摘要：

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.
