Fig. 6From: Quick selenium accumulation in the selenium-rich rice and its physiological responses in changing selenium environmentsA working model of the uptake and assimilation of Se in the Se-rich rice. The uptake of soil selenate (SeO32−) stimulates and relies on the expression of two transporter genes in roots, initiating a quick response to internalize Se gradually from the root, stem, leaf and husk to the grain, resulting in red-colored rice by increasing the content of anthocyaninBack to article page
