The complete genomic sequence of a plant rhabdovirus that was identified in Cnidium officinale in Yeongyang-dun, South Korea, is reported here. The virus, tentatively named "cnidium virus 1" (CnV1), has a negative-sense RNA genome of ~ 14 kb, and its organization most closely resembles that of unsegmented plant rhabdoviruses, containing six antisense open reading frames (ORFs) in the order 3'-N-P-P3-M-G-L-5'. Intergenic regions containing conserved sequences separate the genes. The genome of CnV1 is 37.8-56% identical in its complete nucleotide sequence to betanucleorhabdoviruses and other related rhabdoviruses. Therefore, based on the sequence similarity criteria for species demarcation, its genome organization, and its phylogenetic position, CnV1 should be classified as a new member of the genus Betanucleorhabdovirus in the family Rhabdoviridae. CnV1 is the first rhabdovirus found in C. officinale.
这里报道了一种在韩国荣阳郡的蛇床子中鉴定出的植物弹状病毒的完整基因组序列。该病毒暂定名为“蛇床子病毒 1”（CnV1），具有约 14 kb 的负义 RNA 基因组，其组织最类似于未分段的植物弹状病毒，包含六个反义开放阅读框（ORF），按 3'-N-P-P3-M-G-L-5'的顺序排列。包含保守序列的基因间区将基因隔开。CnV1 的全核苷酸序列与其 betanucleorhabdoviruses 和其他相关弹状病毒的同源性为 37.8-56%。因此，根据物种划分的序列相似性标准、其基因组组织和系统发育位置，CnV1 应被归类为 Rhabdoviridae 家族 Betanucleorhabdovirus 属的一个新成员。CnV1 是在蛇床子中发现的第一种弹状病毒。
