DGK5‐mediated phosphatidic acid homeostasis interplays with reactive oxygen species in plant immune signaling

Reactive oxygen species (ROS) and phosphatidic acid (PA) are important second messengers in plant immunity. PA binding to RBOHD, an NADPH oxidase responsible for ROS production, enhances RBOHD stability and promotes ROS production. Distinct phosphorylation of the lipid kinase DGK5 optimizes the PA b...

Description
Summary:Reactive oxygen species (ROS) and phosphatidic acid (PA) are important second messengers in plant immunity. PA binding to RBOHD, an NADPH oxidase responsible for ROS production, enhances RBOHD stability and promotes ROS production. Distinct phosphorylation of the lipid kinase DGK5 optimizes the PA burst in regulating ROS production.
