摘　　要：甘薯曲叶病是限制世界甘薯生产的主要病毒病害之一,已在美国、西班牙、巴西、中国、日本、韩国和南非等国甘薯产区广泛发生。甘薯曲叶病毒(sweet potato leaf curl virus,SPLCV)是引起该病害的主要病原之一,属双生病毒科(Geminiviridae)菜豆金色花叶病毒属(Begomovirus)的单组分病毒,其基因组仅含有DNA-A组分,由昆虫介体烟粉虱持久性传播,也可通过嫁接传播。在中国,自2006年首次在辽宁大连的甘薯上分离鉴定到SPLCV以来,目前已在福建、浙江、江苏和云南等多个地区发现SPLCV引起的病害,受侵染寄主植物包括甘薯、裂叶牵牛和圆叶牵牛。基于国内外的文献报道,对SPLCV的发生、分布、分子特征和流行病学等方面进行了较全面的综述,同时指出存在问题并加以讨论。鉴于SPLCV对全球甘薯生产的威胁日益加剧,本研究可为监控甘薯曲叶病害提供理论依据。Sweet potato leaf curl disease is the most devastating virus diseases to sweet potato production around the world.The disease has been spreading widely in sweet potato growing areas in the United States,Spain,Brazil,China,Japan,Korea and South Africa.Sweet potato leaf curl virus（SPLCV） is one of the main pathogens which belongs to the monopartite begomovirus（genus Begomovirus,family Geminivirade）,which only possessing the DNA-A genomic component.SPLCV is transmitted by Bemisia tabaci in a persistent manner and grafting.In China,SPLCV was firstly isolated from the sweet potato in Dalian City of Liaoning Province in 2006,after then,SPLCV was isolated from sweet potato,Ipomoea purpurea and Ipomoea indica in Fujian,Zhejiang,Jiangsu and Yunnan Provinces.Based on the literatures at home and abroad,the occurrence,distribution,molecular characteristics,epidemiology of SPLCV were summarized,meanwhile,the problems were also pointed out and discussed.The threat of SPLCV on sweet potato production was aggravating around the world.The study will provide the basis for the prevention and control of SPLCV.
