Potato Virus T
''Tepovirus'' is a genus of viruses in the order ''Tymovirales ''Tymovirales'' is an order of viruses with five families. The group consists of viruses which have positive-sense, single-stranded RNA genomes. Their genetic material is protected by a special coat protein. Description Tymoviruses are mainly ...'', in the family '' Betaflexiviridae''. Plants as well as some other root and tuber crops in the andes serve as natural hosts. There are two species in this genus. Taxonomy The following species are assigned to the genus: *'' Potato virus T'' *'' Prunus virus 1'' Structure Viruses in ''Tepovirus'' are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm. Genomes are linear, around 6.5kb in length. The genome codes for 3 proteins. Life cycle Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive st ...

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.

Tymovirales
''Tymovirales'' is an order of viruses with five families. The group consists of viruses which have positive-sense, single-stranded RNA genomes. Their genetic material is protected by a special coat protein. Description Tymoviruses are mainly plant pathogens first described in 2004. They are characterised by similarities in their replication-associated polyproteins. These account for the majority of their genomic coding capacity. They are considered to form a group, phylogenetically, referred to as flexiviruses, with filamentous virions A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1 ....

Betaflexiviridae
''Betaflexiviridae'' is a family of viruses in the order ''Tymovirales''. Plants and fungi serve as natural hosts. There are 108 species in this family, assigned to 13 genera in two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms. Taxonomy The following subfamilies and genera are recognized: * ''Quinvirinae'' ** ''Carlavirus'' ** ''Foveavirus'' ** ''Robigovirus'' ** Plus three unassigned species: *** ''Banana mild mosaic virus'' *** ''Banana virus X'' *** ''Sugarcane striate mosaic-associated virus'' * ''Trivirinae'' ** ''Capillovirus'' ** ''Chordovirus'' ** ''Citrivirus'' ** ''Divavirus'' ** ''Prunevirus'' ** ''Ravavirus'' ** ''Tepovirus'' ** ''Trichovirus'' ** ''Vitivirus'' ** ''Wamavirus'' Structure Viruses in ''Betaflexiviridae'' are non-enveloped, with flexuous and Filamentous geometries. The diameter is approximately 12–13 nm. Genomes are linear, around 6.5–9kb in length. The genome codes for 2 to 6 proteins. Life cycle Vi ...

Prunus Virus 1
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Botany Members of the genus can be deciduous or evergreen. A few species ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virus Genera
A virus is a wikt:submicroscopic, submicroscopic infectious agent that replicates only inside the living Cell (biology), cells 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 often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisti ...
