Bacillarnavirus is a genus of viruses in the family Marnaviridae. Marine diatoms serve as natural hosts. There are three species in this genus.[1][2]
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[1][3]
- Bacillarnavirus nagasakii, Rhizosolenia setigera RNA virus 01
- Bacillarnavirus setoensis, Chaetoceros tenuissimus RNA virus 01
- Bacillarnavirus yujii, Chaetoceros socialis forma radians RNA virus 1
Structure
Viruses in Bacillarnavirus are non-enveloped, with icosahedral, spherical, and round geometries, and T=pseudo3 symmetry. The diameter is around 30-32 nm. Genomes are linear and non-segmented, around 8.8-9.5kb in length. The genome has 2 open reading frames.[2]
