作物广谱抗病研究现状与关键科学问题

Broad Spectrum Resistance in Main Crops:Recent Advances and Future Directions

培育抗病品种是应对作物病害威胁最经济有效的方法,广谱抗病资源发掘、抗病基因鉴定和抗病理论解析等是培育作物广谱抗病品种的基础。二十多年来,植物免疫反应及抗病研究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,包括克隆了系列广谱抗病基因并揭示了部分基因的抗病机理。本文对作物广谱抗病领域的主要研究进展进行了回顾与综述,提出了该领域亟需解决的关键科学问题,对作物广谱抗病研究面临的机遇与挑战进行了分析,同时对作物广谱抗病研究的发展进行了展望。

Breeding crop varieties with broad spectrum resistance(BSR)to pathogens is commonly known as the most economical and effective approach to control crop diseases.Thus,it is required to explore resistance resources,to identify BSRgenes,and to elucidate their underlying resistance mechanisms.Over the past two decades,many progresses have been obtained on BSRstudies,including several important BSRgenes having been cloned,and their molecular mechanisms having been revealed.In this review,we summarized the advances of crop BSR studies,raised some key scientific issues to be resolved,and put forward the current opportunities and challenges in this field.In addition,we also made some perspectives on study of crop BSR for the future.
