The expression levels of cysteine desulfurase of variety KT30 and variety Defumm-8 first decreased and then increased with the increasing Se concentration; however, expression levels of Se were lower than the control, and expression levels of Se in leaves of variety Luobeiqi increased.
Many studies have proven that cysteine desulfurase (CysD), S-adenosyl-l-Met:l-Met S-methyltransferase (MMT) (Berken et al., 2002), serine acetyltransferase (SAT) (Van Hoewyk et al., 2008), and SeCys methyltransferase (SMT) were also the main genes for plant metabolism and Se accumulation (Berken et al., 2002).
