| 中文摘要: |
| 由病害造成的粮食作物产量损失严重制约了全球粮食安全，培育抗病品种是公认的应对病害最经济、有效的方法，挖掘抗病基因、阐明广谱抗病机理是水稻广谱抗病资源高效利用以及寻找病害防控新途径基础。近20年来，植物免疫机理取得了系列重大进展，主要粮食作物广谱抗病研究也取得了显著成效，部分抗性基因的分子作用机制已被揭示。回顾和综述了水稻广谱抗病研究的主要进展（包括已克隆的主要广谱抗病基因，广谱抗性分子机制），分析了该领域研究面临的问题、机遇与挑战，并对广谱抗病研究的发展及其在水稻生产上应用进行展望。 |
| 英文摘要: |
| Yield loss caused by crop diseases seriously restricts global food security. Breeding disease-resistant varieties with resistant（R） gene is acknowledged as the most economical and effective way to control diseases. Therefore, exploring broad-spectrum resistant（BSR） genes to pathogens and clarifying the underlying mechanism are the basis for effective utilization of BSR resources and finding the new approaches for disease control. In the past 20 years, significant progress has also been made in plant immune mechanism and remarkable achievements have been made in researches on broad-spectrum disease resistance of major grain crops, and the potential molecular mechanisms of some BSR have been revealed. Here, the advances of broad-spectrum disease resistance in rice（including the representative cloned BSR genes and their molecular mechanisms） were reviewed. In addition, the problems, opportunities and challenges encountered by BSR were analyzed, and the development of BSR research and its application in rice production were prospected. |
