Narnavirus is a genus of viruses, in the family Narnaviridae. Fungi serve as natural hosts. There are currently only two species in this genus including the type species Saccharomyces 20S RNA narnavirus.[1][2] Narnaviruses have been shown to be required for sexual reproduction of Rhizopus microsporus.[3] Members of family Narnaviridae have no capsid.[4]
Structure
Genomes are linear and non-segmented.[2]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Narnavirus | 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. Transmission routes are parental and sexual.[2]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Narnavirus | Fungi | None | Horizontal; vertical | None | Cytoplasm | Cytoplasm | Horizontal: mating; vertical: parental |
