Abstract

Plant immunity consists of two arms: pathogen‐associated molecular pattern (PAMP)‐triggered immunity (PTI), induced by surface‐localized receptors, and effector‐triggered immunity (ETI), induced by intracellular receptors. Despite the little structural similarity, both receptor types activate similar responses with different dynamics. To better understand phosphorylation events during ETI, we employed a phosphoproteomic screen using an inducible expression system of the bacterial effector avrRpt2 in Arabidopsis thaliana, and identifie
