Notes on Genus: Dinovernavirus
Type member: Aedes pseudoscutellaris reovirus
This is one of the animal virus genera in the family Reoviridae
. Members have 9 segments (fewer than any other genus in the family) and infect insects. The name reflects the fact that these are d
nsect viruses with nine (latin novem
Virions isometric (icosahedral), 55-69 nm in diameter, with a single capsid shell and hollow surface spikes similar to those of the genus Cypovirus
Linear, double stranded RNA in 9 segments. Five of these are larger than 3 kb in size. Each virion contains a single copy of the entire genome. Total genome c.
23000 nucleotides long.
Genus Genomic Organization
Each segment has a single ORF.
