dc.description.abstractBackground Assimilation of sulfur to cysteine (Cys) occurs in presence of serine acetyltransferase (SAT). Drought and salt stresses are known to be regulated by abscisic acid, whose biosynthesis is limited by Cys. Cys is formed by cysteine synthase complex depending on SAT and OASTL enzymes. Functions of some SAT genes were identified in Arabidopsis; however, it is not known how SAT genes are regulated in rice (Oryza sativa) under salt stress. Methods and results Sequence, protein domain, gene structure, nucleotide, phylogenetic, selection, gene duplication, motif, synteny, digital expression and co-expression, secondary and tertiary protein structures, and binding site analyses were conducted. The wet-lab expressions of OsSAT genes were also tested under salt stress. OsSATs have underwent purifying selection. Segmental and tandem duplications may be driving force of structural and functional divergences of OsSATs. The digital expression analyses of OsSATs showed that jasmonic acid (JA) was the only hormone inducing the expressions of OsSAT1;1, OsSAT2;1, and OsSAT2;2 whereas auxin and ABA only triggered OsSAT1;1 expression. Leaf blade is the only plant organ where all OsSATs but OsSAT1;1 were expressed. Wet-lab expressions of OsSATs indicated that OsSAT1;1, OsSAT1;2 and OsSAT1;3 genes were upregulated at different exposure times of salt stress. Conclusions OsSAT1;1, expressed highly in rice roots, may be a hub gene regulated by cross-talk of JA, ABA and auxin hormones. The cross-talk of the mentioned hormones and the structural variations of OsSAT proteins may also explain the different responses of OsSATs to salt stress.en_US
