Broad bean wilt virus 1 (BBWVI) is a plant pathogenic virus of the order Picornavirales , family Secoviridae , subfamily Comovirinae , genus Fabavirus . [1]
BBWV was first isolated from broad beans ( Vicia faba ) in Australia in 1947, and is transmitted by aphids. Despite its name, BBWV has a wide range of hosts including both monocotyledons and dicotyledons, but mainly the latter. By 1991 177 species in 39 families had been reported as being infected with BBWV. These include perennial bulbous ornamentals such as Narcissus tazetta . [2] [3]
Broad bean wilt virus 1 is one of two similar species (BBWV) of a total of seven in the genus Fabavirus, the other being Broad bean wilt virus 2. Proposed as a member of the Fabavirus group in 1987, its current taxonomic status was established in 2009 in the (current) 9th report of the ICTV. [1]
Narcissus is a genus of predominantly spring flowering perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil, narcissus and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and yellow, with either uniform or contrasting coloured tepals and corona.
Comovirinae is a subfamily of viruses in the order Picornavirales, in the family Secoviridae; its genera were formerly classified in the family Comoviridae. Plants serve as natural hosts. There are 62 species in this subfamily, assigned to 3 genera.
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.
The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclatures for viruses. The ICTV has developed a universal taxonomic scheme for viruses, and thus has the means to appropriately describe, name, and classify every virus that affects living organisms. The members of the International Committee on Taxonomy of Viruses are considered expert virologists. The ICTV was formed from and is governed by the Virology Division of the International Union of Microbiological Societies. Detailed work, such as delimiting the boundaries of species within a family, typically is performed by study groups of experts in the families.
Potyvirus is a genus of viruses in the family Potyviridae. Plants serve as natural hosts. There are 190 species in this genus. The genus is named after member virus potato virus Y. Potyviruses account for ~30% 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.
Carmovirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are currently 19 species in this genus including the type species Carnation mottle virus. It is classified under the Baltimore classification system as a group IV virus, having a single-stranded, positive-sense RNA genome.
Cucumber mosaic virus (CMV) is a plant pathogenic virus in the family Bromoviridae. This virus has a worldwide distribution and a very wide host range. In fact it has the reputation of having the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, Cuscuta sp. (dodder).
Orthotospovirus is a genus of negative-strand RNA viruses, in the family Tospoviridae of the order Bunyavirales, which infects plants. Tospoviruses take their name from the species Tomato spotted wilt orthotospovirus (TSWV) which was discovered in Australia in 1919. TSWV remained the only member of the family until the early 1990s when genetic characterisation of plant viruses became more common. There are now at least twenty species in the genus with more being discovered on a regular basis. Member viruses infect over eight hundred plant species from 82 different families.
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.
Carlavirus, formerly known as the "Carnation latent virus group", is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are 53 species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms.
Secoviridae is a family of viruses in the order Picornavirales. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. The family was created in 2009 with the grouping of families Sequiviridae, now dissolved, and Comoviridae, now subfamily Comovirinae, along with the then unassigned genera Cheravirus, Sadwavirus, and Torradovirus.
Protoparvovirus is a genus of viruses in the Parvovirinae subfamily of the virus family Parvoviridae. Vertebrates serve as natural hosts. There are 15 species in the genus including Rodent protoparvovirus 1 for which the exemplar virus is minute virus of mice (MVM). This genus also includes canine parvovirus (CPV), which causes gastrointestinal tract damage in puppies that is about 80% fatal, and porcine parvovirus (PPV), which is a major cause of fetal death and infertility in pigs. The genus divides phylogenetically into two branches, one that contains many founder members of the family, such as MVM, CPV and PPV, which have been studied in considerable detail, and a second branch occupied exclusively by predicted viruses whose coding sequences were identified recently in the wild using virus discovery approaches, but whose biology remains minimally explored. This second branch currently contains two species whose members infect humans, called Primate protoparvovirus 1 and Primate protoparvovirus 3. Until 2014, the genus was called Parvovirus, but it was renamed to eliminate confusion between members of this genus and members of the entire family Parvoviridae.
Narcissus yellow stripe potyvirus (NYSV) is a plant pathogenic Potyvirus of the family Potyviridae which infects plants of the genus Narcissus. It is one of the commoner viruses infecting Narcissus, and is transmitted by aphids.
Fabavirus is a genus of plant viruses in the order Picornavirales, in the family Secoviridae, in the subfamily Comovirinae. Plants serve as natural hosts. There are seven species in this genus.
Narcissus tip necrosis virus (NTNV) is a plant pathogenic virus of the family Tombusviridae, which infects plants of the genus Narcissus, the only known host.
Ampelovirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are 13 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.
Comovirus is a genus of viruses in the order Picornavirales, in the family Secoviridae, in the subfamily Comovirinae. Plants serve as natural hosts. There are 15 species in this genus.
Nanovirus is a genus of viruses, in the family Nanoviridae. Legume plants serve as natural hosts. There are 11 species in this genus. Diseases associated with this genus include: stunting, severe necrosis and early plant death.
Nyamiviridae is a family of negative-strand RNA viruses in the order Mononegavirales. Ecdysozoa and birds serve as natural hosts. The name is a portmanteau of Nyamanini Pan and Midway Atoll and the suffix -viridae used to denote a virus family. There are seven genera in this family.
Peribunyaviridae is a family of viruses in the order Bunyavirales. Its name partially derives from Bunyamwera, Uganda, where the founding species was first isolated.
