Quick selenium accumulation in the selenium-rich rice and its physiological responses in changing selenium environments

Abstract: Background:The element selenium (Se) deficiency is thought to be a global human health problem, which could disperse by daily-supplement from Se-rich food. Increasing the accumulation of Se in rice grain is an approach matched to these nutrient demands. Nonetheless, Se is shown to be essential but also toxic to plants, with a narrow margin between deficiency and toxicity. Notably, the regulatory mechanism balancing the accumulation and tolerance of Se in Se-rich rice plants remains unknown. Results:In this stu… Show more

“…This primary Se absorption difference is due to regulation of transporters resident in the plasma membrane of root cells. Recently, Liang et al (2019) demonstrated that a low concentration of Se in the supply medium induces the expression of OsNIP 2;1 , which may serve as a strong positive regulator of Se transport in rice.…”
