摘　　要：水稻白叶枯病是一种由革兰氏阴性黄单胞菌稻致病变种(Xanthomonas oryzae pv.oryzae,Xoo)引起的细菌性病害,是中国南方稻区常年发生的流行性病害。长期的生产实践证明,挖掘新型抗病基因以及合理利用新的广谱持久抗病品种是防控水稻白叶枯病最为经济、有效和环境友好的途径。阐明水稻对白叶枯病菌的防御机制能为水稻抗病育种奠定理论基础。本文简要概述了水稻白叶枯病的发生和现状,归纳了水稻主效抗病基因、抗病相关基因和感病基因的类型,总结了水稻抵御水稻白叶枯病病原细菌的主要途径,为水稻白叶枯病的绿色防控提供理论依据。Rice bacterial blight(BB)caused by Xanthomonas oryzae pv.oryzae is one of the most devastating rice disease in the world.BB is a prevalent epidemic bacterial disease in southern rice regions in China.It has been proved that the most economical,effective and environmentally friendly strategy for controlling BB is cultivating disease-resistant varieties,while the foundation for BB resistance breeding is to identify and apply new BB resistance genes.Elucidating the defense mechanism of rice against bacterial blight can lay a theoretical foundation for disease resistance breeding of rice.In this paper,the occurrence and current situation of rice bacterial blight were briefly summarized,the major resistance genes,related resistance genes and susceptible genes were overviewed,and the main ways of rice to resist bacterial blight were introduced,which could provide theoretical basis for green prevention and control of rice bacterial blight.
