抗病性是水稻遗传改良的主要目标, 是水稻高产、优质的重要保证。近年来, 水稻的抗病机制研究取得实质性进展, 鉴定并克隆了一批重要的抗性基因。文章综述了这些基因的鉴定、克隆和生物学功能研究进展, 探讨了抗病基因的有效利用。

Improving the disease resistance of rice is a major objective in rice breeding programs, which provides a basic guarantee for the good quality and high yield in rice. Recently, substantial progresses on the research of rice disease resistant mechanism had been made. Some important genes had been identified and cloned. The recent achievements in identification, cloning, and biological function analyses of these genes were summarized and their potential application in breeding was also discussed.
