Abstract:

SUMOylation is a highly-conserved post-translational modification in eukaryotes. Under the synergistic work of the SUMOylase system, mature SUMO can covalently target to the lysine residue in substrate proteins in the form of iso-peptide bonds. The SUMOylation is highly dynamic and can regulate various biological processes by affecting target proteins'stability, activity, localization, etc. The conjugated SUMO molecular can be removed from its targets by SUMO proteases and re-enter the SUMO catalytic cycle. Reports indicate that SUMOylation is involved in stress response, growth, and flowering. In this review, we briefly summarize the current processes of the plant SUMOylation pathway and discusses the identification of SUMO tragets by biochemistry and proteomics strategies.

Key words: SUMOylation, growth and development, stress, proteomics
