甘薯是广西第三大粮食作物,病毒病是广西甘薯的主要病害之一。为明确为害广西甘薯的病毒种类,利用RT-PCR或PCR技术检测采自广西南宁、北海、玉林、宜州、崇左和桂林等市的甘薯样品127个,并对扩增产物进行测序和所获序列的Blast分析。结果表明:在广西采集到的127个甘薯样品中,共检测出11种病毒,包括10种RNA病毒:甘薯羽状斑驳病毒(Sweet potato feathery mottle virus,SPFMV)、甘薯G病毒(Sweet potato virus G,SPVG)、甘薯褪绿矮化病毒(Sweet potato chlorotic stunt virus,SPCSV)、甘薯轻型斑点病毒(Sweet potato mild speckling virus,SPMSV)、甘薯C病毒(Sweet potato virusC,SPVC)、黄瓜花叶病毒(Cucumber mosaic virus,CMV)、甘薯褪绿斑病毒(Sweet potato chlorotic fleck virus,SPCFV)、甘薯脉花叶病毒(Sweet potato vein mosaic virus,SPVMV)、甘薯潜隐病毒(Sweet potato latent virus,SPLV)、甘薯轻型斑驳病毒(Sweet potato mild mottle virus,SPMMV)和1种DNA病毒,即甘薯卷叶病毒(Sweet potato leaf curl virus, SPLCV)。
