摘要
The complete genome of a novel virus provisionally named tobacco virus 1(TV1) was determined and identified from leaves of tobacco(Nicotiana tabacum) exhibiting leaf mosaic and yellowing symptoms in Anhui Province, China. The genome sequence of TV1 consists of 15,395 nucleotides with 61.6% nucleotide sequence identity with Mint virus 1(MV1). Its genome organization is similar to MV1 containing nine open reading frames(ORFs) which potentially encode proteins with putative functions in virion assembly, cell‐to‐cell movement and suppression of RNA silencing. Phylogenetic analysis of the heat shock protein 70 homolog(HSP70h) placed TV1 alongside members of the genus Closterovirus in the family Closteroviridae. To ourknowledge, this study is the first report of complete genome sequence of a closterovirus identified in tobacco.
