摘要/Abstract

摘要： 甘薯病毒病害(Sweetpotato virus diseases，SPVD)是由甘薯羽状斑驳病毒(Sweetpotato feathery mottle virus，SPFMV)和甘薯褪绿矮化病毒(Sweetpotato chlorotic stunt virus，SPCSV)双重感染和协同互作引起的甘薯毁灭性病毒病。该病害自2012年在中国发现以来扩展迅速，2015年给广东省湛江市甘薯生产造成了巨大的经济损失。为了加强甘薯病毒病的防控，降低其带来的损失，文章归纳了SPVD分布范围及危害，分别总结了SPFMV和SPCSV的基因结构与功能、传播方式、主要的检测手段，认为发病严重地区可以从探明病毒株系种类切入、从SPCSV与SPFMV协生作用的分子机理深入，实现及时检测、及早预防和甘薯无毒化栽培。

Abstract: Sweetpotato virus disease (SPVD), which is caused by the dual infection and synergistic interaction of Sweetpotato feathery mottle virus (SPFMV) and Sweetpotato chlorotic stunt virus (SPCSV), is a devastating viral disease of sweetpotato. Since reported in China in 2012, it has been expended rapidly, and in 2015 it caused huge economic losses to sweetpotato production in Zhanjiang of Guangdong. In order to strengthen the prevention and control of sweetpotato virus disease and reduce losses, the distribution and harm of SPVD are summarized, and the gene structure and function, transmission and detecting means of SPFMV and SPCSV are reviewed respectively. It is suggested that in serious disease areas, detection of virus strains should be a key point, and molecular mechanism study about synergism between SPFMV and SPCSV should be further explored, thus to achieve the timely detection, early prevention and non-toxic cultivation of sweetpotato.
