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.
