Notes on Genus: Dinovernavirus


Type member: Aedes pseudoscutellaris reovirus


General Description

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 double-stranded, insect viruses with nine (latin novem), RNA segments.


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.

Type Member Genomic Organization

  • Segment 1 (3817 nt) encodes the VP1 protein (134.7 kDa)
