SUMO news: Antagonistic crosstalk among Arabidopsis SUMO isoforms in immune balances/trigger
Plants have been endowed with the ability to tolerate diverse external stress. Several proteins that have been discovered to play a critical part in this adaptation respond quickly to the environmental cues. Post-translational modifications on proteins provide capacity to regulate their functions/fates. This study investigated SUMOylation, the covalent attachment of Small Ubiquitin like modifiers (SUMO) to the unique lysine residue on a target protein.
