Biochemical characterization of the Arabidopsis protein kinase SOS2 that functions in salt tolerance.

Plant physiology - 1 Sept 2002

Gong Deming, Guo Yan, Jagendorf Andre T, Zhu Jian-Kang

Abstract excerpt

The Arabidopsis Salt Overly Sensitive 2 (SOS2) gene encodes a serine/threonine (Thr) protein kinase that has been shown to be a critical component of the salt stress signaling pathway. SOS2 contains a sucrose-non-fermenting protein kinase 1/AMP-activated protein kinase-like N-terminal catalytic d...
