Alvernaviridae
Alvernaviridae is a family of viruses. Dinoflagellates serve as natural hosts. There is currently only one species in this family: the type species Heterocapsa circularisquama RNA virus 01. Diseases associated with this family include: control of the host population possibly through lysis of the host cell.[1][2]

Structure
Viruses in Alvernaviridae are non-enveloped, with icosahedral and spherical geometries, and T=3 symmetry. The diameter is around 34 nm. Genomes are linear and non-segmented, around 4.4kb in length.[1]
Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
---|---|---|---|---|---|
Dinornavirus | Icosahedral | T=3 | 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. Dinoflagellates serve as the natural host.[1]
