摘要: 水稻白叶枯病由Xanthomonas oryzae pv. oryzae(Xoo)致病菌引起,导致水稻减产甚至绝收。到目前为止,已有30多个白叶枯病抗性基因被发现,其中仅有[STBX]Xa1,Xa21,Xa23,Xa3/Xa26,Xa27,xa5和xa13[STBZ]等基因被克隆。文章概述了其中6个(除Xa[STBX]23[STBZ])已克隆抗病基因的结构、表达产物及其作用机理的研究进展,指出该方面研究存在的问题,分析了原因。

Abstract: The bacterial blight of rice is caused by the pathogenic bacterium Xanthomonas oryzae pv. oryzae(Xoo), which resulted in great loss of rice yield and even led to lose production completely. More than 30 resistance genes had been identified, and only seven genes ([STBX]Xa1, Xa21, Xa23, Xa3/Xa26, Xa27, xa5 and xa13)[STBZ] had been cloned. The structure, encoded protein and action mechanism of the cloned resistance genes, except Xa[STBX]23[STBZ], were reviewed in this paper.[JP]
