A new positive-sense, single-stranded RNA virus, tentatively named "Valeriana jatamansi tymovirus 1" (VaJV1, OQ730267), was isolated from Valeriana jatamansi Jones displaying symptoms of vein-clearing in Yunnan Province, China. The complete genome of VaJV1 consists of 6,215 nucleotides and contains three open reading frames (ORFs). The genome structure of VaJV1 is typical of members of the genus Tymovirus. BLASTn analysis and multiple sequence alignments showed that the complete genome and coat protein of VaJV1 shared the most sequence similarity (65.5% nucleotides and 50.5% amino acid sequence identity) with an isolate of the tymovirus okra mosaic virus (NC_009532). Phylogenetic analysis confirmed that VaJV1 clustered most closely with other tymoviruses. We propose that Valeriana jatamansi tymovirus 1 represents a new species within the genus Tymovirus.
一种新的正链、单链 RNA 病毒，暂命名为“缬草 tymovirus 1”（VaJV1，OQ730267），从表现出叶脉清除症状的缬草中分离出来。中国云南省。VaJV1 的完整基因组由 6215 个核苷酸组成，包含三个开放阅读框（ORF）。VaJV1 的基因组结构是 tymovirus 属成员的典型特征。BLASTn 分析和多序列比对表明，VaJV1 的完整基因组和外壳蛋白与 okra mosaic virus 的 tymovirus 分离株（NC_009532）具有最高的序列相似性（核苷酸 65.5%和氨基酸序列同一性 50.5%）。系统发育分析证实 VaJV1 与其他 tymoviruses 聚类最密切。我们建议，缬草 tymovirus 1 代表 tymovirus 属中的一个新种。
