Mitoviruses are afamily ofpositive-strand RNA viruses that constitute the familyMitoviridae.Fungi serve as natural hosts. There are four genera in the family.[1][2]
Mitoviruses have no true virion. They do not have structural proteins or acapsid.[1]
Mitoviruses have nonsegmented, linear,positive-sense, single-strandedRNA genomes. The genome has oneopen reading frame which encodes theRNA-dependent RNA polymerase (RdRp). The genome is associated with the RdRp in thecytoplasm of the fungi host and forms a nakedribonucleoprotein complex.[1]
Viral replication is cytoplasmic. Replication follows the positive-strand RNA virus replication model. Positive-strand 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. Transmission routes are parental and sexual.[1]
The family contains four genera:[2]
