phytochemicals are mediated by several methods, including induction of apoptosis, cessation of the cell cycle, inhibition of kinases, and prevention of carcinogenic substances. This paper analyzes the phytochemistry of seven prominent plant constituents, namely, alkaloids, tannins, flavonoids, phenols, steroids, terpenoids, and saponins, focusing on the involvement of the MAPK/ERK pathway, TNF signaling, death receptors, p53, p38, and actin dynamics. Hence, this review has examined a range of phytochemicals, encompassing their structural characteristics and potential anticancer mechanisms. It has underscored the significance of plant-derived bioactive compounds in the prevention of cancer, utilizing diverse molecular pathways. In addition, this endeavor also seeks to incentivize scientists to carry out clinical trials on anticancer medications derived from plants. [ABSTRACT FROM AUTHOR]

Global biogeochemical cycles have been widely altered due to human activities, potentially compromising the ability of plants to regulate their metabolism. We grew experimental herbaceous communities simulating the understory of eucalypt forests from southeastern Australia to evaluate the effects of elevated CO2 (400 vs. 650 ppm) and changes in soil resource availability (high-low water and high-low P) on the concentration of fourteen essential plant macro- and micronutrients, and their degree of coupling. Coupling was based on correlations among all elements in absolute value and a null modeling approach. According to the ancient nature of Australian soils, P addition was the main driver of changes in plant tissue chemistry, increasing the concentrations of P, Mg, Ca, and Mn and reducing the concentrations of C, N, S, Na, and Cu. Most treatment combinations showed coupled patterns of plant elements, particularly under ambient CO2. However, under elevated CO2, elements in plant tissues became more decoupled, which was interpreted as the result of a lack of enough supply of a range of elements to satisfy greater demands. Across treatments, P, Mn, and N were the least coupled elements, while K, Ca, and Fe were the most coupled ones. We provide evidence that plant element coupling was positively related to the concentration and coupling of elements measured in soils worldwide, suggesting that plant element coupling is conserved. Our results provide compelling evidence that evaluating the coupling of a representative range of chemical elements in plant tissues may represent a highly novel and powerful indicator of nutritional mismatches between demand and supply under specific environmental circumstances, including in a resource-altered global change context.

• Nutritional aspects of the C. lanatus seeds were found as high for antioxidant activity. • Antimicrobial activity has higher affinity by the presence of various phytochemicals. • DPPH and FRAP antioxidant assays supported the radical scavenging activity. • The arrest of cell cycle of A549 cells in the G2 phase and cell viability were possessed to be greater in. • The ethanolic seed extract of C. lanatus has shown good anticancer potential against A549 cells. Cancer is a leading dangerous death-causing disease in millions over the world. It arises due to the uncontrolled growth of mal-functioned cells and formed as tumors. The disease can affect any part of the body. Still, it is a quest to find anti-cancer drugs which has been the major research endeavor around the globe. Traditionally humans use plants and their derived products as a source to cure various diseases. In recent years many researches had paved the way to use plant-based drugs. The current research aims to evaluate the anticancer activity of Citrullus lanatus seeds against A549 lung carcinoma epithelial cell lines. The study uses C. lanatus seeds which naturally contains antioxidants and phytochemicals that prevent cancer cell proliferation. The ethanolic seed extract of C. lanatus showed the presence of phytochemicals such as saponins, alkaloids, proteins and flavonoids by preliminary screening. The extract was tested for its anti-inflammatory showing 96.16 % at maximum concentration. The microbial assays also showed good signs of inhibition against the microorganisms by forming a zone of inhibition. The safety and efficacy of the extract were determined by MTT assay for the cytotoxicity using A549 cancer cell lines and non-cancerous cell lines. The IC50 concentration of C. lanatus seed extract showed dosage dependently at 51.73 μg/ml for A549 cell lines. They also resulted in significant induced cell cycle arrest and apoptosis at the G2 phase by inhibiting the A549 cell line proliferation.

In recent decades, the interest of the scientific community in plant space biology increased based on the certainty that cultivating higher plants in space is imperative for prolonged human missions. The cultivation of plants in space assumes great relevance moved by the consideration that there is a pivotal need to improve resource regeneration and onboard production of plant-based food, thus reducing the supply of resources from Earth. Therefore, the hereby paper provides an overview on the evolution of the interest in plant space biology from 2000 to 2023, basing the search on specific keyword combinations. The study encompasses (i) a proper quantitative search on the Scopus database; (ii) keyword frequencies and clustering analysis, (iii) a keyword network and time-gradient analysis and (iv) an elaboration of knowledge gaps comparing our results and recent reviews. Results highlighted an increase in publications in the last 10 years and a specific time-gradient related shifting on subtopics such as in situ resource utilization (ISRU) application and food production in a space mission context. Currently, knowledge gaps were identified in four research areas related to water dynamics in extra-terrestrial environments, plant physiology and biochemistry in response to growth on regolith, interactions with fertilizers, and plant/soil microbiome. Identifying these gaps will allow to canalize future efforts of space research where needed, facing the unsolved questions. Our analysis pointed out that space plant biology turned out to be oriented towards short and long-term space mission applications for improving resource regeneration and onboard/extraterrestrial-grounded production of plant-based food, thereby diminishing reliance on Earth for resupply. • The scientific community's interest in plant space biology increased in the perspective of prolonged human missions. • The bibliometric analysis highlighted a general increase in publications in the last ten years. • Publications shifted their focus on subtopics such as ISRU application and food production in a space mission context. • Main identified knowledge gaps are water dynamics in space, plant growth on mars-like soils, and plant/soil microbiome.

Assessment of the dynamics of rosemary (Rosmarinus officinalis L) is essential in the production of essential oils (EOs) in Morocco, considering the country is one of the main producers of rosemary EO. In this study, the authors aimed to examine the influence of harvesting period and environmental factors on the dynamics of rosemary EO, mainly its composition. Samples were collected from four sites in northeastern Morocco on a monthly basis between July 2021 and June 2022. Subsequently, quantitative and qualitative analyses by hydrodistillation and gas chromatography were performed to determine the yield and composition of EOs. On average, EO yields ranged from 2.3 to 3% across the four sites; they were highest in summer and lowest in autumn. A moderate negative correlation (r = -0.59, p < 0.05) was observed between precipitation and EO yield, while temperature had a moderately positive influence. A total of 17 chemical compounds, representing 88.9-99.1% of the EO extracts, were identified and consisted mainly of 1,8-cineole (44.2-46.6%), camphor (14.8-16.8%), borneol (7.5-9.1%), and a-pinene (5.2-5.9%). Harvesting period strongly influenced EO composition, with the highest concentrations of 1,8-cineole and a-pinene were recorded during the summer period (July and August), while the concentrations of borneol, camphor, and terpineol were highest in winter (December and January) and late spring. The findings of the study highlight the importance of monitoring the factors that influence the chemical composition of rosemary EO, thus providing a knowledge base that would help improve the quality and economic value of rosemary EO production in the region.

Silybum marianum (L.) Gaertn, a herbaceous plant with a long history in traditional medicine for the treatment of hepatobiliary diseases, particularly in Europe, which has attracted attention for its remarkable therapeutic effect. This review systematically summarizes the research progress in the botany, phytochemistry, pharmacology, comprehensive utilization and synthetic biology of S. marianum. Up to now, more than 20 types of flavonolignan components have been isolated from S. marianum. In addition, the rearch on fatty acids and triterpenoids is also constantly improving. Among them, silybin is the most active compound in flavonolignans components. Its pharmacological effects in vivo and in vitro include anti-inflammatory, antioxidant, anti-tumour, hypoglycaemic, neuroprotective and immunoregulatory properties. The use of coniferyl alcohol and taxifolin as substrates to produce silybin and isosilybin under the action of enzyme catalysis is the commonly used biosynthetic pathway of silymarin, which provides support for a comprehensive analysis of the synthetic pathway of silymarin. In addition to medicinal use, the extracts of plants also have broad application prospects in the production of food, healthcare products, cosmetics and other aspects. In addition, the chemical composition, pharmacological mechanism and synthetic biology of S. marianum need to be further studied, which is very important for its clinical efficacy and resource development.
