甘薯羽状斑驳病毒(Sweet potato feathery mottle virus,SPFMV)可经蚜虫、摩擦、嫁接方式传播,是Y病毒组的一个成员。受此病毒感染的甘薯叶片上形成羽状褪绿斑,脉间褪绿斑点以及紫色环斑,有的品种出现紫色条纹。在甘薯块根上,有的呈严重纵向褐色龟裂,有的呈横向螺纹状木质化,有的块根内部形成木栓化,是危害甘薯最严重的病毒病害,可使甘薯严重退化及减产。无论是甘薯的抗病毒育种、病毒病害的防治,还是脱毒、无病毒甘薯种薯生产都离不开病毒的检测。灵敏的免疫吸附电镜(ISEM)检测方法被应用于各种病毒的检测中。然而由于旋花科植物组织成分
Sweet potato feathery mottle virus (SPFMV) can be spread by aphids, friction and grafting methods and is a member of the Y virus group. Affected by this virus, sweetpotato chlorotic spots, chlorotic spots and purple ring spots formed on the leaves of sweet potato, and some species appeared purple streaks. In the sweet potato root, some were serious longitudinal brown cracks, and some were horizontal thread-like lignification, and some inside the formation of woody bolt roots, is the worst endangering sweet potato disease virus, sweet potato can be a serious degradation and yield. Whether it is antivirus breeding sweet potato, virus disease prevention or virus-free, virus-free sweet potato seed production are inseparable from the detection of the virus. Sensitive immunoassay electron microscopy (ISEM) detection methods are used in the detection of various viruses. However, due to the composition of Convolvulaceae tissue
