蜂斗菜花叶病毒（Butterbur mosaic virus，ButMV）是从日本蜂斗菜（Japanese butterbur）中分离到的一种病毒，属于卡拉病毒属（Carlavirus）。在这里，我们报告的完整核苷酸序列和基因组组织的ButMV。ButMV的基因组由8，662个核苷酸组成，预计含有6个ORF。ButMV复制酶基因和CP基因与其它香芹病毒的核苷酸同源性分别为46.4- 54.9%和43.2-62.1%，氨基酸同源性分别为38.6- 46.6%和31.3-65.0%。系统进化分析表明，ButMV复制酶和CP分别与彩叶草脉坏死病毒和香石竹潜伏病毒的亲缘关系最近。总之，我们的结果表明，ButMV是卡拉病毒属的一个独特的物种。
Butterbur mosaic virus (ButMV), a member of the genus Carlavirus, was isolated from Japanese butterbur. Here we report the complete nucleotide sequence and genome organization of ButMV. The genome of ButMV consists of 8,662 nucleotides in length and is predicted to contain six ORFs. The ButMV replicase and CP genes share 46.4-54.9 and 43.2-62.1% nucleotide and 38.6-46.6 and 31.3-65.0% amino acid sequence identities, respectively, with those of other carlaviruses. Based on phylogenetic analysis, we suggested that ButMV replicase and CP is most closely related to coleus vein necrosis virus and carnation latent virus, respectively. Together, our results demonstrate that ButMV was a distinct species of the genus Carlavirus.
