Abstract

Abstract: Bacterial blight is the most devastating bacterial disease in rice production which seriously influence the yield and quality.Traditional chemical control and biological control have little effect on the disease. Developing resistant cultivars is the most economical, effective and environmentally-friendly means to control the disease. Up till now, 40 resistance genes to bacterial blight have been identified from cultivated rice and wild rice. Among them, 32 genes have been mapped to chromosomes, 9 genes have been cloned. In this paper, mapping, cloning,the molecular characteristics and action mode of the disease resistance genes, together with application of the genes in rice production were summarized, and the future prospects of rice resistance breeding are discussed.

Key words: rice bacterial blight, gene mapping, gene cloning, action mode, resistance breeding

摘要： 白叶枯病是水稻生产上主要的细菌性病害之一，严重影响水稻的产量和品质。传统的化学防治和生物防治法收效甚微，利用抗病基因培育抗病品种是最经济、有效和环保的途径。截至目前，从栽培稻和野生稻中鉴定的抗白叶枯病基因有40个，其中32个已被定位，9个已被分离克隆。本文对这些抗白叶枯病基因的定位、克隆、基因特征和作用方式进行了介绍，重点对这些基因在生产上的应用进行了综述，并对水稻白叶枯病抗病育种做出了展望。
