Quadriviridae is a family of double-stranded RNA viruses with a single genus Quadrivirus.[1] Fungi serve as natural hosts. The name of the viruses derive from the quadripartite genome where in Latin quad means four. There is currently only one species in this family: the type species Rosellinia necatrix quadrivirus 1.[2][3]
Structure
Viruses in the family Quadriviridae have a non-enveloped isometric capsid. The diameter is around 48 nm.
Genome
Family member genomes are composed of double-stranded RNA. They are divided in to four segments which each code for a protein. The length of the different segments are between 3.5 to 5.0 kbp. The total genome is around 16.8 kbp.[2][3]
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Fungi serve as the natural host.[2][3]
Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
---|---|---|---|---|---|---|---|
Quadrivirus | Fungi | None | Unknown | Cytoplasmic exchange; hyphal anastomosis; sporogenesis | Unknown | Unknown | Cytoplasmic exchange; hyphal anastomosis; sporogenesis |
Taxonomy
The family Quadrivirdae has one genus Quadrivirus which contains the species:
- Rosellinia necatrix quadrivirus 1
