摘　要：

SUMO化修饰是一种重要的翻译后修饰, 对蛋白的翻译后调控起到重要作用。植物SIZ1是一种SUMO E3连接酶, 在SUMO化的过程中起着关键作用。本文概述了SIZ1的基本结构和功能, 阐述了其在植物响应非生物胁迫如高温、低温、干旱、盐和离子胁迫时所发挥的调节功能, 并展望了植物SIZ1研究中有待解决的问题。

Abstract:

Sumoylation, an essential factor to modulate proteins, is a very important mechanism of post-translation. SIZ1, a SUMO E3 ligase, plays a key role in the sumoylation in plants. This article summarizes the basic structures and functions of SIZ1. Its roles in response to some abiotic stresses such as low temperature, high temperature, drought, salt stresses and nutrient imbalance in plants are also analyzed. In the end, the outlook of the remaining problems of SIZ1 in plants is made.

Key words: sumoylation; SIZ1; SUMO E3 ligase; abiotic stresses
