Abstract
Selenium biofortification aims to increase selenium accumulation or bioavailability in edible crops, tackling the global issue of hidden hunger for essential micronutrients. This review examines the vital role of selenium in human health, its interactions within soil-crop systems, and its potential to alleviate abiotic stresses in plants. By utilizing selenorhizobacteria as biotechnological tools, selenium biofortification presents an innovative method for enhancing crop nutrition and quality. The review emphasizes key mechanisms involved in selenium uptake, its function in activating plant antioxidant systems, and its dual role as both a beneficial nutrient and a prooxidant. Furthermore, it explores microbial contributions to selenium mobility and bioavailability, offering practical strategies to bolster crop resilience and productivity. This comprehensive analysis highlights the importance of selenium biofortification in fostering sustainable agriculture and improving global health outcomes.
