Phosphatidic acid induces leaf cell death in Arabidopsis by activating the Rho-related small G protein GTPase-mediated pathway of reactive oxygen species generation.

Abstract excerpt

Phosphatidic acid (PA) level increases during various stress conditions. However, the physiological roles of this lipid in stress response remain largely unknown. In this study, we report that PA induced leaf cell death and elevated the levels of reactive oxygen species (ROS) in the whole leaf and single cells. To further elucidate the mechanism of PA-induced cell death, we then examined whether Rho-related small...
