Gas exchange parameters, photosynthetic pigments, sugar accumulation, and total saponin content were measured to assess the effects of CO2 enrichment on photosynthesis, sugar metabolism, and saponin biosynthesis. The e1CO2 treatment significantly increased net photosynthetic rate (by 17.22% at 36 days and 69.62% at 92 days), chlorophyll a content, and soluble sugar, sucrose, and starch accumulation. Key sugar metabolism enzymes, including sucrose phosphate synthase (SPS), also showed enhanced activity. Consequently, underground rhizome total saponins rose significantly by 15.16%. In contrast, e2CO2 initially (36 days) stimulated photosynthesis but lost this effect over prolonged exposure (92 days), with no significant impact on photosynthetic parameters, pigments, or sugar levels. Correlation analysis indicated that rhizome saponin content was positively associated with leaf sucrose levels and sucrose synthase (synthetic direction) activity. These findings suggest that moderate CO2 elevation (e1CO2) enhances P. japonicus photosynthesis and sugar metabolism, driving greater saponin accumulation. However, high CO2 (e2CO2) has transient benefits, with stimulatory effects diminishing over time.","PeriodicalId":54605,"journal":{"name":"Phyton-Annales Rei Botanicae","volume":"95 3","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147877515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the functions and genomic traits of endophytic keystone fungi in plant tissues remain unclear. Via network analysis, this study identified keystone fungi Plectosphaerella (Plec) and Cladosporium (Clad) in roots/leaves of medicinal Panax plants (P. ginseng, P. quinquefolius, P. notoginseng). Both correlated strongly positively with ginsenoside Rd content in respective tissues (ρ > 0.6, p < 0.001). Co-cultivation confirmed their ability to convert ginsenoside Rb1 to Rd, linked to β-glucosidase activity. Whole-genome sequencing/assembly/evolutionary analysis of the two strains elucidated genomic features for their keystone roles and saponin biotransformation. Genome mining found multiple GH3 genes (potential saponin transformers) in both; 11 (Plec) and 5 (Clad) were upregulated by cellobiose. Gene family phylogenetic analysis showed expanded transmembrane transport and environmental response functions. Both also had abundant secondary metabolic gene clusters and secretome genes, linking biotic interaction functions to their keystone roles. In summary, this study shows Panax endophytic keystone fungi can participate in ginsenoside biotransformation and clarifies their genomic traits, offering insights for functional endophytic fungal resource development.","PeriodicalId":54605,"journal":{"name":"Phyton-Annales Rei Botanicae","volume":"95 2","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has attracted much attention due to prominent healthcare and therapeutic effects, but faces problems of adulteration with closely related species and confusion about geographical origins. In this study, multiple technical approaches were employed to identify its genetic characteristics and metabolic differences. Based on DNA barcoding, 20 batches of samples were analyzed. The genetic distances of matK, ITS and psbA-trnH within species were all smaller than those between species, and psbA-trnH along with ITS + psbA-trnH proved most effective in distinguishing botanical sources. With Inter-simple sequence repeat (ISSR) technology, 12 highly polymorphic and reproducible primers were selected from 21, and 189 alleles were detected. Epimedium sagittatum showed distinct genetic diversity. Samples with similar genetic distance and geographical location also tended to cluster together. Eight index components were analyzed, and their contents showed significant differences. The total content ranged from 0.50% to 7.09%, and icariin and epimedin C were identified as potential biomarkers. Integrative analysis revealed that the differences in index components were jointly driven by genetic diversity and ecological factors. Additionally, “mean temperature of driest quarter”, “precipitation seasonality”, and “temperature annual range” were identified as key environmental factors. This study provides a reliable experimental basis for the authenticity and quality evaluation of Epimedium.","PeriodicalId":54605,"journal":{"name":"Phyton-Annales Rei Botanicae","volume":"95 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147878041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically evaluated the combined effects of light intensity (150, 200, 250 μmol/(m2·s)) and calcium supply in the nutrient solution (0.5, 1.0, 1.5 mmol/L) on lettuce morphology, photosynthesis, quality indices, and tipburn incidence. Elevating light from 150 to 200 μmol/(m2·s) significantly enhanced leaf number, area, photosynthetic rate, biomass, and foliar calcium. These gains plateaued at 250 μmol/(m2·s), where tipburn incidence surged to 76.5%. Photosynthetic pigments progressively rose with light intensity. Calcium supply showed limited morphological influence but proved critical under high light (250 μmol/(m2·s)): increasing calcium to 1.5 mmol/L significantly boosted vitamin C and soluble sugars while reducing nitrate accumulation and suppressing tipburn to 12.8%. Elevated calcium also partially compensated for growth and quality limitations under low light through compensatory effects. Results demonstrated light intensity as the dominant factor governing morphogenesis and photosynthetic capacity, these findings establish that coordinated optimization of light and calcium inputs is crucial for simultaneously improving lettuce yield, nutritional quality, and marketability in controlled environments. This study provides both theoretical insights and practical guidance for efficient and safe leafy vegetable cultivation in controlled environments.","PeriodicalId":54605,"journal":{"name":"Phyton-Annales Rei Botanicae","volume":"94 11","pages":"3611-3632"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147879750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the control, EA treatment can reduce the browning degree and rotting rate of strawberry fruit during storage and augment the soluble solid content (SSC). EA treatment can also increase the content of related stuff and enzyme activity in antioxidant systems; the gene expression level of polyphenol oxidase (PPO) in strawberries treated with EA was always down-regulated, correspondingly, the expression of other antioxidant enzyme genes was enhanced. Among the strawberry fruits treated with EA of different concentrations, 300 mg L−1 EA had the best effect in the process of strawberry preservation. The results suggested that the proper concentration of exogenous EA at 300 mg L−1 could maintain strawberries’ quality and enhance the antioxidant system by improving the activities of antioxidative enzymes and the ascorbate-glutathione (AsA-GSH) cycle during storage.","PeriodicalId":54605,"journal":{"name":"Phyton-Annales Rei Botanicae","volume":"93 1","pages":"15-28"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.techscience.com/phyton/online/detail/19675/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
