Mitovirus
Mitovirus is a genus of viruses, in the family Mitoviridae. Fungi serve as natural hosts. There are currently five species in this genus including the type species Cryphonectria mitovirus 1.[1][2]

Structure
Genomes are linear and non-segmented.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Mitovirus | No structural proteins | Non-enveloped | Linear | Monopartite |
Life cycle
Viral replication is cytoplasmic. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host.[1]
