Quadriviridae is a family of viruses with a single genus Quadrivirus.[1] Fungi serve as natural hosts. There is currently only one species in this family: the type species Rosellinia necatrix quadrivirus 1.[2][3]
Structure
Viruses in Quadriviridae are non-enveloped. The diameter is around 48 nm.
Genome
Genomes are linear and segmented, around 16.8kb in length. The genome codes for four proteins.[2][3]
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Fungi serve as the natural host.[2][3]
