摘　要：

摘　要：RRS1是被发现的第一个青枯病抗性基因，能介导多个Ralstonia solanacearum小种的广谱抗性反应，也是至今第一例依赖NDR1蛋白的TIR-NBS-LRR类R基因。该文综述了目前分子机制研究最为详尽的拟南芥抗青枯病基因RRS1的克隆、功能和表达作用模式的研究进展，对其他作物青枯病抗性的分子机理研究提供科学的依据和启示。

Abstract:

Abstract: RRS1 was the first gene of resistance to Ralstonia solanacearum found in Arabidopsis thaliana， which confers broad-spectrum resistance to several strains of R. solanacearum. It was also the first R gene of the TIR-NBS-LRR subclass， depended on NDR1 protein. In this paper， we review the cloning， function and expressive model of RRS1 in A. thaliana， and hope to provide the science evidence and useful enlightenment for the molecular mechanism research of resistance to R. solanacearum in other crops.
Key words: RRS1; resistance to Ralstonia solanacearum; Arabidopsis thaliana
