The '''''Narnaviridae''''' are a family of positive single stranded RNA viruses. They are capsid-less RNA virus <ref name="Capsid-Less RNA Viruses">[http://onlinelibrary.wiley.com/doi/10.1002/9780470015902.a0023269/abstract Capsid-Less RNA Viruses]</ref> |

The genome is unipartate and between 2.3 and 3.5 kilobases in length. It encodes a single gene - the RNA dependent RNA polymerase. This protein is associated with the genome in the cytoplasm of the host.<ref name=Solorzano2000>Solorzano A, Rodríguez-Cousiño N, Esteban R, Fujimura T (2000) Persistent yeast single-stranded RNA viruses exist in vivo as genomic RNA.RNA polymerase complexes in 1:1 stoichiometry. J Biol Chem 275(34):26428-26435</ref> |

They infect [[fungus|fungi]] and [[oomycete]]s.<ref name=Cai2011>Cai G, Myers K, Fry WE, Hillman BI (2011) A member of the virus family Narnaviridae from the plant pathogenic oomycete ''Phytophthora infestans''. Arch Virol </ref> These viruses are commonly found infecting yeast. |
|||
==Taxonomy== |
|||
Two genera have been recognised to date. The Mitoviruses infect the mitochondria of fungi while the Narnaviruses remain within the cytoplasm of the host. |
|||
*Genus ''[[Narnavirus]]''; type species: ''[[Saccharomyces cerevisiae 20SRNA narnavirus]]'' |
|||
*Genus ''[[Mitovirus]]''; type species: ''[[Cryphonectria parasitica mitovirus-1 NB631]]'' |
|||
(Note that although the ''Narnaviridae'' are now treated with other (+)ssRNA viruses, they were previously given their own group). |
