| Abstract: |
| Sumoylation is one of the essential post-translational modifications in eukaryotes，and it plays an
important role in various cellular regulatory processes. Sumoylation is a dynamic，reversible cycle，consisted of a series
of biochemical reactions，including SUMO E1 activation，E2 conjugation，E3 ligation and deconjugation of SUMO
substrates catalyzed by ubiquitin-like SUMO-specific proteases. Sumoylation plays key roles in hormone response，
flower development，flowering time regulation，nutrient absorption and environmental adversities. In recent years，
sumoylation has become the new growth point of functional gene research in plants. Following is a brief overview of
the current understanding of sumoylation in Arabidopsis and rice，we first introduce the important components in
the sumoylation pathway，and then review the current progress that SUMO modification regulates plant growth and
development，including the response to signal of hormone and abiotic stress，flower development and flowering time
regulation. Finally，suggestions are presented for future research of sumoylation according to previous studies. It is
expected to provide a basis for better understanding the roles of sumoylation of proteins in plants. |
