Taxonomy

The family currently contains one genera and species:^[6][7]

• Betaguttavirus
  • Aeropyrum pernix ovoid virus 1 (Betaguttavirus kodakarajimaense)

Genus Alphaguttavirus and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.^[8]

Structure

Viruses in the family Guttaviridae are enveloped. The diameter is around 55–80 nm, with a length of 75–130 nm. Genomes are circular double-stranded DNA around 14 kilobases in length.^[2][3] Virions are ovoid or droplet-shaped and covered with globular subunits.^[2]

Life cycle

DNA-templated transcription is the method of transcription. Archaea serve as the natural host.^[2][3]
