Termitomyces albuminosus is a wild edible mushroom with potential as a functional ingredient, yet its effect on tofu quality remains unclear. This study evaluated soy tofu fortified with Termitomyces albuminosus freeze-dried mushroom powder (TMP) at 1.5, 3, and 5% (w/w) using two strategies: direct addition and soybean replacement. The tofu treatments were assessed for yield, colour, texture, microstructure, molecular interactions, rheological behaviour, proximate composition, mineral profile, and antioxidant activity in fresh, cooked, and in vitro digested states. Increasing TMP progressively reduced yield, lightness, hardness, cohesiveness, and chewiness, with greater deterioration under high percentage replacement, associated with dose-dependent protein network coarsening and protein–polysaccharide phase separation; nevertheless, all samples retained viscoelastic gel behaviour (G′ > G″). The 1.5% replacement treatment largely preserved gel structure and texture, suggesting a favourable balance between enrichment and structural quality. The 5% replacement (R5) provided the greatest nutritional gain, significantly increasing calcium (2177.80 vs. 1812.43 mg/kg) and iron (27.07 vs. 20.61 mg/kg) compared to control while maintaining crude protein above 47% (dry basis). Antioxidant activity increased with TMP level and was highest in R5, with bioaccessibility peaking in the intestinal phase. TMP fortification represents a promising strategy for developing nutritionally enhanced tofu with improved mineral composition and antioxidant bioaccessibility. Full article

Herpes simplex virus type 1 (HSV-1) remains a significant pathogen, particularly in immunocompromised patients. The emergence of drug-resistant strains necessitates alternative therapeutic agents. Lentinula edodes (LE), Hypsizygus marmoreus, and Pleurotus eryngii are edible mushrooms with recognized medicinal properties. However, their effects on drug-resistant HSV-1 remain unclear. This study characterized metabolites from high-temperature/high-pressure (121 °C) water extracts of fresh and dried fruiting bodies and evaluated anti-HSV-1 activities using in vitro and in silico approaches. Metabolic profiles were analyzed by electrospray ionization–quadrupole time-of-flight mass spectrometry. Antiviral activity against HSV-1 KOS (wild-type) and HSV-1 dxpiii (drug-resistant) strains was assessed by plaque assays and qPCR. Molecular docking and network pharmacology were performed on candidate compounds. LE extract from dried mushroom tended to show the highest levels of selected major bioactive constituents, along with greater antioxidant activities. All extracts significantly inhibited viral infection and gene expression in both strains. LE extract from dried mushroom modulated the expression of NFKB1 and IL6. Molecular docking analysis revealed that eritanidine showed a predicted binding affinity to HSV-1 DNA polymerase (−7.95 kcal/mol). Additionally, eritanidine, 5′-methylthioadenosine, and 3-indoleacrylic acid were predicted to interact with TNF and MAPK1. Several compounds also demonstrated favorable drug-likeness properties. Overall, these mushroom extracts are promising natural sources of antiviral agents against HSV-1, including drug-resistant variants. Full article

Neolissochilus heterostomus, a cyprinid fish endemic to Yunnan Province, China, is highly valued for both ornamental and edible purposes, yet its wild populations are currently declining and classified as endangered. In this study, we present a chromosome-level genome assembly of N. heterostomus, utilizing the PacBio HiFi and Hi-C strategies. The assembled genome spans 1793.99 Mb and is anchored to 50 chromosomes, comprising a total of 50,203 genes. Genomic features and chromosomal karyotype data recorded in the present study are consistent with an allotetraploid origin for N. heterostomus. Comparative genomics shows that N. heterostomus shares a close phylogenetic relationship with another allotetraploid fish, the common carp Cyprinus carpio. In total, 4687 expanded and 1365 contracted gene families were identified in N. heterostomus. Further enrichment analyses indicated an overrepresentation of metabolism-related pathways among the expanded and positively selected gene families, whereas the contracted gene families were enriched in reproduction- and embryonic development-related pathways. Reproductive observations further indicate that N. heterostomus produces fewer eggs than other cyprinid species characterized by relatively long embryonic development periods (106.1 h; accumulated temperature: 2260.6 °C·h), including common carp, goldfish (Carassius auratus), grass carp (Ctenopharyngodon idella), pond loach (Misgurnus anguillicaudatus), and blunt snout bream (Megalobrama amblycephala). These findings suggest a potential association between metabolism-related genomic features and reproductive traits, although functional validation remains necessary. Overall, this study may offer insights into the polyploidization, metabolic, and reproductive traits of N. heterostomus, thereby providing genomic and biological resources that may support future studies relevant to the conservation and management of this endangered species.

Fruits of edible plants belonging to the Rosoideae subfamily are widely consumed as foods or utilized as herbs by various traditional medicine systems. Although these plants are mostly known for their rich phenolic content, there are only limited studies exploiting the relationship between their phenolic composition and bioactivities. The present study constitutes an exploratory chemical and bioactivity screening of fruits harvested from the following eight wildly grown edible Rosoideae plant species: Rosa canina, Rosa sempervirens, Rosa pulverulenta, Rosa arvensis, Fragaria vesca, Rubus sanctus, Rubus idaeus and Sanguisorba officinalis. In this context, the total phenolic and flavonoid contents of the investigated fruits were determined, and the presence of selected individual phenolic compounds was quantified. In addition, their antioxidant properties were evaluated by applying the ABTS and DPPH• assays, and their antiproliferative properties were assessed against selected tumor cell lines. Finally, the antiviral properties of fruits were investigated against fourteen common viruses. Respective results highlighted ellagic acid as the prevailing phenolic molecule for six investigated species, whereas several extracts displayed varying levels of antioxidant activities and moderate antiproliferative effects in the tested models. Furthermore, most extracts exhibited an inhibitory effect against Influenza viruses A (H1N1 and H3N2) and B, displaying IC₅₀ values ranging from 0.6 to 4 μg/mL, comparable to currently used antiviral agents. Finally, the Rubus idaeus and Rosa canina fruit extracts were active against adenovirus-2. Since the bioactivities determined herein are based on single biological replicates, they are considered an indicative lead that provides an initial basis for prioritizing these edible Rosoideae species for future studies, which will involve a more detailed characterization of their bioactive phenolic constituents and more extensive, replicated biological experiments.

Plant polyphenols possess various biological activities such as antioxidant and antidiabetic activities. Based on the high plant biodiversity in Thailand, selected edible plants were therefore investigated to explore how dietary polyphenols and α-glucosidase-inhibitory activity can contribute to significant control and prevention of type 2 diabetes mellitus (T2DM). Network pharmacology of antidiabetic activity was employed to predict the underlying antidiabetic mechanisms of the phytochemicals identified in the 15 selected edible Thai plants. The results showed that wild guava (Careya arborea Roxb.; CaA) leaf extract presented the highest total phenolic content (TPC). CaA exhibited the highest antioxidant activities in all the assays as a function of its TPC. Moreover, CaA showed the highest inhibitory effect on α-glucosidase activity in the test, with an IC₅₀ of 0.13 µg/mL, being approximately 1600 times more potent than the standard α-glucosidase-inhibitory drug acarbose. Phenolic profile analysis revealed that the CaA leaf extract consisted of gallic acid, caffeic acid, sinapic acid, rutin, and quercetin. The phytochemical contents of CaA strongly contributed to its antioxidant and α-glucosidase-inhibitory activity. In addition to other phytochemicals, the highest contents of the indolamine compounds tryptophan and melatonin were found in malabar spinach (Basella alba L.; BA) and water clover (Marsilea crenata C. Presl; MaC), at 2213.05 and 99.17 ng/g DW, respectively. Network pharmacology on antidiabetic activity exhibited the most relevant pathway involved in the insulin resistance and AGE-RAGE signaling pathways that caused glucose and glycogen synthesis in skeletal muscle, increasing hepatic gluconeogenesis, and reduced glycogen synthesis in the liver. The implication of these findings is that these Thai edible plants have the potential to combat diabetes by inhibiting the function of α-glucosidase. Full article

Edible flowers are important components of traditional food systems and biocultural practices in southern China, yet their ethnobotanical significance remains poorly documented. This study investigated the diversity, traditional uses, and cultural importance of edible flowers in Baise City through semi-structured interviews, market surveys, and field observations with local informants. Quantitative ethnobotanical indices, including the Cultural Food Significance Index (CFSI), Fidelity Level (FL), and Informant Consensus Factor (ICF), were applied to evaluate cultural and medicinal importance. A total of 96 edible flower taxa belonging to 77 genera and 44 families were documented. Most species were native to China, herbaceous in growth form, and collected from wild habitats. Inflorescences were the most commonly utilized floral organs. Edible flowers were used as vegetables, herbal teas, medicinal edible plants, natural food colorants, condiments, desserts, and snack foods. Species such as Emilia sonchifolia (L.) DC., Plantago asiatica L., and Solanum americanum Mill. showed high cultural significance. A total of 64 taxa were recognized as medicinal edible plants, and high ICF values indicated strong agreement among informants regarding ethnomedicinal uses. These findings demonstrate the important roles of edible flowers in local food systems, traditional healthcare, and biocultural heritage, emphasizing their relevance for biodiversity conservation and sustainable food practices.

Foeniculum vulgare Mill. (fennel) is an edible and medicinal plant cultivated worldwide. Owing to its distinctive aroma and diverse biological activities, its essential oils (EOs) have been widely investigated. However, available data predominantly focus on cultivated fennel or commercial EOs, while comprehensive investigations of wild-growing Mediterranean populations—particularly comparisons among different plant parts—remain scarce. In this study, EOs obtained by hydrodistillation from stems, leaves, flowers, and fruits of native Croatian fennel, were chemically characterised using gas chromatography-mass spectrometry (GC-MS), while antimicrobial activity was evaluated using the disc diffusion method against four bacterial strains. Additionally, the volatile profiles of fennel hydrolates were determined by headspace solid-phase microextraction (HS-SPME) and GC-MS analysis. Fennel flowers gave the highest EO yield (1.95%), followed by mature fruits (1.43%), whereas significantly lower yields were obtained from leaves (0.69%) and stems (0.58%). Trans-anethole was identified as the dominant constituent (from 40.96% in stems to 80.71% in fruits), while α-phellandrene predominated in stem EO (42.77%). Hydrolate volatile profiles were more complex—particularly leaf hydrolate, where 29 compounds were identified. The principal constituents were trans-anethole (39.58–57.40%) and fenchone (16.01–28.80%), while the highest content of estragole was observed in fruit hydrolate (6.56%). The EOs demonstrated moderate antimicrobial activity, showing effectiveness exclusively against Escherichia coli, likely attributable to high phenylpropanoid (primarily trans-anethole) and fenchone contents.

Tetrastigma hemsleyanum Diels et Gilg is a high-value edible and medicinal homologous plant, routinely grown under conventional field or greenhouse production systems across Asia. However, mislabeling of conventional products as the rarer (and more expensive) wild version may occur for financial gain. In this study, stable isotopes (δ¹³C, δ¹⁵N, δ²H, and δ¹⁸O) and metal contents (Cr, Cu, Ni, As, Cd, Pb) were used to characterize plant tissues (tuber root, stem, leaf) and corresponding soils originating from simulated-wild-cultivated (WC) and greenhouse-cultivated (GC) pot trials using the same soil. Carbon and nitrogen isotopes served as key indicators for distinguishing GC and WC products. Specifically, δ¹³C values of GC plant tissues were 1.4 to 2.4‰ more positive than those of WC plant tissues (p < 0.05), and δ¹⁵N values in GC tissues were 2.7 to 4.6‰ more positive than δ¹⁵N in WC tissues (p < 0.01). Lower δ¹⁵N values observed in WC products indicate slower nitrogen turnover compared with GC products. Soil metal concentrations had significant differences between the two cultivation systems, but only limited effects on metal bioconcentration factors (BCFs) and translocation factors (TFs) in T. hemsleyanum tissues. Pb and Cd concentrations in root tissues had large differences between cultivation systems, and carbon dynamics in GC plants were more negatively affected by Pb levels in soils. These findings provide the first investigation of T. hemsleyanum grown under different cultivation practices and establish a scientific basis for distinguishing other wild or simulated-wild labeled food and medicinal plant products from conventionally grown products in future studies.

The consumption of wild rodents in certain regions of Southwest China creates a potential interface for zoonotic pathogen exposure, yet the virome composition of edible rodents remains insufficiently characterized. In this study, we performed multi-organ RNA metatranscriptomic analysis of three commonly consumed rodent species (Niviventer andersoni, Berylmys bowersi, and Rattus losea) collected from Guizhou Province, analyzing five visceral organs per species. A total of 1198 viral contigs spanning 37 viral families were identified, revealing diverse viral communities across host species and tissues, with host identity emerging as a key factor shaping virome structure. Sequences related to Seoul virus were detected in the lungs of R. losea, showing high similarity to previously reported strains, and sequences closely related to porcine Rotavirus A were identified in the lung samples of N. andersoni, indicating a close phylogenetic relationship with livestock-associated viruses. While these findings do not confirm active infection or transmission, they may reflect potential environmental exposure or ecological links at the wildlife–livestock interface. Overall, this study provides a baseline characterization of the multi-organ virome of edible rodents and highlights the importance of integrated surveillance and risk assessment within a One Health framework.

The fruits of Lycium chinense are important medicinal and edible resources with multiple bioactive functions, including hepatoprotective, antioxidant, and immunomodulatory effects. Although this species is widely distributed in China and exhibits abundant germplasm resources, systematic evaluations of fruit quality variation among wild germplasm remain limited, restricting the selection and breeding of superior resources. In this study, eight wild germplasm resources of L. chinense were collected from the eastern coastal regions of China, including Liaocheng (LC), Rugao (RG), Dafeng (DF), Suzhou (SZ), Qidong (QD), Dongtai (DT), Jingjiang (JJ), and Sheyang (SY). A total of 29 fruit quality-related traits, including fruit size, flavonoids, soluble sugars, vitamin C, and amino acids, were analyzed. Significant differences were observed among germplasm resources in both fruit size and internal quality. Comprehensive evaluation based on principal component analysis and entropy weight–grey relational analysis indicated that SY and LC ranked highest. SY exhibited smaller fruits but superior nutritional quality, with higher levels of soluble protein, vitamins, and amino acids. In contrast, LC showed larger fruits and higher contents of polysaccharides and total phenolics, along with stronger antioxidant capacity. Overall, SY and LC represent promising germplasm resources for breeding and utilization of L. chinense. Full article

Wild edible fruits play an important role in supporting food security, nutrition, and traditional knowledge systems in rural communities, yet their diversity and uses remain insufficiently documented in many parts of Thailand. This study aimed to investigate the diversity, utilization, and ethnobotanical significance of wild edible fruit species in Kut Chum District, Yasothon Province. Ethnobotanical data were collected through semi-structured interviews and field surveys with local informants, and quantitative indices, including the Cultural Importance Index (CI), Fidelity Level (%FL), and Informant Consensus Factor (ICF), were applied to evaluate species significance and medicinal agreement. A total of 71 species belonging to 33 families were recorded, with most species consumed as fresh fruits and a subset used for medicinal purposes. Several species, such as Irvingia malayana Oliv. ex A.W.Benn., Phyllanthus emblica L., and Syzygium cumini (L.) Skeels exhibited high cultural importance, reflecting their key roles in local diets. High ICF values across therapeutic categories indicated strong consensus in ethnomedicinal knowledge. Additionally, 44 species not used medicinally in the study area were reported as medicinal in other regions, highlighting spatial variation in knowledge systems. These findings emphasize the importance of wild edible fruits as multifunctional resources contributing to food and nutritional security. Integrating culturally important species into conservation and sustainable use strategies may support biodiversity preservation and the continuity of traditional ecological knowledge. Full article

The application of biostimulants is a promising tool for enhancing plant growth and crop quality in the context of sustainable and resilient agricultural production. This study evaluated four microbial biostimulants (IMB1–4) on Sonchus oleraceus L. under field and pot cultivation. Our results indicate that the growing system was a more dominant factor than biostimulants in influencing plant performance. For morphological and growth traits, biostimulants generally had a neutral or negative impact compared with untreated plants, with IMB3 consistently showing the lowest performance. Field-grown plants, especially the untreated ones, excelled in plant weight and leaf count, while pot-grown plants treated with IMB2 and IMB4 achieved higher leaf weight per plant, leaf area, and chlorophyll index (SPAD). Specifically, untreated field plants recorded the highest biomass, whereas IMB2 and IMB4 optimized leaf traits in pots. Biostimulant applications enhanced fat content and energetic value, with IMB1 and IMB2 yielding the highest protein levels. Pot cultivation favored the accumulation of nitrogen, phosphorus, and sodium, while IMB2-treated pot plants proved most effective for maximizing overall nutrient content. The phytochemical profile also varied by system: pot-grown plants yielded higher total phenols, particularly with IMB3, while field-grown plants recorded higher flavonoids, especially with IMB4. Furthermore, untreated or IMB3-treated pot plants exhibited the highest antioxidant activity, significantly outperforming field-grown counterparts. In conclusion, while biostimulants did not improve morphological and growth traits, they significantly enhanced the nutritional and phytochemical quality of S. oleraceus L., particularly in the pot cultivation system, where specific biostimulants (IMB2 and IMB3) resulted in nutrient-dense crops with high antioxidant value.

Lactarius hatsudake is an ecologically and economically significant wild edible mushroom in southern China. To elucidate its population genetic diversity, differentiation, and evolutionary history, we analyzed 172 fruiting bodies from eight geographic populations (AQ, BS, DZ, JS, NC, PT, SG, YX) across seven provinces in the western and eastern regions of southern China using five highly polymorphic simple sequence repeat (SSR) markers. Combined with STRUCTURE clustering, discriminant analysis of principal components (DAPC), unweighted pair group method with arithmetic mean (UPGMA), and analysis of molecular variance (AMOVA), the results revealed high polymorphism across the studied loci (mean PIC = 0.842). A total of 75 alleles were identified, averaging 15 alleles per locus. At the population level, the mean effective number of alleles (Ne) was 4.023, and the mean unbiased gene diversity (uH) was 0.768. The NC population exhibited the highest genetic diversity (uH = 0.796), whereas the BS population showed relatively lower diversity (uH = 0.647). Clustering analyses (STRUCTURE, DAPC, and UPGMA) consistently identified two distinct genetic clusters (K = 2). Cluster I consisted of populations AQ, PT, BS, and SG, while Cluster II was composed of the remaining four populations. Notably, individuals from AQ and NC displayed significant genetic admixture, suggesting a transitional zone. AMOVA revealed that the majority of genetic variation (83%) resided within populations and 17% among populations. Moderate population differentiation (ENA-corrected global Fst = 0.102) and admixture signals suggest non-negligible connectivity among populations. Full article
