Regulation of reactive oxygen species during plant immunity through phosphorylation and ubiquitination of RBOHD

Abstract

During plant innate immunity ROS is produced via the NADPH oxidase RBOHD. Here, Lee et al. show that RBOHD protein abundance is regulated through phosphorylation by the PBL13 receptor-like cytoplasmic kinase and via ubiquitination by PIRE, a newly identified E3 ubiquitin ligase.
