SGT1基因研究进展及其在橡胶树白粉病抗性中的应用

Research Progress of SGT1 Gene and Its Application Prospect in Powdery Mildew Resistance of Rubber Tree

橡胶树白粉病是影响橡胶树生长和降低胶乳产量的主要叶部病害,其流行病学和化学防控已有研究,但橡胶树抗白粉病的分子作用机制尚不清楚。SGT1是一种高度保守的真核蛋白,通过与多种分子伴侣相互作用激活免疫反应对植物抗病性起着核心作用。本研究从SGT1基因结构特征及其在拟南芥、烟草、小麦等植物中生长发育和逆境胁迫作用机制的研究进展,并对HbSGT1在橡胶树白粉病抗性研究中的应用进行了展望。

Rubber tree powdery mildew is a major foliar disease that affects the growth of rubber trees and reduces rubber production.Its epidemiology and chemical control have been studied,but the molecular mechanism of action of rubber tree resistance to powdery mildew is not yet clear.SGT1 is a highly conserved eukaryotic protein that plays a central role in plant disease resistance by interacting with a variety of molecular chaperones to activate the immune response.The author reviews the progress of research on the structural characteristics of SGT1 genes and their mechanisms of growth and development and the role of stress in Arabidopsis,tobacco and wheat,and provides an outlook on the application of HbSGT1 in the study of powdery mildew resistance in rubber trees.
