Genus: | Dinovernavirus |
Dinovernavirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Member viruses replicate in a variety of mosquito cell lines. The name is an abbreviation for double-stranded, insect, novem (Latin for nine the number of genome segments), rna virus. There is one species in the genus: Aedes pseudoscutellaris reovirus.[1][2]
Structure
Viruses in Dinovernavirus are non-enveloped. Their capsid is turreted and single shelled with icosahedral geometries and T=2 symmetry. The diameter is around 49–50 nm.[1]
Genome
Genomes are linear and segmented. There are nine segments which code for nine proteins.[1]
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by monopartite non-tubule guided viral movement. Mosquito serve as the natural host.[1]
Taxonomy
There is one species in the genus:[2]
- Aedes pseudoscutellaris reovirus
