Barnaviridae is a family of viruses. Cultivated mushroom serve as natural hosts. There are currently only one genus (Barnavirus) and one species in this family: the type species Mushroom bacilliform virus. Diseases associated with this family include: La France disease.[1][2]

Structure
Viruses in Barnaviridae are non-enveloped, with icosahedral and Bacilliform geometries, and T=1 symmetry. These viruses are about 50 nm long. Genomes are linear, around 4kb in length. The genome has 43 open reading frames.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Barnavirus | Icosahedral | T=1 | Non-Enveloped | Linear | Monopartite |
Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription is the method of transcription. Cultivated mushroom serve as the natural host.[1]
| Genus | Host Details | Tissue Tropism | Entry Details | Release Details | Replication Site | Assembly Site | Transmission |
|---|---|---|---|---|---|---|---|
| Barnavirus | Cultivated mushroom: agaricus bisporus | None | Horizontal; vertical | Horizontal: via mycelium; horizontal: basidiospores | Cytoplasm | Cytoplasm | Horizontal: via mycelium; horizontal: basidiospores |
