Abacá Bract Mosaic Virus
Abaca bract mosaic virus (ABrMV) is a plant pathogenic virus of the family Potyviridae. Attempts have been made to sequence ABrMV. The virus is said to be a significant pathogen of the abaca, along with the Abaca bunchy top virus. Banana bract mosaic virus Banana bract mosaic virus (BBrMV) is a plant pathogenic virus Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate with ... also infects the abaca, but it is unknown whether the two viruses are related. Another source describes the main viral pathogens of the abaca as the banana bract mosaic virus and the sugarcane mosaic virus, without mentioning this name at all.

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] |
Potyvirus
''Potyvirus'' is a genus of positive-strand RNA viruses in the family ''Potyviridae''. Plants serve as natural hosts. The genus is named after member virus ''potato virus Y''. Potyviruses account for about thirty percent of the currently known plant viruses. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and ornamental crops. More than 200 species of aphids spread potyviruses, and most are from the subfamily ''Aphidinae'' (genera ''Macrosiphum'' and ''Myzus''). The genus contains 190 species. Virology Structure The virion is non-enveloped with a flexuous and filamentous nucleocapsid, 680 to 900 nanometers (nm) long and is 11–20 nm in diameter. The nucleocapsid contains around 2000 copies of the capsid protein. The symmetry of the nucleocapsid is helical with a pitch of 3.4 nm. Genome The genome is a linear, positive-sense, single-stranded RNA ranging in size from 9,000–12,000 nucleotide bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Virus
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to higher plants. Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope. The great majority have an RNA genome, which is usually small and single stranded (ss), but some viruses have double-stranded (ds) RNA, ssDNA or dsDNA genomes. Although plant viruses are not as well understood as their animal counterparts, one plant virus has become very recognizable: ''tobacco mosaic virus'' (TMV), the first virus to be discovered. This and other viruses cause an estimated US$60 billion loss in crop yields worldwide each year. Plant viruses are grouped into 73 genera and 49 families. However, these figures relate only to cultivated plants, which r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abaca Bunchy Top Virus
Abaca bunchy top virus (ABTV) is a pathogenic plant virus of the family ''Nanoviridae''. ABTV has been isolated from both abacá (''Musa textilis'') and banana (Musa sp.). ABTV has many similarities to banana bunchy top virus (BBTV) but is both genetically and serologically distinct in that it lacks two open reading frames found in BBTV's genome. ATBV's genome contains six circular components, each of which are 1,000-1,500 base pairs in length. __TOC__ Spread The virus, first detected in 1915 at Silang, Cavite, Philippines, has since spread to various provinces in the country, and damaged more than of abacá plantations in 2002 alone. Resistance In 2009, University of the Philippines Los Baños researchers funded by the Department of Agriculture developed an abacá variety that is resistant to the ABTV. The university is working further to make it resistant to mosaic and abacá bract mosaic virus Abaca bract mosaic virus (ABrMV) is a plant pathogenic virus of the family ...

Sugarcane Mosaic Virus
''Sugarcane mosaic virus'' (SCMV) is a plant pathogenic virus of the family '' Potyviridae''. The virus was first noticed in Puerto Rico in 1916 and spread rapidly throughout the southern United States in the early 1920s. SCMV is of great concern because of the high economic impact it has on sugarcane and maize. Hosts Sugarcane mosaic virus causes mosaic symptoms in sugarcane, maize, sorghum, and other poaceous plants. In sugarcane, this is the most widespread virus and 21 strains of it have been found in the United States. The SCMV complex has been shown to consist of four distinct potyviruses and includes strains of ''Johnsongrass mosaic virus'' (JGMV), '' maize dwarf mosaic virus'' (MDMV), ''sorghum mosaic virus ''Sorghum mosaic virus'' (SrMV) is a plant pathogenic virus of the family '' Potyviridae''.
