Selenium has been shown to significantly enhance crop growth and productivity, particularly under abiotic stress conditions, by improving the yield and nutritional quality of crop plants. The uptake of selenium from the soil is mediated by various root-level transporters, which facilitate its involvement in critical physiological and metabolic pathways. Moreover, selenium contributes to enhanced stress tolerance, highlighting its potential as a crucial element for promoting sustainable agricultural practices. This chapter explores selenium-induced molecular pathways, physiological and metabolic modifications, transcriptomic responses to Se application, its impact on crop yield and the underlying mechanisms of selenium uptake and translocation under abiotic stress conditions in crop plants.

摘要

Selenium has been shown to significantly enhance crop growth and productivity, particularly under abiotic stress conditions, by improving the yield and nutritional quality of crop plants. The uptake of selenium from the soil is mediated by various root-level transporters, which facilitate its involvement in critical physiological and metabolic pathways. Moreover, selenium contributes to enhanced stress tolerance, highlighting its potential as a crucial element for promoting sustainable agricultural practices. This chapter explores selenium-induced molecular pathways, physiological and metabolic modifications, transcriptomic responses to Se application, its impact on crop yield and the underlying mechanisms of selenium uptake and translocation under abiotic stress conditions in crop plants.
