Abstract
The covalent conjugation of SUMO(Small Ubiquitin-related MOdifier) protein to its substrates regulates numerous cellular processes, including protein stability and activity in eukaryotes as well as in plants. In this present review, we summarize biochemical aspects of SUMO conjugation and deconjugation and the functions of SUMO and sumoylation-related proteins in Arabidopsis and other plants. In particular, we provide an overview of the roles of the SUMO in widely different biological processes including the ABA response, floral induction, pathogen defense, abiotic stresses and hormone signaling. Furthermore, we explore the possible roles of SUMO in embryo and seed development.
