Genome-wide identification of serine acetyltransferase (SAT) gene family in rice (Oryza sativa) and their expressions under salt stress.

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.
