Guttaviridaeis a family ofviruses.Archaeaserve as natural hosts. There are two genera in this family, containing one species each.[1][2]The name is derived from theLatingutta,meaning 'droplet'.[3][4][5]
Taxonomy
[edit]The family currently contains one genera and species:[2]
- Betaguttavirus
- Aeropyrum pernix ovoid virus 1
GenusAlphaguttavirusand speciesSulfolobus newzealandicus droplet-shaped viruswere removed in ICTV version 2021.[6]
Structure
[edit]Viruses in the familyGuttaviridaeare enveloped. The diameter is around 70–95 nm, with a length of 110–185 nm. Genomes are circular, around 20kb in length.[2][3]The virons consist of a coat, a core, a nucleocapsid, and projecting fibers at the pointed end. The surface of thevirionhas 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
[edit]DNA-templated transcription is the method of transcription. Archaea serve as the natural host.[2][3]
