植物非寄主抗性机制研究进展

非寄主抗性是植物对多数病原菌的抗病形式,具有广谱性和持久性。早前多认为非寄主抗性是植物体识别病原菌激发子,释放抗病信号,经一系列级联放大反应,进而产生非寄主抗性,目前研究还发现了一些参与病原菌防御的非寄主抗性基因和转录因子。从非寄主抗性的组分和类型对植物非寄主抗性机制进行阐述。...

Bibliography:	44-1267/S Non-host disease resistance is the most common form of disease resistance exhibited by plants against the majority of potentially pathogenic microorganisms. People think non-host plant recognized the pathogenic excitor and released resistance signal, nonhost resistance was triggered through resistance signal cascade amplification reaction, recent research find that some non-host resistance genes and few transcription factor participate non-host resistance response. This article summarized the mechanism of non-host resistance by expounding it＇s components and categories.
