Protein posttranslational modifications (PTM) are recognized to be important regulators for protein function, activity, localization,and/or stability and are a substantial component in the cells proteome complexity.Among the possible PTMs, the small ubiquitin-related modifiers (SUMO) have long had inferior standing to phosphorylation and ubiquitination.This has been in part due to their diverse functional consequences for the target proteins.In plants, SUMOylation has been found to play a role in DNA repair, chromatin modification/remodeling, transcriptional regulation, RNA metabolism, stress responses, plant immunity,and other processes (Yates et al., 2016;Augustine and Vierstra,2018;Zhao, 2018).Proteomic studies have identified more than 1000 target proteins in the Arabidopsis proteome, underscoring the pivotal role of SUMOylation (Rytz et al., 2018).
