摘要:

为了更好的防控稻瘟病的发生,为水稻育种工作和新药研发提供科学依据,深入了解稻瘟病菌(Magnaporthe oryzae)与水稻相互作用的机制是非常必要的。本文归纳了稻瘟病菌侵染水稻的机制、水稻对稻瘟病菌侵染的信号识别及其下游反应以及识别后诱导水稻产生的防御反应机制,分析了水稻防御相关基因的表达调控以及利用分子育种手段提高水稻抗病性的相关策略。稻瘟病菌侵染水稻后,植株会通过细胞壁加厚、病程相关蛋白表达以及病原菌侵入位点细胞程序性死亡等系统免疫反应来抵御稻瘟病菌的侵染;因此指出通过基因工程手段诱导植物发生免疫反应来抵御稻瘟病菌的危害具有重要的现实意义,也是防治病害最有效和最经济的方法;而且,作为研究病原菌—植物互作的模式系统,深入了解稻瘟病菌与水稻的互作机制,也为通过诱导水稻防御基因的表达来防治其他重要真菌性病害提供了科学依据。

Abstract:

To better prevent and control the occurrence of rice blast and provide the scientific basis for rice breeding and drug discovery, it is very necessary to explore the mechanism of interaction between Magnaporthe oryzae and rice. In this paper, the mechanism of M. oryzae infecting rice, the signal recognition and downstream response of rice to M. oryzae infection and the defense response mechanism induced by the fungi were summarized, and the expression and regulation of defense-related genes in rice and the molecular breeding strategies for improving rice disease resistance were analyzed. After M. oryzae infection, rice plant could resist the infection by self-defensive systemic response, such as thickening cell wall, expression of pathogenesis-related proteins and programmed cell death at the invasion site of M. oryzae, etc. It is pointed out that using genetic engineering means to induce plant immune response to resist the harm of M. oryzae has important practical significance, and it is also the most effective and cost-optimal method to control rice blast. Moreover, as a model system to study the pathogen-plant interaction, deeply understand the interaction mechanism between M. oryzae and rice can provide a scientific basis for the prevention and control of other important fungal diseases by inducing the expression of rice defense genes.
