| 摘 要： | 综合近年国内外对植物抗病基因的研究和我们对水稻抗病基因的研究成果，对植物抗病基因进行归纳分类，并就其结构、功能、作用机理和信号传导进行分析和讨论。根据植物抗病基因编码蛋白的保守结构，将植物抗病基因分成NBS-LRR、eLRR-TM、eLRR-TM-pkinase、STK和其他五大类。不同类型的基因在细胞水平上的分布不一样，NBS、激酶和LRR在不同类型的基因之间结构差异也较大，但是它们通过各不相同的作用机理参与细胞对病原体的防御。

| Abstract: | The current progress of research into plant disease-resistance genes (R-genes) was reviewed. We discussed their resistance mechanisms and signaling. According to a conservative structure, plant R-genes could be classified into five groups: NBS-LRR, eLRR-TM, eLRR-TM-pkinase,
STK and others. R-genes with NBS, pkinase or eLRR play an important role in plant disease resistance by their respective pathways, although their structures were different. |
