Bicaudaviridae
''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 in this family: ''Acidianus two-tailed virus''. However, Sulfolobus tengchongensis spindle-shaped viruses 1 and 2 ( STSV1 and STSV2) are regarded to belong to this family also. Taxonomy The genus contains one genus, which contains one species: * ''Bicaudavirus'' ** ''Acidianus two-tailed virus'' Structure Viruses in ''Bicaudaviridae'' are non-enveloped, with lemon-shaped geometries. Genomes are circular dsDNA molecules of around 48–76 kb in length. High-resolution structure was determined by cryo-EM for Sulfolobus monocaudavirus 1 (SMV1) and a lower-resolution structure was determined for Acidianus two-tailed virus (ATV). Virions of both viruses have helical symmetry, with continuous 7-start helices, composed of the single major capsid protein, forming both the tails and the spindle-shaped b ...

Sulfolobus Tengchongensis Spindle-shaped Virus
Sulfolobus tengchongensis spindle-shaped virus 1 (STSV1) is a DNA virus of the family ''Bicaudaviridae''. It infects the hyperthermophilic archaeon '' Sulfolobus tengchongensis'' which can be found in the volcanic area of Tengchong, Baoshan City, in western Yunnan province, People's Republic of China. In 2014, Sulfolobus tengchongensis spindle-shaped virus 2 (STSV2), a relative of STSV1, also infecting ''S. tengchongensis'', has been reported. Besides ''S. tengchongensis'', STSV2 infects ''Sulfolobus islandicus'' REY15A. It has been demonstrated that STSV2 induces unprecedented gigantism of ''S. islandicus'' cells by blocking the expression of the cell division genes and arresting the cell cycle in the S phase. The diameter of infected cells increases up to 20 times, resulting in 8,000-fold increase in volume compared to noninfected cells.

David Prangishvili
David Prangishvili (born 1948) is a virologist, Professor at the Pasteur Institute of Paris, and foremost authority on viruses infecting Archaea. Biography David Prangishvili gained a Master of Science degree in 1971 at Tbilisi State University, Georgia, and a PhD (1977) and Habilitation (1989) from Institute of Molecular Biology of the USSR Academy of Sciences, Moscow. He pioneered research on Archaea, the third domain of life, in the USSR and in 1986-1991 was a head of the department of Molecular Biology of Archaea at the Georgian Academy of Sciences, Tbilisi. In 1991-2004 he has worked in Germany, at Max-Planck Institute for Biochemistry and at Regensburg University. Since 2004 he is working at the Pasteur Institute of Paris. David Prangishvili received a prize of Council of Ministers of the USSR for Excellence in Science and Technology in 1979.

Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells Cell most often refers to: * Cell (biology), the functional basic unit of life Cell may also refer to: Locations * Monastic cell, a small room, hut, or cave in which a religious recluse lives, alternatively the small precursor of a monastery w ... of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...
