Genus: | Spiromicrovirus |
Spiromicrovirus is a genus of viruses, in the family Microviridae, in the subfamily Gokushovirinae. Spiroplasma bacteria serve as natural hosts. There is only one species in this genus: Spiroplasma virus SpV4.[1][2]
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.[1]
Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
---|---|---|---|---|---|
Spiromicrovirus | Icosahedral | T=1 | Non-enveloped | Circular | Monopartite |
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.[1]
