Dagazvirus
''Dagazvirus'' is a genus of viruses in the realm ''Ribozyviria'', containing the single species ''Dagazvirus schedorhinotermitis''. It is the only species within its realm known to be hosted by an invertebrate animal; the termite ''Schedorhinotermes intermedius ''Schedorhinotermes intermedius'' is a species of termite in the family Rhinotermitidae, endemic to eastern Australia.

Ribozyviria
''Ribozyviria'' is a realm of satellite nucleic acids. Established in ICTV TaxoProp 2020.012D, the realm is named after the presence of genomic and antigenomic ribozymes of the '' Deltavirus'' type. Additional common features include a rod-like structure, a RNA-binding "delta antigen" encoded in the genome, and animal hosts. Furthermore, the size range of the genomes of these viruses is between around 1547–1735nt, they encode a hammerhead ribozyme or a hepatitis delta virus ribozyme, and their coding capacity only involves one conserved protein. Most lineages of this realm are poorly understood, the notable exception being members of the genus ''Deltavirus'', the causal agents of Hepatitis D in humans. This realm of viruses have an unclear origin. They may have derived from retrozymes (a family of retrotransposons) or one of the other groups of mobile genetic elements that descended from retrozymes (i.e. viroids and satellites). But it was also proposed that they may h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schedorhinotermes Intermedius
''Schedorhinotermes intermedius'' is a species of termite in the family Rhinotermitidae, endemic to eastern Australia. Description Members of the worker caste possess internally serrated mandibles, a centrally grooved labrum, a fontanelle, and a flat pronotum with no anterior lobes. The soldier caste is dimorphic, with major and minor soldiers. The major soldier is 5.0–7.5 mm long, whereas the minor soldier is 3.0–5.0 mm long, with a narrower head, more slender mandibles, and longer labrum that extends to the tip of the mandibles. Distribution and habitat This species is distributed from south-eastern Queensland to just south of Sydney Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountain ..., mainly in coastal regions. In nature they build their nests in tree stumps, but the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Realm (virology)
In virology, realm is the highest taxonomic rank established for viruses by the International Committee on Taxonomy of Viruses (ICTV), which oversees virus taxonomy. Six virus realms are recognized and united by specific highly conserved traits: * '' Adnaviria'', which contains archaeal filamentous viruses with A-form double-stranded (ds) DNA genomes encoding a unique alpha-helical major capsid protein; * '' Duplodnaviria'', which contains all dsDNA viruses that encode the HK97-fold major capsid protein; * '' Monodnaviria'', which contains all single-stranded DNA (ssDNA) viruses that encode a HUH superfamily endonuclease and their descendants; * '' Riboviria'', which contains all RNA viruses that encode RNA-dependent RNA polymerase and all viruses that encode reverse transcriptase; * '' Ribozyviria'', which contains hepatitis delta-like viruses with circular, negative-sense ssRNA genomes; * and '' Varidnaviria'', which contains all dsDNA viruses that encode a vertical jell ...
