Betaguttavirus is a genus of viruses, in the family Guttaviridae . Aeropyrum pernix archaea serve as natural hosts. There is only one species in this genus: Aeropyrum pernix ovoid virus 1. [1] [2] [3]
Viruses in the genus Betaguttavirus are enveloped. The diameter is around 70-55 nm. Genomes are circular. [2] [3]
DNA-templated transcription is the method of transcription. Aeropyrum pernix archaea serve as the natural host. Transmission routes are passive diffusion. [2] [3]
Benyvirus is a genus of viruses, in the family Benyviridae. Plants serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.
Lipothrixviridae is a family of viruses in the order Ligamenvirales. Thermophilic archaea in the phylum Thermoproteota serve as natural hosts. There are 11 species in this family, assigned to 4 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'.
Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus serve as natural hosts. There are four species in this family, assigned to a single genus, Alphaglobulovirus.
Secoviridae is a family of viruses in the order Picornavirales. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. The family was created in 2009 with the grouping of families Sequiviridae, now dissolved, and Comoviridae, now subfamily Comovirinae, along with the then unassigned genera Cheravirus, Sadwavirus, and Torradovirus.
Bottigliavirus is the only genus in the family Ampullaviridae and contains 3 species. Ampullaviridae infect archaea of the genus Acidianus. The name of the family and genus is derived from the Latin word for bottle, ampulla, due to the virions having the shape of a bottle. The family was first described during an investigation of the microbial flora of hot springs in Italy.
Bicaudaviridae is a family of hyperthermophilic archaeal viruses. Members of the genus Acidianus serve as natural hosts. There is only one genus, Bicaudavirus, and one species, Acidianus two-tailed virus, in this family. However, Sulfolobus tengchongensis spindle-shaped viruses 1 and 2 are regarded to belong to this family also.
Clavaviridae is a family of double-stranded viruses that infect archaea. This family was first described by the team led by D. Prangishvili in 2010. There is one genus in this family (Clavavirus). Within this genus, a single species has been described to date: Aeropyrum pernix bacilliform virus 1 (APBV1).
David Prangishvili is a virologist, Professor at the Pasteur Institute of Paris, and foremost authority on viruses infecting Archaea.
Tevenvirinae is a subfamily of viruses in the order Caudovirales, in the family Myoviridae. Bacteria and archaea serve as natural hosts. There are 135 species in this subfamily, most included in 12 genera.
Myohalovirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria and archaea serve as natural hosts. There are three species in this genus.
Psimunavirus is a genus of viruses in the family Siphoviridae. Bacteria and archaea serve as the natural host, with transmission achieved through passive diffusion. There is only one species in this genus: Psimunavirus psiM2.
Alphaguttavirus is a genus of viruses, in the family Guttaviridae. Sulfolobus newzealandicus serve as natural hosts. There is only one species in this genus: Sulfolobus newzealandicus droplet-shaped virus.
Tristromaviridae is a family of viruses. Archaea of the genera Thermoproteus and Pyrobaculum serve as natural hosts. Tristromaviridae is the sole family in the order Primavirales. There are two genera and three species in the family.
Deltalipothrixvirus is a genus of viruses in the family Lipothrixviridae. Archaea acidianus serve as natural hosts. Two species are assigned to the genus.
Captovirus is a genus of viruses in the family Ungulaviridae. Archaea acidianus serve as natural hosts. There is only one species in this genus: Captovirus AFV1, also known as Acidianus filamentous virus 1.
Iridovirus is a genus of viruses in the family Iridoviridae. Insects serve as natural hosts. Currently, only two species are placed in this genus. Invertebrate iridescent virus 6 (IIV-6) was recognised as the type species until such a designation was abolished. IIV-6 is hosted by mosquitos and usually causes covert (inapparent) infection that reduces fitness. The remaining species Invertebrate iridescent virus 31 (IIV-31) is hosted by isopods and causes patent (apparent) infection characterised by blue to bluish-purple iridescence and a shortened lifespan.
Turriviridae is a family of viruses; it contains only one genus, Alphaturrivirus. The archaea Sulfolobus solfataricus serve as natural hosts. There are two species in the genus Alphaturrivirus.
Cryspovirus is a genus of viruses, in the family Partitiviridae. Protists serve as natural hosts. There is only one species in this genus: Cryptosporidium parvum virus 1.
Spiraviridae is a family of incertae sedis viruses that replicate in hyperthermophilic archaea of the genus Aeropyrum, specifically Aeropyrum pernix. The family contains one genus, Alphaspiravirus, which contains one species, Aeropyrum coil-shaped virus. The virions of ACV are non-enveloped and in the shape of hollow cylinders that are formed by a coiling fiber that consists of two intertwining halves of the circular DNA strand inside a capsid. An appendage protrudes from each end of the cylindrical virion. The viral genome is ssDNA(+) and encodes for significantly more genes than other known ssDNA viruses. ACV is also unique in that it appears to lack its own enzymes to aid replication, instead likely using the host cell's replisomes. ACV has no known relation to any other archaea-infecting viruses, but it does share its coil-like morphology with some other archaeal viruses, suggesting that such viruses may be an ancient lineage that only infect archaea.
