Rice A20/AN1 zinc-finger containing stress-associated proteins (SAP1/11) and a receptor-like cytoplasmic kinase (OsRLCK253) interact via A20 zinc-finger and confer abiotic stress tolerance in transgenic Arabidopsis plants

ABSTRACT: The inbuilt mechanisms of plant survival have been exploited for improving tolerance to abiotic stresses. We have investigated the subcellular interactions of rice stress-associated proteins (SAPs) using yeast two-hybrid and FRET approaches and found that A20 domain mediates the interaction of OsSAP1 with self, its close homolog OsSAP11, and a rice receptor-like cytoplasmic kinase, OsRLCK253. Such interactions between OsSAP1/11 and with OsRLCK253 occur at nuclear membrane, plasma membrane and in nucleus. Functionally, both OsSAP11 and OsRLCK253 could improve the water-deficit and salt stress tolerance in transgenic Arabidopsis plants via a signaling pathway affecting the expression of several common endogenous genes. The yield in transgenic plants is also protected indicating the agronomic
