摘要：

水稻白叶枯病是一种由革兰氏阴性黄单胞菌属病原细菌——稻黄单胞菌（Xanthomonas oryzae pv.oryzae,Xoo）引起的细菌性病害，严重影响水稻的产量和品质。该病是全球性水稻病害，在我国发生范围广，其病原菌具有传播迅速和易突变的特性。本文首先概述了水稻白叶枯病抗性基因的遗传模式，进而详细介绍了抗性基因的挖掘进展以及基因编辑技术在抗病育种中的应用，最后归纳了水稻抗白叶枯病的遗传机制，并对抗病基因的深入挖掘、功能解析及其在育种中的应用前景进行了展望，以期为水稻白叶枯病抗病育种及相关遗传机制研究提供参考。

Abstract:

Rice bacterial blight, caused by the Gram-negative bacterium Xanthomonas oryzae pv. oryzae(Xoo), is a bacterial disease that affects rice worldwide, significantly reducing both yield and quality. This disease is widespread in China, and its pathogen is characterized by rapid transmission and high mutability. This paper begins by outlining the inheritance patterns of resistance genes against rice bacterial blight. It then details recent advances in the identification of these resistance genes and the application of gene editing technology in breeding for blight resistance. Finally, the molecular mechanisms of resistance are summarized, and future prospects for further mining and functional characterization of resistance genes, as well as their utilization in breeding, are discussed. The aim is to provide a reference for in-depth research on resistance breeding and the genetic mechanisms of rice bacterial blight.

Key words: rice, bacterial blight, resistance gene, breeding utilization
