Expression changes of three genes under sulfur concentrations (0, 6, 12, 24 and 60 g/ per experimental unit: pot) using real-time quantitative PCR (RT-qPCR) analysis. Unlike the other two genes, the allinase (All) gene faces a decrease in gene expression up to the concentration of 18 sulfur and it faces sudden changes in the concentration of 18 to 24 and the level of gene expression increases and then starts a downward trend. The SOD gene is associated with an upward increase in the initial concentrations of sulfur, and then there is a very slow decrease. But gene SiR shows a continuous and slow rate of increasing expression
