| 摘 要： | 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理。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保的潜在含义。

| Abstract: | Rice blast disease caused by the fungal pathogen Magnaporthe oryzae is one of the most destructive rice diseases worldwide. Resistance (R) genes to blast encode proteins that detect pathogen signaling molecules encoded by M. oryzae viru- lence (AVR) genes. R genes can be a single copy gene or a member of clustered gene families that have evolved through duplica- tion and diversification. Recent advances in blast R gene cloning and subsequent characterization have provided useful insights into R gene mediated signaling transduction pathways. This review summarizes recent advances in cloning and characterization of blast R genes, and presents an update on evolutionary dynamics of R proteins, their interaction and co-evolution with the signaling molecules encoded by the AVR genes, and potential implications for crop protection. |
