Abstract: SUMOylation is a crucial post-translational modification in plants, playing a pivotal role in plant immune regulation by mediating substrate protein functions, the activation and transduction of immune signals, and hormonal signaling networks. This review systematically summarizes recent research advances in SUMOylation during plant-pathogen interactions, focusing on the enzymatic cascade mechanisms of the SUMOylation system, the involvement of SUMOylation in plant immune regulation, and the manipulation of the SUMOylation system by pathogen effector proteins. This review aims to decipher the SUMOylation-mediated regulatory network of plant immunity and to provide reference for developing novel disease resistance strategies in crops based on SUMO modification.

Key words: SUMOylation, pathogen, immune signaling, hormonal signaling, effector protein
