由致病疫霉Phytophthora infestans (Mont) de Bary引起的晚疫病是马铃薯生产上可导致绝收的世界性病害,在我国各地均有发生和流行[1]。传统的致病型鉴别只局限于表型上的分析,无法对复杂多变的晚疫病菌致病型变化进行快速准确的预测,因此有必要探索新的方法来弥补常规手段的不足,以便更加准确有效地监测其变化趋势。晚疫病菌与寄主马铃薯这一病理体系中的单一抗性基因和相应的无毒基因符合典型“基因对基因”学说,
The late blight caused by Phytophthora infestans (Mont) de Bary is a worldwide disease that can lead to the development of absolute yield in potato production, and has occurred and prevailed throughout China [1]. Traditional pathogenicity identification is restricted to phenotypic analysis and does not allow rapid and accurate predictions of the pathogenic changes of the complex and variable Phytophthora infestans. Therefore, there is a need to explore new ways of making up for the deficiencies of conventional approaches so that more Accurately and effectively monitor its changing trend. Phytophthora infestans and host potato in the pathological system of a single resistance gene and the corresponding non-toxic genes in line with the typical “gene to gene ” theory,
