Powdery mildew diseases are economically important diseases, caused by obligate biotrophic fungi of the Erysiphales. To understand the complex inheritance of resistance to the powdery mildew disease in the model plant Arabidopsis thaliana, quantitative trait loci analysis was performed using a set of recombinant inbred lines derived from a cross between the resistant accession Kashmir-1 and the susceptible accession Columbia glabrous1. We identified and mapped three independent powdery mildew quantitative disease resistance loci, which act additively to confer disease resistance. The locus with the strongest effect on resistance was mapped to a 500-kbp interval on chromosome III.
白粉病是具有经济重要性的病害,由白粉菌目专性活体营养型真菌引起。为了解模式植物拟南芥对白粉病抗性的复杂遗传机制,利用从抗性材料克什米尔-1与感病材料哥伦比亚光叶1杂交产生的一组重组自交系进行了数量性状基因座分析。我们鉴定并定位了3个独立的白粉病数量抗病基因座,它们以加性方式发挥作用赋予抗病性。对抗性影响最强的基因座被定位到第三条染色体上一个500千碱基对的区间内。
