Heterotrimeric G protein mediates ethylene-induced stomatal closure via hydrogen peroxide synthesis in Arabidopsis.

The Plant journal : for cell and molecular biology - 1 Apr 2015

Ge Xiao-Min, Cai Hong-Li, Lei Xue, Zhou Xue, Yue Ming, He Jun-Min

Abstract excerpt

Heterotrimeric G proteins function as key players in hydrogen peroxide (H2O2) production in plant cells, but whether G proteins mediate ethylene-induced H2O2 production and stomatal closure are not clear. Here, evidences are provided to show the Gα subunit GPA1 as a missing link between ethylene and H2O2 in guard cell ethylene signalling. In wild-type leaves, ethylene-triggered H2O2 synthesis and stomatal closure...
