Background: Heavy metal contamination significantly threatens crop growth and global food security. Understanding plant responses to such stress is crucial developing stress-tolerant crops. This study explores the physiological biochemical of Vigna radiata (L.) R. Wilczek mercury, lead, copper stress, focusing on role soluble sugar accumulation biomass enhancement in conferring heavy tolerance. Methods: Commercially available V. seeds were exposed varying concentrations (50, 150, 300 mg/L) mercurous nitrate, lead chloride under controlled conditions. The germination rates, seedling growth, parameters as protein content analyzed using spectrophotometry statistical methods, including ANOVA. Results: results demonstrated that ion increased dry weight, while all tested metals promoted accumulation. Although inhibited at higher concentrations, exhibited strong tolerance moderate levels. Conclusion: highlights adaptive strategies radiata, soluble-sugar-mediated osmotic adjustment enhanced allocation, which contribute its resilience stress. These findings provide insights for breeding stress-resistant crops managing heavy-metal-contaminated environments.

Isatidis Folium, derived from the dried leaves of Isatis indigotica Fort., has been used for centuries as a traditional Chinese herb with antibacterial and antiviral properties. However, heterogeneity in cultivation conditions climatic variations poses challenges to accurately effectively evaluate its quality. Current quality control methods cannot provide comprehensive effective identification herbal preparation efficacy. This study aimed investigate impact different environmental factors on biosynthesis accumulation medicinal components identify biomarker genes functional proteins associated abiotic stress responses Fort. We proposed evaluating Folium based multi-component quantitative analysis integrating transcriptomic, proteomic, physiological indicators elucidate mechanisms variation. The results revealed that significantly altered levels bioactive constituents, indices, specific proteins. Notably, biological pathways such porphyrin metabolism, photosynthesis, carbon fixation by photosynthetic organisms were implicated phototoxicity within photosystem under stresses. Biological related indole specifically phenylalanine, tyrosine, tryptophan synthesis, alkaloid recognized critical regulatory networks modulating content. Candidate biomarkers HemB, PsbB, RBS2, RIBA2, TRPA, TRPB identified potential deterioration adverse conditions. Based integration chemical multi-omics techniques, new hierarchical scenario was finally proposed, providing research foundation innovation-driven development medicine.
