The complete genomic RNA sequence of a tentative new umbravirus from Patrinia scabiosaefolia, tentatively named "patrinia mild mottle virus" (PatMMoV), was determined. The genome of PatMMoV consists of 4,214 nucleotides and has a typical umbravirus genome organization with four open reading frames. BLAST searches showed that the complete nucleotide sequence of PatMMoV had the highest identity (72%; 50% query coverage) to Ixeridium yellow mottle-associated virus 2 (IxYMaV-2; an unclassified umbravirus). In addition, phylogenetic analysis and pairwise comparisons showed that PatMMoV and IxYMaV-2 were the most closely related and placed in the same clade within a group of umbraviruses. These results suggest that PatMMoV is a putative new member of the genus Umbravirus in the family Tombusviridae.
从苦荬菜中分离到一株暂定的新 Umbravirus，暂命名为“苦荬菜轻斑驳病毒”（PatMMoV），并测定了其完整基因组 RNA 序列。PatMMoV 基因组由 4214 个核苷酸组成，具有典型的 Umbravirus 基因组结构，包含四个开放阅读框。BLAST 搜索表明，PatMMoV 完整核苷酸序列与 Ixeridium yellow mottle-associated virus 2（IxYMaV-2；未分类的 Umbravirus）的同源性最高（72%；50%查询覆盖率）。此外，系统进化分析和两两比对显示，PatMMoV 和 IxYMaV-2 亲缘关系最近，在 Umbravirus 科的一个病毒组中位于同一分支。这些结果表明，PatMMoV 是 Tombusviridae 科 Umbravirus 属的一个假定新成员。
