The family Rhabdoviridae includes viruses with a negative-sense RNA genome. This family is divided into four subfamilies, and until recently, the subfamily Betarhabdovirinae, encompassing all plant-associated rhabdoviruses, was further divided into six genera. Here, we report the creation of two new genera within the subfamily Betarhabdovirinae - Alphagymnorhavirus and Betagymnorhavirus - to include recently described gymnosperm-associated viruses. The genus Alphagymnorhavirus includes nine species, while the genus Betagymnorhavirus includes only one species. Phylogenetic analysis indicated that these viruses form two well-supported clades that are clustered with the varicosaviruses, which have bisegmented genomes. In contrast, the 10 viruses included in the newly created genera have the distinctive feature that they have an unsegmented genome encoding five or six proteins. The creation of the genera Alphagymnorhavirus and Betagymnorhavirus has been ratified by the International Committee on Taxonomy of Viruses (ICTV).
Rhabdoviridae 科家族包括具有负义 RNA 基因组的病毒。该科分为四个亚科，直到最近，贝塔 Rhabdovirinae 亚科，包含所有与植物相关的 Rhabdoviruses，进一步分为六个属。在这里，我们报告在贝塔 Rhabdovirinae 亚科内创建了两个新属 - Alphagymnorhavirus 和 Betagymnorhavirus - 以包含最近描述的与裸子植物相关的病毒。Alphagymnorhavirus 属包括九个种，而 Betagymnorhavirus 属仅包括一个种。系统发育分析表明，这些病毒形成两个支持良好的分支，与具有双节段基因组的 Varicosaviruses 聚类。相比之下，新创建的属中包含的 10 种病毒具有独特的特征，即它们具有不节段的基因组，编码五个或六个蛋白质。Alphagymnorhavirus 和 Betagymnorhavirus 这两个属的创建已得到病毒分类国际委员会（ICTV）的批准。
