侵染甘薯的DNA病毒研究进展

Advances in research of DNA virus infecting sweet potato

甘薯是重要的粮食作物和食品加工及工业原料。我国是世界上最大的甘薯生产国。病毒病是甘薯上的重要病害,目前世界上已报道的侵染甘薯的DNA病毒主要归属于双生病毒科Geminiviridae和花椰菜花叶病毒科Caulimoviridae。近年来,双生病毒等DNA病毒严重影响我国甘薯的产量、品质以及食品加工产业。本文简介了甘薯在我国的重要地位和种植情况;具体介绍了侵染甘薯的菜豆金色花叶病毒属Begomovirus、玉米线条病毒属Mastrevirus及杆状DNA病毒属Badnavirus的病毒特征、分子变异、分类现状和检测方法。结合甘薯生产的实际情况,提出了目前甘薯DNA病毒研究中存在的问题及思考。本文旨在为我国甘薯DNA病毒病的综合防控提供理论依据。

Sweet potato is an important food crops and food processing and industrial raw materials.China is the largest producer of sweet potato in the world.Virus diseases were the important diseases on sweet potato.The reported viruses infecting sweet potato mainly belonged to Geminiviridae and Caulimoviridae.In recent years,begomoviruses and other DNA viruses became serious threats to planting industry of sweet potato in China and influenced the yield,quality of sweet potato and the food processing industry.In order to know more about the DNA viruses infecting sweet potato,the important status and planting situation of sweet potato in China were briefly introduced,and the characteristics,molecular variation,classification situation and detection methods of these viruses belonged to Begomovirus,Mastrevirus and Badnavirus were concretely described in this review.Combining with the actual situation of sweet potato planting in China,the existing problems and thinking in the research of DNA viruses infecting sweet potato were brought up.The objects of this paper were to provide the theoretical basis for the comprehensive prevention and control for sweet potato diseases infected by DNA viruses.
