Dinovernavirus

Dinovernavirus is a genus of viruses, in the family Reoviridae, in the subfamily Spinareovirinae. These viruses replicate in a variety of mosquito cell lines. There is currently only one species in this genus: the type species Aedes pseudoscutellaris reovirus.[1][2]

Structure

Viruses in Dinovernavirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 49-50 nm. Genomes are linear and segmented. The genome codes for 9 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]

gollark: How would you know to look for it without someone telling you?
gollark: I mean, you'd have to google what they were if you knew not.
gollark: Costs XP, though.
gollark: Ah.
gollark: Using `uninstall`?
