''Tombusviridae'' is a family of single-stranded positive sense RNA plant viruses. There are currently 71 species in this family, divided among 13 genera.〔(【引用サイトリンク】url=http://viralzone.expasy.org/all_by_species/53.html )〕〔(【引用サイトリンク】title=Virus Taxonomy: 2014 Release )〕 The name is derived from the type species of the ''Tombusvirus'' genus, Tomato bushy stunt virus (TBSV).〔Habili, N. and Symons, R. H. (1989). (Evolutionary relationship between luteoviruses and other RNA plant viruses based on sequence motifs in their putative RNA polymerases and nucleic acid helicases. ) ''Nucleic Acids Research'' 17:23, 9543–55〕 ==Genome== All Tombusviridae have a non-segmented linear genome, with the exception of Dianthoviruses, whose genome is bipartite.〔(Wiley InterScience Encyclopedia of Life Sciences: Tombusviridae )〕 The genome is approximately 4.6-4.8kb in length, with a 5' cap, and it encodes 4-6 ORFs. The polymerase encodes an amber stop codon which is the site of a readthrough event within ORF1, producing two products necessary for replication. There is no helicase encoded by the virus.
