Mycoreovirus is a genus of viruses, in the family Reoviridae, in the subfamily Spinareovirinae. Fungi serve as natural hosts. There are currently three species in this genus including the type species Mycoreovirus 1. Diseases associated with this genus include: hypovirulence of the fungal host.[1][2]
Taxonomy

- Family: Reoviridae
- Sub-Family: Spinareovirinae
- Genus: Mycoreovirus
Structure
Viruses in Mycoreovirus are non-enveloped, with icosahedral geometries, and T=13 and T=2 symmetry. The diameter is around 80 nm. Genomes are linear and segmented, around 23kb in length. The genome codes for 12 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |

| Mycoreovirus | Icosahedral | T=13, T=2 | Non-enveloped | Linear | Segmented |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement, and monopartite non-tubule guided viral movement. Fungi serve as the natural host.[1]
