Goji berry (Lycium barbarum L.) is a nutrient‐rich fruit and has received enormous interest for its health benefits. The beneficial effects of goji berry are linked to the absorption of bioactive compounds within the gastrointestinal digestion process and colon fermentation. Nonetheless, how certain bioactive compounds were released, and metabolism changed of the consumption of whole goji berries were still unclear. Therefore, the present study aimed to evaluate the digestion characteristics of key bioactive compounds in whole goji berries with an in vitro digestion model, and the effects of whole goji berries on the structure of gut microbiota were also investigated. Results showed that a significant release of carbohydrates during the digestion process, peaking within the first 15 min of the intestinal phase (421.4 ± 5.82 mg GE/g, dry weight, respectively), was observed, and the phenolic release reached the highest in the first 15 min of the gastric phase. Meanwhile, the bioaccessibilities of phenolic compounds and carbohydrates were determined to be 63.87% and 80.40%, respectively, after intestinal digestion. In addition, the undigested fractions of goji berries could be further fermented to produce short‐chain fatty acids, which decreased the colon pH value (from 7.38 to 6.71) as well as the Firmicutes/Bacteroidetes ratio. Moreover, the goji berries regulated the composition of gut microbiota by promoting beneficial bacteria such as Bacteroides, Parabacteroides, and Paraclostridium, whereas inhibiting the proliferation of harmful bacteria (e.g., Fusobacterium). Our results indicated that the goji berry exhibited significant bioactivity during the digestion and fermentation stage and might provide some new insights into the utilization of goji berries in healthy food processing.

Objective: To isolate and purify the polysaccharides from Lycium barbarum and study its in vitro antioxidant activity and in vivo anti-aging effect. Methods: Crude polysaccharides from Lycium barbarum were obtained by water extraction and alcohol precipitation, and then LBP was isolated and purified from crude polysaccharides by Sevage reagent and DEAE-52 cellulose ion exchange resin. By measuring the scavenging ability of LBP to DPPH free radical, hydroxyl radical and ABTS+ free radical, and Fe3+ reduction, the antioxidant ability of LBP in vitro was evaluated. The aging mouse model was established by D-galactose. After administration, the body weights and organ indexes of mice in each group were compared. The levels of MDA, SOD, GSH-Px and CAT in serum, liver and brain were measured. The protein expression of Nrf-2 and HO-1 in liver tissue was detected by Western blotting. Results: The content of LBP after isolation and purification was 86.64%±2.34%. The IC50 values of scavenging ability of LBP to DPPH free radical, hydroxyl radical and ABTS+ free radical were 0.2081±0.0182, 0.7132±0.0220 and 0.3646±0.0138 mg/mL, respectively. Compared with the model group, the body weights and organ indexes of the mice in positive and high dose of LBP groups were significantly increased (P<0.05 or P<0.01). The levels of SOD, CAT and GSH-Px in serum, liver and brain of mice in positive and high dose of LBP groups were significantly increased, and the level of MDA was significantly decreased (P<0.01). The expression level of Nrf-2 protein in liver tissue increased significantly except for in the low dose of LBP group (P<0.05), and the expression level of HO-1 protein increased significantly in all groups (P<0.05 or P<0.01). Conclusion: LBP from Lycium barbarum has strong antioxidant ability and certain anti-aging effect, and its mechanism may be related to Nrf-2/HO-1 signal pathway. [ABSTRACT FROM AUTHOR]

To investigate the effects of different typical exogenous salt concentrations on total soil salinity and the growth of Lycium barbarum under brackish water irrigation, and to determine the salinity threshold of irrigated brackish water that is conducive to the normal growth of Lycium barbarum while mitigating soil salinity accumulation. Four typical exogenous salts (NaCl, CaCl2, NaHCO3, Na2SO4) were selected and set at four concentrations (0.1, 0.5, 2.0, 4.0 g L−1) to conduct a field crossover experiments in the downstream region of the Hetao Irrigation District. The results showed that in the same fertility period, the growth rates of new branches, ground diameter, and crown width first increased and then decreased with rising concentrations of NaCl, CaCl2, and Na2SO4, but showed an inverse relationship with NaHCO3 concentrations. Furthermore, increasing salt concentrations linearly reduced the yield of dry fruits from Lycium barbarum and led to a notable accumulation of total soil salts. Utilizing an experimental research approach, a comprehensive analysis of involving multiple growth indices, stable yield, and soil salinity control of Lycium barbarum revealed that optimal growth occurs at salt concentrations of 0.1–0.5 g L−1 for different water quality areas within the irrigation area; using the method of path analysis identified the total soil salt and crown width as the primary direct and indirect factors influencing the yield of Lycium barbarum. The results of this study provide scientific basis and significant theoretical support for the safe and rational utilization of brackish water and cultivation of Lycium barbarum in typical regions with varying saline water qualities of Hetao irrigation area.

【Objective】 This paper is to compare the composition of rhizoplane fungal communities in susceptible strain ‘Ningqi-5’ between the healthy and diseased plants in the two planting areas (QXBZ and QTBZ), as well as the isolated rot root fungi. It is also to clarify the pathogens causing root rot disease in ‘Ningqi-5’, and to explore the reasons for the root rot disease in ‘Ningqi-5’.【Method】High-throughput technology was applied to investigate the compositional characteristics of the rhizoplane fungal community. Tissue isolation method was to isolate the rot-root fungi the decayed roots of Lycium barbarum. They were taxonomically identified based on the morphological characteristics and the sequences of ITS and EF-1α gene fragments. The pathogenicity bythe rotten-root fungi was verified based on Koch's law.【Result】 The root rhizoplane fungal community composition differed significantly between the healthy and diseased plants of ‘Ningqi-5’ in both planting areas, showing the increase in relative abundance of Fusarium and decrease in relative abundance of Mortierella in the diseased plants, accompanying with the increase of unknown taxa like Fusicolla and Pseudogymnoascus. While the fungal community structure on the rhizoplane of the healthy plants in both planting areas tended to be consistent. The 36 strains isolated from the rotten rot of QXBZ were classified as Fusarium oxysporum, F. solani, Earliella scabrosa, Rhizoctonia solani, and Penicillium pimiteouiense. The 29 strains isolated from the rotten rot of QTBZ were classified as F. oxysporum, F. solani, E. scabrosa, Clonostachys rosea, P. pimiteouiense, F. andiyazi and Acremonium persicinum. Isolation frequency of F. solani was the highest in both planting areas, followed by F. oxysporum. Based on the artificial infection test, F. solani, F. oxysporum, R. solani, and F. andiyazi were identified as the pathogens of ‘Ningqi-5’ root rot disease, among which F. andiyazi was a newly discovered pathogen of L. barbarum root rot.【Conclusion】In this study, it is clarified that the occurrence of ‘Ningqi-5’ root rot disease is mainly closely related to the changes in the structure of the root rhizoplane fungal community and pathogens. F. solani, F. oxysporum, F. andiyazi, and R. Solani are the pathogens of ‘Ningqi-5’ root rot disease. [ABSTRACT FROM AUTHOR]

Traditional Chinese medical literature contains numerous records of many traditional Chinese herbal medicines that exhibit efficacy in enhancing resistance to cold, yet there is a lack of scientific explanation. Lycium barbarum is among the herbal medicines that are explicitly documented to enhance resistance to cold in the "Ben Cao Gang Mu (Compendium of Materia Medica)". Herein, we investigated L. barbarum polysaccharide (LBP)‐induced browning of inguinal white adipose tissue (iWAT), energy expenditure and thermogenic function in a long‐term (4 months) treatment mouse model. LBP supplementation resulted in a significant reduction in weight and adipocyte size in iWAT, along with increased gut microbiota diversity. Specifically, the levels of Lachnospiraceae, Ruminococcaceae and Bacteroidaceae (short‐chain fatty acid‐producing bacteria) were elevated, leading to a higher level of short‐chain fatty acids (SCFAs) in the caecal content. These effects subsequently triggered the release of glucagon‐like peptide‐1 (GLP‐1) and activated the CREB/PGC1α signaling pathway in iWAT, thereby increasing energy expenditure and enhancing thermogenic function. The antibiotic treatment experiments confirmed that the LBP‐mediated gut microbiota participated in the process of iWAT browning. In summary, our findings provide the first scientific explanation and mechanistic insights into the cold resistance of L. barbarum and identify potentially safe natural product supplements for individuals in alpine areas.

In order to obtain endophytic selenium-rich yeast from Lycium barbarum with strong ability producing alcohol and aroma, and then promote the selenium-rich fermentation products and improve the flavor, this study took the endophytic yeast of L. barbarum stored in the laboratory as experimental materials, and the yeast with strong selenium-rich ability was obtained through the initial screening of selenium-resistant method and red selenium methods. Atmospheric room temperature plasma (ARTP) technology was used to obtain mutant strains and through TTC medium, Duchenne tubule fermentation, alcohol production, ester and acid production, tolerance and other experiments to screen out the target strains of aroma enhancement and high alcohol production. The content of selenium in yeast cell and fermentation liquid was determined by hydride generation atomic fluorescence spectrometry. The results showed that M1 Saccharomyces cerevisiae and M16 Clavispora lusitaniae were obtained by primary selenium screening, the mutagenic strain M1-5 of S. cerevisiae with higher alcohol production capacity and the mutagenic strain M16-28 of C. lusitaniae with higher aroma production capacity were obtained through ARTP mutagenesis. The alcohol production capacity of M1-5 increased by 38.07% compared with M1, and the ester production capacity of M16-28 increased by 107.62% compared with M16, and the genetic stability was good. The selenium contents in the intracellular and fermentation broth of the M1-5 strains were 204.8 and 1158 μg/L, respectively, and in M16-28 were 666.45μg/L and 1830 μg/L, respectively. Therefore, the selenium enrichment capacity of M16-28 was higher than that of M1-5, and the selenium content of fermentation liquid was extremely significantly higher than that of yeast cells (P

To further explore the metabolism of Lycium barbarum polysaccharides, the cell wall microstructure of Lycium barbarum fruits in different growth periods was observed by transmission electron microscopy, and the cell wall polysaccharide content and its degrading enzyme activity were extracted by chemical method. The changes of polysaccharide components in cell wall of Lycium barbarum fruits in different growth periods were analyzed by microcopolymer Raman spectroscopy. The correlation between the content of polysaccharide in cell wall and the activity of degrading enzyme was analyzed. The results showed that the changes of cell wall structure mainly occurred during 28~35 d, with the cell wall becoming significantly thinner, pectin degrading, and the cell wall structure gradually collapsing. Cell wall material (CWM) content increased first and then decreased, and water-soluble pectin (WSP) content increased significantly (P

Lycium barbarum, a plant belonging to the Solanaceae family, is widely used in China due to its abundant nutritional value. Although the current mechanized harvesting method of L. barbarum has effectively minimized production expenses, it continues to have the challenge of inconsistent quality of the produced L. barbarum. The objective of this paper is to evaluate the correlation of the separating force and hardness concerning the timing of harvesting, maturity, and variety. Thus, the optimal time for harvesting ripe L. barbarum can be determined to enhance the quality of selectively mechanized harvesting of this fruit. The experiment was conducted in a L. barbarum plantation located in Qinghai Province during the 2023 harvest period. Two occasions were studied focusing on the primary cultivars Ningqi No. 1 and Ningqi No. 7, examining the three ripening stages of L. barbarum harvested at various times throughout the day. The finding of this study showed that the separation force and hardness of L. barbarum fruits were influenced by the harvesting time, the fruit variety, and the level of maturity. The optimal timing for harvesting different types of L. barbarum varies. It was observed that Ningqi No.1 was best to be harvested in the late afternoon and evening (17:00–21:00), whereas Ningqi No.7 was most suitable to be harvested in the morning (7:00–9:00).

Lycium barbarum has been widely planted in arid and semi-arid areas due to its drought-resistant ability, which is of great economic value as a medicinal and edible homology plant. In this study, the metabolome of the L. barbarum variety "Ningqi 7" under different drought stress conditions was compared and analyzed by the non-targeted UPLC-MS (ultra-high performance liquid chromatography with mass spectrometry) technique. The results showed that drought stress significantly decreased the water content of leaves, increased the activity of antioxidant enzymes in plants, and up-regulated the metabolites and pathways involved in osmoregulation, antioxidant stress, energy metabolism, and signal transduction. Under moderate drought (40–45% FC), L. barbarum accumulated osmoregulatory substances mainly through the up-regulation of the arginine metabolism pathway. At the same time, phenylalanine metabolism and cutin, suberine, and wax biosynthesis were enhanced to improve the antioxidant capacity and reduce water loss. However, in severe drought (10–15% FC), L. barbarum shifted to up-regulate purine metabolism and lysine degradation and redistributed energy and nitrogen resources. In addition, vitamin B6 metabolism was significantly upregulated in both groups of stress levels, playing a key role in antioxidant and growth regulation. These observations delineate the metabolic adaptations of L. barbarum "Ningqi 7" in response to drought stress. [ABSTRACT FROM AUTHOR]

This study investigated the effects of Lycium barbarum pulp (LBP) on the properties of mixed dough and gluten protein. The results showed that appropriate addition of LBP (5 %) significantly improved the performance of the dough, promoted the aggregation of gluten protein, enhanced the water binding ability, and delayed the gelatinization of starch during cooking. Compared with the control group, the peak temperature (Tp) of the LBP sample gradually increased from 63.23 °C to 65.56 °C, the expansion force reduced by about 21.56 %, the absolute Zeta potential lowered by about 18.4 %, and the α -helix content and β -folding increased by 32.36 % and 10.23 %, respectively, indicating the more orderly and stable overall structure. However, LBP did not change the crystal configuration of starch and still showed typical type A line diffraction. Moreover, the addition of LBP increased the polyphenol content, which further improved the antioxidant properties and provided the possibility to improve the health potential of the flour.

Abstract Background Goji (Lycium barbarum L.) is a perennial deciduous shrub widely distributed in arid and semiarid regions of Northwest China. It is highly valued for its medicinal and functional properties. Most goji varieties are naturally self-incompatible, posing challenges in breeding and cultivation. Self-incompatibility is a complex genetic trait, with ongoing debates regarding the number of self-incompatible loci. To date, no genetic mappings has been conducted for S loci or other loci related to self-incompatibility in goji. Results We used genome resequencing to create a high-resolution map for detecting de novo single-nucleotide polymorphisms (SNP) in goji. We focused on 229 F1 individuals from self-compatible ‘13–19’ and self-incompatible ‘new 9’ varieties. Subsequently, we conducted a quantitative trait locus (QTL) analysis on traits associated with self-compatibility in goji berries. The genetic map consisted of 249,327 SNPs distributed across 12 linkage groups (LGs), spanning a total distance of 1243.74 cM, with an average interval of 0.002 cM. Phenotypic data related to self-incompatibility, such as average fruit weight, fruit rate, compatibility index, and comparable compatibility index after self-pollination and geitonogamy, were collected for the years 2021–2022, as well as for an extra year representing the mean data from 2021 to 2022 (2021/22). A total of 43 significant QTL, corresponding to multiple traits were identified, accounting for more than 11% of the observed phenotypic variation. Notably, a specific QTL on chromosome 2 consistently appeared across different years, irrespective of the relationship between self-pollination and geitonogamy. Within the localization interval, 1180 genes were annotated, including Lba02g01102 (annotated as an S-RNase gene), which showed pistil-specific expression. Cloning of S-RNase genes revealed that the parents had two different S-RNase alleles, namely S1S11 and S2S8. S-genotype identification of the F1 population indicated segregation of the four S-alleles from the parents in the offspring, with the type of S-RNase gene significantly associated with self-compatibility. Conclusions In summary, our study provides valuable insights into the genetic mechanism underlying self-compatibility in goji berries. This highlights the importance of further positional cloning investigations and emphasizes the importance of integration of marker-assisted selection in goji breeding programs.

This study aimed to develop a method based on hyperspectral imaging (400–1 000 nm) combined with chemometrics to identify the diverse geographical origins of Lycium barbarum fruit. Hyperspectral images of L. barbarum fruit from Ningxia, Gansu, Inner Mongolia, Qinghai and Xinjiang were acquired, and spectral data was extracted from the region of interest (ROI) by threshold segmentation method. Multiple preprocessing methods were employed to eliminate the interference information from the spectra, and the results showed that the discriminant model based on normalized reflectance spectrum (NR) exhibited better performance. Furthermore, the successive projection algorithm (SPA), competitive adaptive reweighted sampling (CARS), particle swarm optimization (PSO), iteratively retaining informative variables (IRIV), and CARS + IRIV were used to select characteristic wavelengths. The results showed that the simplified model based on the wavelengths selected by CARS + IRIV had the best performance. In the models ranging from binary to quintuple classifications, the selected characteristic wavelengths accounted for only 15.6% to 27.7% of the full spectra. The prediction accuracy was 97.7%, 90.9%, 89.2%, and 87.1%, respectively. In addition, a confusion matrix was employed to visualize the optimal simplified classification model in order to intuitively distinguish the classification categories. Satisfactory sensitivity, specificity and Kappa coefficients were obtained in classifying L. barbarum. The results illustrated that hyperspectral imaging technology combined with chemometric methods could effectively identify the geographical origin of L. barbarum and provide crucial technical support for the development of the L. barbarum industry.

Abstract Metabolic syndrome (MetS) is a common disorder involving a cluster of metabolic abnormalities, such as abdominal obesity, hypertension, dyslipidemia, insulin resistance, and atherogenic profile. MetS is characterized by an increase in oxidative stress and a chronic proinflammatory state, which are directly related to the development and progression of this pathology. It has been seen how a healthy lifestyle and good dietary practices are key to improving the different metabolic parameters and, therefore, play a fundamental role in reducing the risk of developing diabetes. The present review focuses on the research evidence related to the therapeutic properties of Lycium barbarum L. in MetS gathered in the last years. Several preclinical studies suggest that L. barbarum extracts are a good dietary supplement for the prevention of cardiovascular diseases in people with MetS. This compound has been used for years in traditional Chinese medicine for the treatment of atrophic gastritis, problems related to the lungs, kidneys, and liver, and as a supplement for eye health. In addition, different in vitro and in vivo studies have been carried out that support the properties attributed to metabolites derived from L. barbarum, such as polysaccharides that have been shown diverse biological activities. In conclusion, L. barbarum extracts have multiple benefits to increase general well‐being and immune function. However, there are a limited number of studies related to effect of L. barbarum in MetS, but they demonstrated effectiveness in the treatment of obesity, diabetes mellitus type 2, and prevention of diabetes mellitus type 2 complication.

In this investigation, the starch-Lycium barbarum complex (CS-LB) was fabricated using corn starch (CS) and Lycium barbarum (LB) through a high-speed shear method. The stability of the guest molecules was also explored. The influence of shear time, rotational speed, and LB to CS mass ratio on Lycium barbarum pigment (LP) content and its stability were investigated. The CS-LB was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). It was found that the content of LP in the product was 0.99±0.03 mg per gram when the shear time was 1.5 hours, the rotational speed was 12000 r/min, and the mass ratio of LB to CS was 3:1. The SEM results illustrated that the products had an agglomerated morphology. The XRD results showed that the crystal domain of starch particles was destroyed and transformed into amorphous structures due to the high-speed shear treatment, but the CS-LP crystalline structure changed into a V-type, which was promoted by the interaction between CS and active components of LB. The FT-IR results showed that the absorption peak at 3421 cm−1 shifted, indicating that CS and LB were bound through hydrogen bonds. The TGA results showed that the thermal stability of the product was also enhanced, with a mass retention rate of 36% at 600 ℃ for the composite. Thus, the CS-LB could be effectively fabricated by high-speed shear treatment. Additionally, it was found that the composite could effectively reduce the effects of temperature, oxygen, and light on the stability of guest molecules in stability experiments. The shelf-life of guest molecules was also extended, enabling them to perform their related functions better.

Background and Objective: Oxidative stress can harm cells, proteins, and DNA and play a role in the aging process. The present study was conducted to determine the impacts of six weeks of Pilates exercises and Lycium barbarum supplement on oxidative stress indices of saliva and body composition of inactive elderly females. Methods: This field trial was carried out on 49 inactive elderly females. The subjects were selected in a purposeful manner and were randomly assigned to 4 groups, including control, supplement, exercise, and exercise plus supplement. The exercise program protocol was implemented for six weeks, three 45-60 minute sessions per week with an intensity of 50-70% maximum heart rate. The Lycium barbarum supplement group used 14 g of supplement daily. Oxidative stress indices of saliva and body composition were compared. The individuals’ physical activity level was determined using the Kaiser Physical Activity Survey (KPAS) and the samples’ health status was specified using the Physical Activity Readiness Questionnaire (PAR-Q). Results: The amount of malondialdehyde had a statistically significant reduction in the exercise plus supplement group compared to the control group, the exercise group, and the supplement group (P

Background Removal of the microbial deposits (plaque and calculus) by performing effective scaling and root planing (SRP) is the fundamental step for managing periodontal disease (gingivitis and periodontitis). Various adjuncts in the form of mouthwash, gels, and toothpaste are also being used as adjuncts to SRP for managing periodontitis. Recently, Lycium barbarum ( L. barbarum), commonly known as goji berry or wolfberry, has gained popularity for managing chronic inflammatory and infectious diseases. However, its efficacy in managing periodontitis has never been explored. Hence the present study aims to evaluate the efficacy of goji berry mouthwash compared to chlorhexidine mouthwash for managing periodontitis. Methods 60 adult participants were divided randomly using computer-generated random sequences into two groups (case group: L. barbarum mouthwash (Males: 16; Female: 14); control group: 0.2% chlorhexidine gluconate mouthwash (Males: 14; Females: 16)). The changes in the gingival index (Gi), plaque index (Pi), bleeding on probing (BOP), clinical attachment loss (CAL), probing pocket depth (PPD), microbial load, and antioxidant levels (protein thiol) in saliva were noted at the baseline, at 15 days and one month. Results A significant reduction in the mean PPD, Pi, and Gi was seen from baseline to one month in both the control (P-value=0.006, 0.027, and 0.036 respectively) and test groups (P-value=0.035, 0.000, and 0.000 respectively). CAL was reduced significantly only in the control group. However, the antioxidant levels (protein thiol) in saliva were significantly increased only in the test group. Conclusion Goji berry mouthwash along with SRP reduced the Gi, Pi, BOP, and PPD in patients with periodontitis. However, no statistically significant difference was noted between the use of goji berry and chlorhexidine mouthwash. Goji berry mouthwash was more effective than chlorhexidine in increasing the antioxidant levels in saliva.

The present study was conducted to determine the impacts of six weeks of Pilates exercises and Lycium barbarum supplement on oxidative stress indices of saliva and body composition of inactive elderly females. Methods: This field trial was carried out on 49 inactive elderly females. The subjects were selected in a purposeful manner and were randomly assigned to 4 groups, including control, supplement, exercise, and exercise plus supplement. The exercise program protocol was implemented for six weeks, three 45-60 minute sessions per week with an intensity of 50-70% maximum heart rate. The Lycium barbarum supplement group used 14 g of supplement daily. Oxidative stress indices of saliva and body composition were compared. The individuals’ physical activity level was determined using the Kaiser Physical Activity Survey (KPAS) and the samples’ health status was specified using the Physical Activity Readiness Questionnaire (PAR-Q). Results: The amount of malondialdehyde had a statistically significant reduction in the exercise plus supplement group compared to the control group, the exercise group, and the supplement group (P<0.05). The amount of malondialdehyde was not statistically significant in the exercise group and the supplement group compared to the control group. The amount of salivary catalase was not statistically significant in the exercise group plus supplement group compared to the control group, the exercise group, and the supplement group. The amount of salivary catalase had a statistically significant increase in the exercise group compared to the control group and the supplement group (P<0.05). The amount of glutathione peroxidase had no statistically significant difference in the exercise plus supplement group compared to the control group but had a statistically significant increase compared to the supplement group (P<0.05). The amount of glutathione peroxidase had a statistically significant increase in the exercise group than in the supplement group (P<0.05). Conclusion: Regular exercise with moderate intensity and Lycium barbarum supplement resulted in improved antioxidant function and body composition in inactive elderly females. [ABSTRACT FROM AUTHOR]

In July 2022, root rot was observed in several goji (Lycium barbarum) orchards located in Qinghai Province, China. Approximately 40% of the goji plants were affected in the orchards. Morphology of fungi isolated from affected plant, phylogenetic analyses, using internal transcribed spacer (ITS), translation elongation factor 1-alpha (TEF), and trichothecene (Tri5) sequences, as well as pathogenicity assays, were conducted to characterize and identify the causing agent of goji root rot. Isolate GQGF1-3 caused typical symptoms of L. barbarum root rot. Fungal colony characteristics and conidium morphology, combined with ITS, TEF, and Tri5 sequences showed that isolate GQGF1-3 was Fusarium sambucinum. This is the first report of F. sambucinum causing root rot of goji. [ABSTRACT FROM AUTHOR]

Self-incompatibility is a widespread genetic mechanism found in flowering plants. It plays a crucial role in preventing inbreeding and promoting outcrossing. The genes that control self-incompatibility in plants are typically determined by the S-locus female determinant factor and the S-locus male determinant factor. In the Solanaceae family, the male determinant factor is often the SLF gene. In this research, we cloned and analyzed 13 S2-LbSLF genes from the L. barbarum genome, which are located on chromosome 2 and close to the physical location of the S-locus female determinant factor S-RNase, covering a region of approximately 90.4 Mb. The amino acid sequence identity of the 13 S2-LbSLFs is 58.46%, and they all possess relatively conserved motifs and typical F-box domains, without introns. A co-linearity analysis revealed that there are no tandemly repeated genes in the S2-LbSLF genes, and that there are two pairs of co-linear genes between S2-LbSLF and the tomato, which also belongs to the Solanaceae family. A phylogenetic analysis indicates that the S2-LbSLF members can be divided into six groups, and it was found that the 13 S2-LbSLFs are clustered with the SLF genes of tobacco and Petunia inflata to varying degrees, potentially serving as pollen determinant factors regulating self-incompatibility in L. barbarum. The results for the gene expression patterns suggest that S2-LbSLF is only expressed in pollen tissue. The results of the yeast two-hybrid assay showed that the C-terminal region of S2-LbSLFs lacking the F-box domain can interact with S-RNase. This study provides theoretical data for further investigation into the functions of S2-LbSLF members, particularly for the identification of pollen determinant factors regulating self-incompatibility in L. barbarum.

The characterization of the PYL/RCAR ABA receptors in a great deal of plant species has dramatically advanced the study of ABA functions involved in key physiological processes. However, the genes in this family are still unclear in Lycium (Goji) plants, one of the well–known economically, medicinally, and ecologically valuable fruit crops. In the present work, 12 homologs of Arabidopsis PYL/RCAR ABA receptors were first identified and characterized from Lycium (L.) barbarum (LbPYLs). The quantitative real–time PCR (qRT–PCR) analysis showed that these genes had clear tissue–specific expression patterns, and most of them were transcribed in the root with the largest amount. Among the three subfamilies, while the Group I and Group III members were down–regulated by extraneous ABA, the Group II members were up–regulated. At 42 °C, most transcripts showed a rapid and violent up–regulation response to higher temperature, especially members of Group II. One of the genes in the Group II members, LbPYL10, was further functionally validated by virus–induced gene silencing (VIGS) technology. LbPYL10 positively regulates heat stress tolerance in L. barbarum by alleviating chlorophyll degradation, thus maintaining chlorophyll stability. Integrating the endogenous ABA level increase following heat stress, it may be concluded that LbPYL–mediated ABA signaling plays a vital role in the thermotolerance of L. barbarum plants. Our results highlight the strong potential of LbPYL genes in breeding genetically modified L. barbarum crops that acclimate to climate change. [ABSTRACT FROM AUTHOR]

In this investigation, the starch-Lycium barbarum complex (CS-LB) was fabricated using corn starch (CS) and Lycium barbarum (LB) through a high-speed shear method. The stability of the guest molecules was also explored. The influence of shear time, rotational speed, and LB to CS mass ratio on Lycium barbarum pigment (LP) content and its stability were investigated. The CS-LB was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). It was found that the content of LP in the product was 0.99±0.03 mg per gram when the shear time was 1.5 hours, the rotational speed was 12000 r/min, and the mass ratio of LB to CS was 3:1. The SEM results illustrated that the products had an agglomerated morphology. The XRD results showed that the crystal domain of starch particles was destroyed and transformed into amorphous structures due to the high-speed shear treatment, but the CS-LP crystalline structure changed into a V-type, which was promoted by the interaction between CS and active components of LB. The FT-IR results showed that the absorption peak at 3421 cm-1 shifted, indicating that CS and LB were bound through hydrogen bonds. The TGA results showed that the thermal stability of the product was also enhanced, with a mass retention rate of 36% at 600 °C for the composite. Thus, the CS-LB could be effectively fabricated by high-speed shear treatment. Additionally, it was found that the composite could effectively reduce the effects of temperature, oxygen, and light on the stability of guest molecules in stability experiments. The shelf-life of guest molecules was also extended, enabling them to perform their related functions better. [ABSTRACT FROM AUTHOR]

Lycium barbarum, known as goji berry or wolfberry, is a fruit long associated with health benefits, showing a plethora of effects ranging from antioxidant, anticancer, anti-inflammatory, and immunomodulatory effects. Its potential is attributed to the significant presence of polysaccharides, glycopeptides, polyphenols, flavonoids, carotenoids, and their derivatives. These compounds effectively counteract the action of free radicals, positively influencing cellular balance and intracellular signaling, contributing to overall cell health and function acting on multiple molecular pathways. Several fractions extracted from goji berries demonstrate antitumor properties, particularly effective against breast cancer, without showing cytotoxic effects on normal human cells. Hence, the review explored the fundamental traits of bioactive elements in Lycium barbarum and their potential in cancer treatment and, specifically, breast cancer. It focused on elucidating wolfberry's influenced biochemical pathways, its synergism with anticancer drugs, and its potential to alleviate the side effects associated with existing cancer treatments.

Wolfberry, also known as goji berry or Lycium barbarum, is a highly valued fruit with significant health benefits and nutritional value. For more efficient and comprehensive usage of published L. barbarum genomic data, we established the Wolfberry database. The utility of the Wolfberry Genome Database (WGDB) is highlighted through the Genome browser, which enables the user to explore the L. barbarum genome, browse specific chromosomes, and access gene sequences. Gene annotation features provide comprehensive information about gene functions, locations, expression profiles, pathway involvement, protein domains, and regulatory transcription factors. The transcriptome feature allows the user to explore gene expression patterns using transcripts per kilobase million (TPM) and fragments per kilobase per million mapped reads (FPKM) metrics. The Metabolism pathway page provides insights into metabolic pathways and the involvement of the selected genes. In addition to the database content, we also introduce six analysis tools developed for the WGDB. These tools offer functionalities for gene function prediction, nucleotide and amino acid BLAST analysis, protein domain analysis, GO annotation, and gene expression pattern analysis. The WGDB is freely accessible at https://cosbi7.ee.ncku.edu.tw/Wolfberry/. Overall, WGDB serves as a valuable resource for researchers interested in the genomics and transcriptomics of L. barbarum. Its user-friendly web interface and comprehensive data facilitate the exploration of gene functions, regulatory mechanisms, and metabolic pathways, ultimately contributing to a deeper understanding of wolfberry and its potential applications in agronomy and nutrition.

Lycium barbarum contains a variety of phytochemicals, primarily polysaccharides, and other potent compounds. L. barbarum is a plant that has several uses in contemporary society, including food processing and everyday eating. However, through traditional processing methods the medicinal or edible value of L. barbarum cannot be fully exploited, to further improve the utilisation rate of L. barbarum and enrich the variety of L. barbarum market. The L. barbarum compound beverage, which uses L. barbarum as its primary ingredient, was created through a series of trials, including the creation of tea beverage recipes and research on the most suitable content of stabilisers, flavouring agent formulations and so on. In addition, several validation tests, including those involving hypoglycaemic and lipid-lowering were conducted. The results indicated that 0.1 g mL−1 stabiliser CMC-Na, 0.2 g mL−1 erythritol, 3 g mL−1 citric acid, 8% L. barbarum juice, and 6% chrysanthemum tea cold brew extract were the best combinations for food additive formulations. Additionally, compound beverages have hypoglycemic and lipid-lowering effects. In conclusion, the research and development of L. barbarum compound beverages can not only increase the rate at which L. barbarum is utilised but also offer fresh ideas for the research and development of L. barbarum as they transition from cash crop agricultural products to market-oriented standardised processed products.

AbstractThe aim of the present study was to identify agents that reduce the anthracyclines-induced cardiovascular and renal damage and have the potential to enhance their therapeutic effects. Three fractions of Lycium barbarum (Goji berry), pectin-free, polysaccharide and a combination of the two (1:1, w/w), were tested on rat models of doxorubicin (DOX)-induced cardio- and nephrotoxicity. They were administered p.o. as doses of 2 mg/kg. DOX was applied at a cumulative dose of 20 mg/kg (i.p.). Different biomarkers for cardiotoxicity (creatine kinase, creatine kinase-MB fraction, aspartate aminotransferase, lactate dehydrogenase), nephrotoxicity (creatinine, blood urea nitrogen, uric acid) and the serum potassium levels were evaluated. Histological analysis of hearts and kidneys was performed. The male Wistar rats treated only with DOX showed a drastic increase in all biomarkers for toxicity. Meanwhile, in all cohorts receiving simultaneously any of the plant fractions, the biomarkers for heart and kidney tissue damage were significantly reduced (p

Objective To determine the content of sulfur dioxide (SO2) in lycium barbarum in farmland and supermarkets and its risk difference to consumers. Methods The sulfur dioxide content was determined by atomic fluorescence spectrophotometer based on the principle that sulfite, ammonium salt and phthalalde-hyde formed fluorescent substances under neutral or weakly acidic conditions. Hazard quotient method was used to calculate the possible health risks of SO2 in lycium barbarum. Results Sulfur dioxide was detected in 43. 75% and 80.00% of the samples from farmland and supermarkets, respectively, but the content of all samples were lower than the standard of the 2020 edition of the Chinese Pharmacopoeia. The content of sulfur dioxide in lycium barbarum from two sources was significantly different (P<0.05). The average health risk of SO₂ from lycium barbarum in farmland and supermarket were 1. 86×10-4 and 1.06×10-3 respectively, with no significant health risk to consumers. Conclusion There are significant differences in the content of sulfur dioxide between farmland and supermarket, and the health risks caused by SO2 are also different, but the content and risk value of SO2 are acceptable in general.

Drought is a persistent challenge for horticulture, affecting various aspects of fruit development and ultimately fruit quality, but the effect on nutritional value has been under-investigated. Here, fruit quality was studied on six tomato genotypes and one goji cultivar under deficit irrigation (DI), from fruit composition to in vitro bioaccessibility of carotenoids. For both species, DI concentrated most health-related metabolites in fresh fruit. On a dry mass basis, DI increased total phenolic and sugar concentration, but had a negative or insignificant impact on fruit ascorbic acid, organic acid, and alcohol-insoluble matter contents. DI also reduced total carotenoids content in tomato (-18.7% on average), especially β-carotene (-32%), but not in goji berry DW (+15.5% and +19.6%, respectively). DI reduced the overall in vitro bioaccessibility of carotenoids to varying degrees depending on the compound and plant species. Consequently, mixed micelles produced by digestion of fruits subjected to DI contained either the same or lesser quantities of carotenoids, even though fresh fruits could contain similar or higher quantities. Thus, DI effects on fruit composition were species and genotype dependent, but an increase in the metabolite concentration did not necessarily translate into greater bioaccessibility potentially due to interactions with the fruit matrix.

The recognition of pollen and pistil in the self-incompatibility process is generally determined by the interaction between the pollen S gene and pistil S gene located at the S locus. However, the regulatory mechanism of self-incompatibility in goji remains unknown. In this study, we used the self-compatible strain '13–19' and self-incompatible strain 'xin9' from Ningxia as parents to create an F1 hybrid population. Reciprocal cross-pollination was performed within the same plant to evaluate the self-compatibility of the parents and F1 progeny. The parents and progeny were subjected to whole-genome resequencing, and mixed pools of DNA were constructed using 30 self-compatible and 30 self-incompatible individuals. Association analysis using the SNP-index method and Euclidean distance was employed to identify the key candidate region of the S locus. The candidate region was further annotated using the Swiss-Prot database to identify genes within the region. Additionally, transcriptome sequencing data from different organs/tissues, as well as from pistils of self-compatible and self-incompatible strains at control (0 h), short (0.5 h), medium (8 h), and long (48 h) time points after self-pollination and cross-pollination, were analyzed to assess differential gene expression and screen for self-compatibility-related loci. Specific primers were designed for PCR amplification to determine the S-RNase genotypes of the extreme parents. The results revealed that the S locus in goji is located within a 32.2 Mb region on chromosome 2 that contains a total of 108 annotated genes. Differential expression analysis showed that ten genes, including Lba02g01064, were specifically expressed in stamens, with four of them annotated as F-box genes, potentially serving as determinants of self-compatibility in stamens. Lba02g01102 was exclusively expressed in pistils and annotated as an S-RNase gene, likely involved in self-compatibility. The expression of Lba02g01102 in pistils decreased after self-pollination and cross-pollination. Six candidate genes exhibited significant changes after self-pollination and cross-pollination. Both parents and progeny carried two S-RNase alleles, and the S-RNase genotypes showed a significant correlation with self-compatibility, with the self-compatible progeny containing the S8-RNase allele. The identification of the S locus in goji provides molecular markers for future marker-assisted breeding and offers genetic resources for studying the mechanism of self-incompatibility in goji, thus contributing to the improvement of goji varieties.

Introduction: Goji berry (Lycium barbarum L.) is a famous edible and medicinal herb worldwide with considerable consumption. The recent cultivation of goji berries in the Daodi region was seriously reduced due to increased production costs and the influence of policy on preventing nongrain use of arable land in China. Consequently, production of Daodi goji berry was insufficient to meet market demands for high-quality medicinal materials. Searching for regions similar to the Daodi region was necessary. Methods: The MaxEnt model was used to predicted the current and future potential regions suitable for goji berry in China based on the environmental characteristics of the Daodi region (including Zhongning County of Zhongwei prefecture-level city, and its surroundings), and the ArcGIS software was used to analyze the changes in its suitable region. Results: The results showed that when the parameters were FC = LQHP and RM = 2.1, the MaxEnt model was optimal, and the AUC and TSS values were greater than 0.90. The mean temperature and precipitation of the coldest quarter were the most critical variables shaping the distribution of Daodi goji berries. Under current climate conditions, the suitable habitats of the Daodi goji berry were 45,973.88 km², accounting for 0.48% of China's land area, which were concentrated in the central and western Ningxia Province (22,589.42 km²), and the central region of Gansu Province (18,787.07 km²) bordering western Ningxia. Under future climate scenarios, the suitable area was higher than that under current climate conditions and reached the maximum under RCP 6.0 (91,256.42 km²) in the 2050s and RCP 8.5 (82,459.17 km²) in the 2070s. The expansion regions weremainly distributed in the northeast of the current suitable ranges, and the distributional centroids were mainly shifted to the northeast. The moderately and highly suitable overlapping habitats were mainly distributed in Baiyin (7,241.75 km²), Zhongwei (6,757.81 km²), and Wuzhong (5, 236.87 km²) prefecture-level cities. Discussion: In this stduy, MaxEnt and ArcGIS were applied to predict and analyze the suitable habitats of Daodi goji berry in China under climate change. Our results indicate that climate warming is conducive to cultivating Daodi goji berry and will not cause a shift in the Daodi region. The goji berry produced in Baiyin could be used to satisfy the demand for high-quality medicinal materials. This study addresses the insufficient supply and guides the cultivation of Daodi goji berry. [ABSTRACT FROM AUTHOR]

Goji berry (Lycium barbarum L.) is a traditional Chinese herbal medicinal plant that is extensively cultivated in the arid and semiarid regions of northwest China. In this study, a novel cytorhabdovirus, tentatively named “goji cytorhabdovirus A (GCVA),” was identified from the goji berry plant exhibiting leaf crinkle symptoms through high-throughput sequencing (HTS). GCVA contains a linear, negative sense single-stranded RNA genome of 14,812 nucleotides and encodes six open reading frames in the order of 3′ leader-N-P-P4-M-G-L-5′ trailer. The genome of GCVA shares the highest nucleotide (nt) identity of 65.80% (16% query coverage) with yerba mate virus A (YmVA) (NC_076472). The N and L proteins also share low amino acid (aa) identities (<35.42 and  <  41.23%, respectively) with known cytorhabdoviruses. Typical features of the viruses in the genus Cytorhabdovirus include a highly conserved consensus sequence in the intergenic regions and extensive complementation of the 5′ non-coding trailer and the 3′ leader. These features were also found in GCVA. These data in combination with a phylogenetic analysis that was based on the aa sequences of the N and L proteins support the proposal that GCVA is a new species in the genus Cytorhabdovirus.

The introduction of the Lycium barbarum (LbL) plant variety to the Republic of Armenia and Artsakh, considering soil and climate conditions along with phytotechnology of cultivation, resulted in the preservation of its growth and development stages without significant alterations. The plant successfully formed fruits and maintained biochemical content typical of its natural habitat. This suggests that the flora could benefit from the addition of this new, promising plant species, which possesses medicinal and preventive properties, nutritional value for both humans and animals, and potential for enhancing ecological environments through various means such as greening of bare slopes, ornamental gardening, and roadside plantings. Furthermore, LbL exhibits frost resistance, drought resistance, and low agrochemical requirements for soil. The discovery of germanium in the biomass of LbL fruits and leaves, and its correlation with environmental and cultivation conditions, implies that the concentration of this anti-tumor element in the plant material can be regulated.

Lycium barbarum is widely distributed in China and used as a traditional Chinese medicine herb to treat dizziness, abdominal pain, dry cough, headache and fatigue. Several studies have examined the endophytes of L. barbarum from northwest China; however, few have focused on that from eastern China. The objective of this study was to isolate and determine the endophytic fungi of L. barbarum from Shandong province, as well as to obtain and identify active secondary metabolites from the endophytes. In this study, 17 endophytic fungi were isolated from L. barbarum and denoted as GQ-1 to GQ-17, respectively. These fungi were further classified into ten genera based on the morphological and ITS identification. The crude extracts of these fungi were obtained by using liquid fermentation and EtOAc extraction, and their antibacterial, cytotoxic, and antioxidant activities were evaluated. The results showed that GQ-6 and GQ-16 exhibited high inhibitory activity; GQ-6 and GQ-9 showed high cytotoxic activity and GQ-5 exhibited high scavenging capability for DPPH free radicals. Additionally, Cladosporium sp. GQ-6 was used to investigate the secondary metabolites. The crude extracts were purified by using column chromatography, reverse column, and liquid chromatography, and four monomeric compounds were identified, including two known compounds (α-acetylorcinol (1) and cladosporester B (2)) and two new compounds (cladosporacid F (3) and cladosporester D (4)). The anti-fungal and antibacterial activities of these compounds were confirmed, but no cytotoxic activity was observed. In conclusion, endophytic fungi of L. barbarum from eastern China can serve as a potential source of active natural products with antibacterial and antioxidant properties. [ABSTRACT FROM AUTHOR]

To understand the structure and diversity of fungal and bacterial communities in root tissues and rhizosphere soil of Lycium barbarum plants infested with root rot, root tissues and rhizosphere soil samples of Lycium barbarum infested with root rot in Qaidam region were analyzed using high-throughput sequencing technology. The results showed that bacterial species were slightly more abundant in soil than that in root tissue, and fungal diversity and abundance were not significantly different between soil and root tissue samples. At phylum level, Proteobacteria and Bacteroidetes had higher abundance in bacterial communities, and Ascomycota and Basidiomycota had higher abundance in fungal communities. At genus level, Pseudomonas was dominated in bacteria, and Cladosporium and Mortierella were dominated in fungi. The correlation analysis showed that bacteria were more different between root tissue and soil samples, and fungi were better correlated in root tissue and soil samples. Both Cladosporium and Mortierella were significantly upregulated in the root system and soil, which assumed to be associated with the pathogenesis of root rot of Lycium barbarum.
