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 ...

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] |
Bufo Gargarizans
The Asiatic toad or Chusan Island toad (''Bufo gargarizans'') is a species of toad endemic to East Asia. The species was previously classified as ''Bufo bufo gargarizans'', a subspecies of the common toad. Distribution and habitat It is common in China (specifically Anhui, Fujian, Gansu, Guizhou, Hebei, Heilongjiang, Henan, Hubei, Hunan, Inner Mongolia, Jiangsu, Jiangxi, Jilin, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, and Zhejiang) and portions of the Russian Far East (up north to the Amur River valley and on Sakhalin Island, and east to Transbaikalia in Siberia), but relatively rare on the Korean Peninsula. Asiatic toads are also found on the Miyako Islands of southern Japan, although they have been extirpated from some islands in recent years, possibly including Okinawa. The Miyako subspecies, ''Bufo gargarizans miyakonis'', is also known as the Miyako toad. The Asiatic toad avoids dense forests, but is found in most other habitat In ecology, the term habita ...
