In this brief note, we review the taxonomic history of dahlia mosaic virus (DMV) and related viruses. DMV is the only officially recognized caulimovirus known to infect dahlia (Dahlia variabilis) plants, although this virus appears to be relatively rare as a pathogen compared to a more recently described but unclassified caulimovirus called dahlia common mosaic virus (DCMV). We have undertaken a new set of analyses to test the hypothesis that DCMV represents a new caulimovirus species whose members infect dahlia, but we ultimately reject this hypothesis. A probable sequencing error was identified in the reference genome sequence of DMV, and consequently, we recommend that an alternative virus isolate be nominated as the exemplar for this species. In accordance with the new binomial nomenclatural system, it is proposed that the virus species be called "Caulimovirus dahliae".
在这篇简要说明中，我们回顾了百日草黄斑驳病毒（DMV）和相关病毒的分类历史。DMV 是唯一一种被官方认可的 caulimovirus，已知会感染大丽花（Dahlia variabilis）植物，尽管与一种最近描述但尚未分类的 caulimovirus（称为大丽花普通花叶病毒，DCMV）相比，DMV 作为病原体相对较少见。我们进行了一系列新的分析，以检验 DCMV 代表一种新的 caulimovirus 物种的假说，其成员感染大丽花，但我们最终拒绝了这一假说。在 DMV 的参考基因组序列中发现了一个可能的测序错误，因此，我们建议选择另一个病毒分离株作为该物种的代表。根据新的双名命名系统，建议将该病毒物种命名为“Caulimovirus dahliae”。
