摘要
水稻是最重要的粮食作物之一.由革兰氏阴性菌黄单胞杆菌水稻致病变种(Xanthomonas oryzae pv.oryzae,Xoo)引发的水稻白叶枯病是最古老和严重危害水稻安全生产的一种细菌性病害,具有突变性强、传播快和分布广等特点.发掘和鉴定新抗原,利用抗性基因培育抗病品种是防治白叶枯病的有效途径.截至目前,已有49个水稻白叶枯病抗性基因被鉴定,其中42个抗性基因已被定位,包括28个显性基因和14个隐性基因,17个抗性基因已被成功克隆.这些抗性基因的表达与否、或与病原菌表达蛋白的互作是产生抗性的关键.本文对水稻白叶枯病抗性基因的研究和育种应用进展进行了综述,并提出展望,为水稻抗白叶枯病的研究和分子育种提供参考.
Abstract
Rice is one of the most important food crops.Rice bacterial blight caused by Xanthomonas oryzae pv.oryzae(Xoo)is one of the oldest and most serious bacterial diseases that endangers the safe production of rice.The Xoo,which has the characteristics of strong mutability,rapid spread and wide distribution.It is an effective way to control bacterial blight by discovering and identifying resistance genes and breeding resistant varieties with them.Up to now,49 resistance genes related to rice bacterial blight have been identified,among which 42 resistance genes have been located,including 28 dominant genes and 14 recessive genes.17 resistance genes have been successfully cloned.The expression of resistance genes or interactions between resistance genes and proteins expressed by pathogen is the key to induce resistance.In this paper,the research and breeding application progress of rice bacterial blight resistance genes were reviewed and prospects.The aim of this paper is to provide valuable information for the further study and molecular breeding of rice bacterial blight.
