Air potato (Dioscorea bulbifera) plants being grown at the Florida Department of Agriculture and Consumer Services Division of Plant Industry Biological Control Laboratory II in Alachua County, Florida were observed exhibiting foliar mosaic symptoms characteristic of virus infection. A double-stranded RNA library generated from a symptomatic plant underwent high-throughput sequencing to determine if viral pathogens were present. Sequence data revealed the presence of two viral genomes, one with properties congruent with members of the genus Potyvirus (family Potyviridae), and the other with members of the genus Ampelovirus (family Closteroviridae). Sequence comparisons and phylogenetic placement indicate that both viruses represent novel species. The names "dioscorea mosaic virus" and "air potato virus 1" are proposed for the potyvirus and ampelovirus, respectively.
在佛罗里达州阿拉楚阿县的佛罗里达州农业和消费者服务部植物产业司生物防治实验室II种植的黄独（Dioscorea bulbifera）植株，被观察到呈现出病毒感染特有的叶片花叶症状。从一株有症状的植株构建的双链RNA文库进行了高通量测序，以确定是否存在病毒病原体。序列数据显示存在两个病毒基因组，一个的特性与马铃薯Y病毒属（马铃薯Y病毒科）成员一致，另一个与葡萄病毒属（长线形病毒科）成员一致。序列比较和系统发育定位表明这两种病毒均代表新物种。分别为马铃薯Y病毒和葡萄病毒提出了“薯蓣花叶病毒”和“黄独病毒1”的名称。
