Guttaviridae

Guttaviridae
Virus classification
(unranked): Virus
Family: Guttaviridae
Genera

Guttaviridae is a family of viruses. Archaea serve as natural hosts. There are two genera in this family, containing one species each. The name is derived from the Latin gutta, meaning 'droplet'.

Taxonomy

The family currently contains one genera and species:

Genus Alphaguttavirus and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.

Structure

Viruses in the family Guttaviridae are enveloped. The diameter is around 70–95 nm, with a length of 110–185 nm. Genomes are circular, around 20kb in length. The virons consist of a coat, a core, a nucleocapsid, and projecting fibers at the pointed end. The surface of the virion has a beehive-like ribbed surface pattern with protrusions that are densely covered by a 'beard' of long fibers at its pointed end. The genome is extremely heavily methylated.[citation needed]

Life cycle

DNA-templated transcription is the method of transcription. Archaea serve as the natural host.
