Alphatetraviridae

provided by wikipedia EN

Alphatetraviridae is a family of viruses. Moths and butterflies serve as natural hosts. There are currently ten species in this family, divided among 2 genera. Infection outcome varies from unapparent to lethal.[1][2]

Taxonomy

Group: ssRNA(+)

[2]

Structure

Viruses in Alphatetraviridae are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and non-segmented, bipartite, around 6.5kb in length.[1]

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. Translation takes place by leaky scanning, and ribosomal skipping. Moths and butterflies serve as the natural host. Transmission routes are oral.[1]
