由真菌、细菌和病毒引起的水稻病害是制约水稻可持续发展的主要因素之一。全球生产。利用抗病品种被认为是控制水稻病害最经济有效的方法。在过去的十年中，对稻瘟病菌和水稻白叶枯病菌的抗性基因已有十几个。已经克隆出了稻种。其中大约一半编码核结合位点(NBS)和富含亮氨酸重复序列(LRR)的蛋白，这是最常见的克隆植物抗性基因类型。有趣的是，其中四个基因编码了在其他植物中未发现的新蛋白，这表明水稻防御反应可能涉及独特的机制。本文综述了水稻抗病基因的克隆和鉴定的最新进展，并对水稻抗病基因的功能和进化及其与病原菌无毒基因的相互作用进行了深入的分子分析。
Rice diseases caused by fungi, bacteria and viruses are one of the major constraints for sustainable rice (Oryza sativa L.) production worldwide. The use of resistant cultivars is considered the most economical and effective method to control rice diseases. In the last decade, a dozen resistance genes against the fungal pathogen Magnaporthe grisea and the bacterial pathogen Xanthomonas oryzae pv. oryzae have been cloned. Approximately half of them encode nuclear binding site (NBS) and leucine rich repeat (LRR)-containing proteins, the most common type of cloned plant resistance genes. Interestingly, four of them encode novel proteins which have not been identified in other plant species, suggesting that unique mechanisms might be involved in rice defense responses. This review summarizes the recent advances in cloning and characterization of disease resistance genes in rice and presents future perspectives for in-depth molecular analysis of the function and evolution of rice resistance genes and their interaction with avirulence genes in pathogens.
