摘要: 综述了近年来国内外马铃薯帚顶病毒(PMTV)所取得的研究进展;简述了PMTV的分布与传播、分子特征、病理特征、致病机理及其检测方法,认为PMTV主要出现在气温冷凉的高纬度、高海拔地区的马铃薯上,能通过种薯和粉痂菌传播,诱导马铃薯块茎发生环状坏死;分析了该病毒的特殊性及防治的难点;认为今后要深入研究粉痂菌、马铃薯、PMTV三者之间的相互作用,挖掘PMTV抗性基因,开展马铃薯抗PMTV育种,建立快速准确的PMTV检测方法,探讨同时防治粉痂病和PMTV的途径。

Abstract: The progresses of research on potato mop top virus (PMTV) were reviewed in this paper. The distribution and transmission, molecular characteristic, symptoms, pathogenic mechanism of PMTV and its detection methods were briefly introduced. The virus occurred in potatoes grown in high-latitude or high-altitude regions with cooler climates and was transmitted by seeds and Spongospora subterranea, the causal agent of potato powdery scab disease .and could cause potato spraing, a serious tuber disease whose symptoms include necrotic arcs and lines in infected tubers. The particularity of PMTV and the difficulty to prevention of this virus were analyzed. The further researches should be focus on the interaction of powdery scab fungus, potato plants and PMTV, and on mining the resistance genes and carrying out potato breeding for the resistance to PMTV, and on the establishment of a rapid and accurate PMTV detection method, and on strategy for control and management of both powdery scab and PMTV.
