青枯菌致病机理及作物抗青枯病研究进展

Advances in Pathogenesis of Ralstonia solanacearum and Crops Resistance to Bacterial Wilt

摘要:

青枯菌(Ralstonia solanacearum)是引起植物青枯病的病原细菌。青枯菌通过T3S(Ⅲ型分泌系统)、T2S(II型分泌系统)等分泌系统将多种毒性因子输送到胞外使寄主植物致病。转基因抗病、培育抗性品种和生物防治是防治青枯病的主要途径。

Abstract:

Bacterial wilt was caused by Ralstonia solanacearum. The Type III secretion system (T3S ) and TypeⅡsecretion system (T2S ) that directly translocated effector proteins into the host cells were essential for the development of disease. There were several ways to improve disease resistance of crops to bacterial wilt, such as, transgenic technology, breeding resistant cultivars, biocontrol, and so on.
