Gokushovirinae
''Gokushovirinae'' is a subfamily of viruses in the family ''Microviridae''. There are 8 species in this subfamily, divided among 4 genera.
Species and genera
The following species and genera are assigned to the family:
* Genus: ''Bdellomicrov ...
''. Spiroplasma bacteria serve as natural hosts. There is only one species in this genus: ''Spiroplasma virus SpV4''.
Structure
Viruses in ''Spiromicrovirus'' are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 30 nm. Genomes are circular, around 6.1kb in length.
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by pilus-mediated adsorption into the host cell. Replication follows the ssDNA rolling circle model. DNA-templated transcription is the method of transcription. The virus exits the host cell by bacteria lysis.
Spiroplasma bacteria serve as the natural host.
