摘要： SUMO化（Sumoylation）作为一种广泛存在于真核生物的重要翻译后修饰,在调控植物生长、发育和逆境应答等方面发挥着重要作用。SUMO E3 连接酶具有底物识别和选择的作用,直接促进SUMO蛋白与靶蛋白的结合。目前,在植物中已经鉴定出多种SUMO E3连接酶。综述了SUMO E3连接酶在植物适应干旱、盐害、高/低温、营养元素匮缺和重金属毒害等非生物胁迫过程中的作用,并展望了未来植物SUMO化研究的方向,以期为今后植物SUMO化方面的研究提供参考。

Abstract: As one of the most important post-translational modifications,sumoylation is widely found in eukaryotes and plays essential roles in the regulation of plant growth,development and stress responses. SUMO E3 ligase has the function of recognizing and selecting substrate,thus directly promotes the binding of SUMO protein and target proteins. At present,a variety of SUMO E3 ligases have been identified in plants. Here,we reviewed the roles of SUMO E3 ligases in plant adaptation to abiotic stresses,including drought,high salinity,high/low temperature,nutrient deficiency and heavy metal toxicity and prospected the future research direction in this field,aiming at providing references for future research on sumoylation in plants.

Key words: Sumoylation, E3 ligase, post-translational modification, Abiotic stress adaptation
