double-stranded RNA viruses
Double-stranded RNA viruses (dsRNA viruses) are a polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid. The double-stranded genome is used to transcribe a positive-strand RNA by the viral RNA-dependent RNA pol ...

Structure
Viruses in the genus ''Alphachrysovirus'' are non-enveloped, with icosahedral geometries, and T=1, T=2 symmetry. The diameter is around 35–40 nm.Genome
Genomes are linear double-stranded RNA which is around 12.5 kbp in length. The genome codes for four proteins. The genome has three double stranded RNA segments. All have extended highly conserved terminal sequences at both ends.
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. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host.Taxonomy
