Betaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. The family has 15 genera assigned to two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms.[1][2]
The following subfamilies and genera are recognized (-virinae denotes subfamily and -virus denotes genus):[2]
Structure
Viruses in Betaflexiviridae are non-enveloped, with flexuous and Filamentous geometries. The diameter is approximately 12–13 nm. Genomes are linear, around 6.5–9kb in length. The genome codes for 2 to 6 proteins.[1]
