Macluravirus
''Macluravirus'' is a genus of viruses, in the family ''Potyviridae''. Plants serve as natural hosts. There are ten species in this genus. Description Similarly to other ''Potyviridae'' genera, ''Macluravirus'' is characterised by its flexuous filamentous particles, inclusion bodies in infected plant cells and a polyprotein genome strategy. Unlike the other genera it is transmitted by insects. It also has shorter particles (650-660 nm in length). The genomes are monopartite. The name is derived from member species ''Maclura mosaic virus ''Maclura'' is a genus of flowering plants in the mulberry family, Moraceae. It includes the inedible Osage orange, which is used as mosquito repellent and grown throughout the United States as a hedging plant. It is dioecious, with male a ...''. History The genus was proposed at the ICTV meeting in San Diego in 1998, and subsequently ratified.Pringle C.R. & Fauquet, C.M. (1998). ICTV announcement – ratification of new ta ...

Cardamom Mosaic Virus
The cardamom mosaic virus (CdMV) is a mosaic virus that affects the production of green cardamom ( ''E. cardamomum''). It is a member of the genus ''Macluravirus'' (recognized under the family '' Potyviridae'' by ICTV in 1988), and is transmitted through aphids (''P.'' ''caladii'') and infected rhizomes, the former in a non-persistent manner. Host and symptoms Green cardamom is one of the world's very ancient spices. Known as the “queen of spices”, because of their aroma and flavor, it is one of the most exotic and highly priced spices. It is the world's third most expensive spice after vanilla and saffron. Although India is the top producer of the spice, producing 31.1% of the world's cardamom followed by Guatemala and Nepal, Guatemala is the top exporter (exporting 43.6% of the world's cardamom) followed by Nepal and India. Cardamom suffers from several oomycetous, fungal, viral, nematode-induced diseases and pests that affect the productivity and the industry as a whole ...

Narcissus Latent Virus
Narcissus latent virus (NLV) is a Macluravirus, a plant pathogenic virus of the family ''Potyviridae'', which infects '' Narcissus''. Description Characterised by Brunt in 1976, it is found in Western Europe in '' Narcissus'', ''Nerine'' and bulbous irises. It is often accompanied by other plant viruses, and is transmitted by aphids Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A t .... It produces light and dark green mottling near the leaf tips. Taxonomy This '' Macluravirus'' should not be confused with the similarly named '' Narcissus common latent virus'' which is a '' Carlavirus'', and is sometimes incorrectly referred to by the name ''Narcissus latent virus''.

Potyviridae
''Potyviridae'' is a family of positive-strand RNA viruses that encompasses more than 30% of known plant viruses, many of which are of great agricultural significance. The family has 12 genera and 235 species, three of which are unassigned to a genus. Structure Potyvirid virions are nonenveloped, flexuous filamentous, rod-shaped particles. The diameter is around 12–15 nm, with a length of 200–300 nm. Genome Genomes are linear and usually nonsegmented, around 8–12kb in length, consisting of positive-sense RNA, which is surrounded by a protein coat made up of a single viral encoded protein called a capsid. All induce the formation of virus inclusion bodies called cylindrical inclusions (‘pinwheels’) in their hosts. These consist of a single protein (about 70 kDa) made in their hosts from a single viral genome product. Member viruses encode large polypeptides that are cleaved into mature proteins. In 5'–3' order these proteins are * P1 (a serine protease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artichoke Latent Virus
The globe artichoke (''Cynara cardunculus'' var. ''scolymus'' ),Rottenberg, A., and D. Zohary, 1996: "The wild ancestry of the cultivated artichoke." Genet. Res. Crop Evol. 43, 53–58. also known by the names French artichoke and green artichoke in the U.S., is a variety of a species of thistle cultivated as food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form. Another variety of the same species is the cardoon, a perennial plant native to the Mediterranean region. Both wild forms and cultivated varieties (cultivars) exist. Description This vegetable grows to tall, with arching, deeply lobed, silvery, glaucous-green leaves long. The flowers develop in a large head from an edible bud about diameter with numer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maclura Mosaic Virus
''Maclura'' is a genus of flowering plants in the mulberry family, Moraceae. It includes the inedible Osage orange, which is used as mosquito repellent and grown throughout the United States as a hedging plant. It is dioecious, with male and female flowers borne on separate plants. ''Maclura'' is closely related to the genus '' Cudrania'', and hybrids between the two genera have been produced. Some botanists recognize a more broadly defined ''Maclura'' that includes species previously included in ''Cudrania'' and other genera of Moraceae. The genus likely originated in South America during the Paleogene. Species * ''Maclura africana'' (Africa) * ''Maclura amboinensis'' (Myanmar to New Guinea) * ''Maclura andamanica'' (Vietnam, Laos to Andaman Islands) * ''Maclura brasiliensis'' (Brazil, Honduras, Nicaragua, Peru, and Venezuela) * ''Maclura cochinchinensis'' (Syn.: ''Cudrania cochinchinensis'', ''Cudrania javanensis'', ''Vanieria cochinchinensis'') (China, Vietnam, Malesia, ...

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 ...
