Prasinovirus is a genus of large double-stranded DNA viruses, in the family Phycodnaviridae that infect phytoplankton in the Prasinophyceae. The genus contains two species,[1][2] including Micromonas pusilla virus SP1, which infects the cosmopolitan photosynthetic flagellate Micromonas pusilla.[3]
There is a large group of genetically diverse but related viruses that show considerable evidence of lateral gene transfer.[4][5]
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2]
- Prasinovirus micromonas, Micromonas pusilla virus SP1
- Prasinovirus ostreotauri, Ostreococcus tauri virus OtV5
Structure
Viruses in Prasinovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 104-118 nm.[1]
