In the last decade, SUMOylation has emerged as an essential post-translational modification in eukaryotes. In plants, the biological role of SUMO (small ubiquitin-related modifier) has been studied through genetic approaches that together with recent biochemical studies suggest that the plant SUMOylation system has a high degree of complexity. The present review summarizes our current knowledge on the SUMOylation system in Arabidopsis, focusing on the mechanistic properties of the machinery components identified.
