Abstract To efficiently counteract pathogens, plants rely on a complex set of immune responses that are tightly regulated to allow the timely activation, appropriate duration and adequate amplitude defense programs. The coordination plant response is known require activity ubiquitin/proteasome system, which controls stability proteins in eukaryotes. Here, we demonstrate N-end rule pathway, subset regulates against wide range bacterial fungal pathogens model Arabidopsis thaliana . We show this pathway positively biosynthesis plant-defense metabolites such as glucosinolates, well phytohormone jasmonic acid, plays key role immunity. Our results also suggest arginylation branch timing program pathogen Pseudomonas syringae AvrRpm1.
