Taxonomy
The following four species are assigned to the genus:[2]
- Punavirus P1
- Punavirus pv43
- Punavirus RCS47
- Punavirus SJ46
Structure
Viruses in Punavirus are non-enveloped, with icosahedral and head-tail geometries. The diameter is around 85 nm. Genomes are circular, around 100kb in length. The genome codes for 100 proteins.[1]

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
