摘要
泛素化修饰由E1、E2和E3完成,在植物抗非生物胁迫中起重要作用。E3连接酶把E1和E2激活的泛素蛋白传递给特异性的底物,从而降解并调控蛋白影响植物抗胁迫能力。植物抗非生物胁迫的E3连接酶主要包括RING-finger和U-box型两大类,本文分别对抗盐、干旱、温度3种胁迫及ABA信号中上述两类E3连接酶作用和机制作了综述,并提出部分有待于研究的问题以供参考。
Ubiquitination is accomplished by E1,E2 and E3,and plays a role in plant resistance to abiotic stress.E3 ligase transmits ubiquitin,activated by E1 and E2,to specific substrates.Consequently,substrate proteins with ubiquitin are degraded and protein quality is controlled to regulate plant response to stress.Two groups of E3 ligases including type RING-finger and U-box play significant roles in plant resistance to abiotic stress.Advances in understanding functions and mechanisms of the above two kinds of E3 ligases under salt,drought,temperature stresses and ABA signaling pathway are summarized.Some future problems are proposed here for reference.
