Mycoreovirus
# Mycoreovirus

Mycoreovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Fungi serve as natural hosts. Diseases associated with this genus include: hypovirulence of the fungal host. The name of the group derives from Ancient Greek myco which means fungus. There are three species in this genus.

## Structure

Viruses in genus Mycoreovirus are non-enveloped with icosahedral geometries. The outer capsid has T=13 symmetry and the inner capsid has T=2 symmetry. The diameter is around 80 nm. Genomes are linear and segmented, and around 23 kbp in total length. The genome codes for 12 proteins.

## 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.
