Pomovirus
''Pomovirus'' is a genus of viruses, in the family ''Virgaviridae''. Plants and dicotyledons serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: dwarfing of shoots (mop-top) and potato spraing disease. The name of the genus is derived from ''Potato mop-top virus'', ''Potato mop-top virus'', giving rise to ''Pomovirus''.Index of Viruses - Pomovirus (2006).

Virgaviridae
''Virgaviridae'' is a family of positive-strand RNA viruses. Plants serve as natural hosts.Adams MJ, Antoniw JF, Kreuze J (2009) Virgaviridae: a new family of rod-shaped plant viruses. Arch Virol 154(12):1967–1972 The name of the family is derived from the Latin word ''virga'' (rod), as all viruses in this family are rod-shaped. There are currently 59 species in this family, divided among seven genera. Structure Viruses in Virgaviridae are non-enveloped, with rigid helical rod geometries, and helical symmetry. The diameter is around 20-25 nm, and virions have a central "canal." Genomes are linear, single-stranded, positive sense RNA with a 3'-tRNA like structure and no polyA tail. They may be in one, two, or three segments, depending on the genus. Coat proteins are about 19–24 kiloDaltons. 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 ...

Potato Mop-top Virus
''Potato mop-top virus (PMTV)'' is a plant pathogenic virus transmitted through the vector ''Powdery scab, Spongospora subterranea'' that affects potatoes. PMTV belongs to family of ''Virgaviridae'', and the genus ''Pomovirus'' (Potato mop-top virus). The virus was first identified in 1966 by Calvert and Harrison in Britain, and is now reported in many other potato cultivating regions of the world including U.S.A., Canada, China, Pakistan, Japan, South American countries and many parts of Europe. Many disease management systems have been found to be ineffective against the virus, although a combination of sanitation and vector controls seems to work well. Hosts and symptoms As the name implies, the main host is potato; however, this virus also affects some common vegetable plants and weeds. Some of them include tomato, black nightshade, lambsquarters and ground cherry. The potato mop top virus' primary hosts are plants in the Solanaceae and Chenopodiaceae. Potatoes that are infe ...

Viruses
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 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'', consisting of (i) the genetic material, i.e ...

Dicotyledons
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dic ...

Beet Soil-borne Virus
The beetroot is the taproot portion of a beet plant, usually known in North America as beets while the vegetable is referred to as beetroot in British English, and also known as the table beet, garden beet, red beet, dinner beet or golden beet. It is one of several cultivated varieties of ''Beta vulgaris'' grown for their edible taproots and leaves (called beet greens); they have been classified as ''B. vulgaris'' subsp. ''vulgaris'' Conditiva Group. Other cultivars of the same species include the sugar beet, the leaf vegetable known as chard or spinach beet, and mangelwurzel, which is a fodder crop. Three subspecies are typically recognized. Etymology ''Beta'' is the ancient Latin name for beetroot,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 70 possibly of Celtic origin, becoming ''bete'' in Old English. ''Root'' derives from the late Old English ''rōt'', itself from Old Norse ''rót''.
