摘　　要：稻黄单胞菌水稻致病变种[Xanthomonas oryzae pv.oryzae(Xoo)]可引起水稻白叶枯病,是水稻病害中最严重的病害之一,其与水稻互作是基因对基因的关系。Xoo基因组测序的完成极大推动了对Xoo基因功能的研究。为此,该文对近几年来Xoo致病性基因的鉴定情况进行统计,并就致病性基因的突变菌株对水稻接种情况和菌株自身变化进行了归纳,较为详细阐述了当前对Xoo无毒基因的鉴定研究状况,为水稻抗白叶枯病育种以及研究致病基因和致病机制提供理论基础。Xanthomonas oryzae pv. oryzae（Xoo） causes bacterial leaf blight which is one of the most serious diseases in rice, and interacts with rice plants in a gene-for-gene manner. The genomie sequences of Xoo has been sequenced which is accelerated a thorough understangding of gene functions. Hereby, identification of pathogenetic genes of Xoo in recent years was summed up to analyze gene function. Mutant strains had been inoculated rice for identifying pathogenicity and variation of themselves were concluded. Moreover, a detailed review on the current knowledge of the identification of avirulence genes was made in order to provide a basis for breading and studying pathogenetic genes and pathogenetic mechanism.
