稻瘟病是由真菌 Magnaporthe oryzae 所致, 是世界上最严重的水稻病害之一。抗病基因能够识别病原无毒蛋白而导致抗病反应。抗病基因以单基因或基因簇的形式存在, 它是通过基因复制或基因多样性而产生的。近几年来,由于抗病基因的不断克隆和功能分析, 使人们更好地理解和认识抗病机制。本文总结了目前抗病基因的克隆和功能分析进展, 并对抗病基因的进化, 抗病蛋白和病原无毒因子之间的相互作用、相互影响和进化以及无毒因子的结构进行了剖析, 同时指出这些理论对植物保护的潜在含义。
Rice blast is caused by the fungus Magnaporthe oryzae and is one of the most serious rice diseases in the world. Disease-resistant genes can recognize pathogenic non-toxic protein and lead to disease-resistant response. Disease-resistant genes exist as single genes or as clusters of genes, which are produced by genetic duplication or genetic diversity. In recent years, due to the continuous cloning and functional analysis of disease-resistance genes, people are better able to understand and recognize the disease-resistant mechanisms. This article summarizes the current cloning and functional analysis of disease-resistant genes and analyzes the evolution of disease-resistant genes, the interaction, interaction and evolution of disease-resistant proteins and pathogenic non-toxic factors and the structure of non-toxic factors, Also point out the potential implications of these theories for plant protection.
