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 "d"ouble-stranded, "i"nsect, "nove"m (Latin for nine the number of genome segments), "rna" virus. There is one species in the genus: "Aedes pseudoscutellaris reovirus". 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. Genome. Genomes are linear and segmented. There are nine segments which code for nine proteins. 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. Taxonomy. There is one species in the genus:
