摘要/Abstract

摘要： 水稻与稻瘟菌间存在广泛而特异的相互作用，是研究寄主与病原物互作的重要模式系统。无毒基因是病原物遗传因子，能诱发寄主植物产生抗病性，是稻瘟菌与水稻互作最重要的激发子。为寻求稻瘟病防治的新策略，本研究概述了研究稻瘟病菌无毒基因的意义，归纳了抗性基因与无毒基因互作的3种模式，总结了国内外稻瘟病菌无毒基因的克隆及功能研究，探讨了无毒基因在生产上病害流行预测中的应用，指出利用抗性基因与无毒基因的关系对稻瘟菌分类将会更为科学和实用，应进一步加快稻瘟病菌无毒基因的克隆。

Abstract: The specific interaction between rice and Magnaporthe grisea is an important model system for studying the host-pathogen interaction mechanisms. Avirulence genes (Avr) are hereditary factors of pathogen which could induce disease resistance of host plant and are the most important elicitor of the interaction between host and pathogen. In order to find a new way of precaution and cure rice blast, the significance of M. grisea avirulence gene and three modes of interaction between resistance gene and avirulence gene were summarized, and recent research progresses on avirulence gene and molecular cloning and functional analysis of avirulence gene were summarized, and the application in rice blast epidemic and forecast was also been discussed. It pointed that it was more scientific and practical to classify M. grisea by the connection between resistance gene and avirulence gene and should accelerate the process of avirulence gene cloning.
