}}Victorivirus is a genus of viruses, in the family Totiviridae. Filamentous fungi serve as natural hosts. There are currently 14 species in this genus including the type species Helminthosporium victoriae virus 190S.[1][2] TaxonomyGroup: dsRNA{{Collapsible list|title= Order: Unassigned|1={{Collapsible list| framestyle=border:none; padding:1.0em;|title=Family: Totiviridae |1={{hidden begin|title=Genus: Victorivirus}}
}} }}[2] StructureViruses in Victorivirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 40 nm. Genomes are linear, around 4.6-6.7kb in length. The genome has 2 open reading frames.[1]
Life cycleViral replication is cytoplasmic. Entry into the host cell is achieved by virus remains intracellular. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Translation takes place by RNA termination-reinitiation. The virus exits the host cell by cell to cell movement. Filamentous fungi serve as the natural host.[1]
