摘　　要：抗病基因的研究是抗病育种及防治植物病害的基础。拟南芥NDR1(Non-race-specific disease resistance 1)基因,编码一个质膜定位蛋白,在R基因介导的抗性中具有重要作用。NDR1能与CC-NB-LRR(卷曲螺旋核酸结合或富亮氨酸重复)类抗病蛋白相互作用。以拟南芥抗病基因NDR1及其蛋白结构的研究进展为基础,综述了NDR1的广谱抗病性和抗病分子机理。The research of resistance genes is the basis of disease resistance breeding and plant diseases controlling. Arabidopsis NDR1 （non-race-specific disease resistance 1）gene, encoding a plasma membrane protein, plays an important role in the R gene mediated disease resistance, by interacting with CC-NB-LRR（nucleic acid binding or coiled-coil leucine-rich repeat）class of antiviral proteins. Here, we summarized the latest progresses of Arabidopsis NDR1 gene and the broad-spectrum disease resistance of NDR1.
