Victorivirus is a genus of viruses, in the family Pseudototiviridae. Filamentous fungi serve as natural hosts. There are 32 species in this genus.[1][2]
Structure
Viruses 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]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Victorivirus | Icosahedral | T=2 | Non-enveloped | Linear |
Life cycle
Viral 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]
