摘要
水稻白叶枯病是由黄单胞杆菌水稻变种(Xanthomonas oryzaepv.oryzae Xoo)引起的细菌性病害,发掘、鉴定和利用新抗源是控制水稻白叶枯病的有效途径。白叶枯抗性基因定位和克隆,使分子标记辅助选择和转基因技术在白叶枯抗病育种中发挥了重大作用,也使人们在分子水平对白叶枯病抗性机制有了深刻认识。文章综述了白叶枯病抗性基因定位,克隆以及在育种方面的应用,并对如何利用抗病育种减轻白叶枯病的危害提出了几点建议。
Bacterial blight,caused by Xanthomonas oryzae pv.Oryzae,is the most devastating plant bacterial disease in Asia.Exploration,identification and utilization of new resistant germplasms to rice breeding are the effective pathway to control the disease.Mapping and cloning the resistant genes makes MAS（marker-assisted selection） and transgenic technology play a great role in breeding program for disease resistance and let people have a profound insight on molecular mechanism of resistance to bacterial blight.In this paper,mapping,cloning and application of the genes resisting to bacterial blight were summarized,and also some suggestion was put forward to relieve the damaging extent caused by bacterial blight via utilizing disease resistant breeding program.
