马铃薯Y病毒属（Potyvirus）是种类最多的一类植物病毒，现在国际病毒分类委员会（ICTV）承认的成员有168种。它们的病毒粒子都是弯曲线状的，长度在680-900nm，在植物细胞内可以形成圆柱形（风轮状）内含体或卷旋状内含体。基因组为正义单链RNA，翻译时先翻译成多聚蛋白（poly
Potyvirus is the most common type of plant virus, and now 168 are recognized by the International Virus Classification Commission (ICTV). Their virus particles are curved linear, the length of 680-900nm, in plant cells can form cylindrical (wind-like) inclusions or convoluted inclusions. The genome is a single-stranded sense RNA that translates into polyprotein (poly
