泛素化在植物抗病中的作用

The role of ubiquitination in plant disease resistance

摘要:

泛素化作为植物体内一种广泛存在的调控细胞反应的机制，参与调控植物抗病反应。本文综述了泛素化系统在植物抗病反应中的功能及作用机制，重点介绍了CRLs型E3泛素连接酶和RING/U-box型E3泛素连接酶如何参与调控植物抗病信号途径，以及病原物通过效应蛋白和毒性因子调控植物抗病性的分子机理，为阐明植物抗病机理和植物病害防治方法提供 参考。

Abstract:

Ubiquitination, as a regulating mechanism of cell reactions, exists extensively in plant and is involved in regulating plant disease resistance. This paper reviewed the function and mechanism of ubiquitination system in regulating plant disease resistance. Particularly, we mainly introduced how CRLs and RING/U-box type E3 ubiquitin ligases mediate plant disease resistance signaling and the molecular mechanism of regulation in plant disease resistance through effectors and virulent factors of pathogens. This paper provides reference for illustrating the mechanism of plant disease resistance and controlling the plant diseases.
