Bacterial blight is one of the most widely distributed bacterial diseases affecting rice production today.The traditional methods of prevention and treatment are hard to be effective,but studying and grubbing host-plant resistance gene is the most economical,safe,effective,easy and environmentally friendly measure.At present,42 rice leaf blight resistance genes were identified and reported,of which 10 have been cloned.This review summarized recent advances in the research of rice leaf blight resistance genes.%白叶枯病是现今分布广、严重影响水稻生产的细菌病害之一.传统的防治方法很难奏效,而研究并挖掘白叶枯病抗性基因是最经济、安全、有效、易行和环保的措施.目前,被鉴定并报道的水稻白叶枯抗性基因有42个,其中有10个已被分离克隆.综述近些年水稻白叶枯抗性基因的研究应用进展.
