Structure
Viruses in Gammaflexiviridae are non-enveloped, with flexuous and Filamentous geometries. The diameter is around 12-13 nm, with a length of 720 nm. Genomes are linear, around 6.8kb in length. The genome has 2 open reading frames.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Mycoflexivirus | Filamentous | 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. Fungi serve as the natural host.[1]
| Genus | Host Details | Tissue Tropism | Entry Details | Release Details | Replication Site | Assembly Site | Transmission |

| Mycoflexivirus | Plants | None | Viral movement; mechanical inoculation | Viral movement | Cytoplasm | Cytoplasm | Mechanical inoculation: pseudococcid mealybugs; Mechanical inoculation: aphids |
