Bromoviridae - A family of RNA plant viruses with a wide host range in crops and horticultural species. All viruses are readily transmitted by mechanical means and some by insects and pollen. The genera include: ALFAMOVIRUS; BROMOVIRUS; CUCUMOVIRUS; ILARVIRUS; and OLEAVIRUS. |
|
Carlavirus - A genus of RNA plant viruses, with unassigned family, containing slightly flexuous filaments, often transmitted by aphids in a non-persistent manner. Carnation latent virus is the type species. |
|
Closteroviridae - A family of plant viruses containing the largest single-stranded RNA genomes. Infections typically involve yellowing and necrosis, particularly affecting the phloem. |
|
Comoviridae - A family of non-enveloped RNA plant viruses, transmitted by biological vectors and experimentally by mechanical inoculation. There are three genera: COMOVIRUS; FABAVIRUS; and NEPOVIRUS. |
|
Luteovirus - A genus of plant viruses that infects both monocotyledonous and dicotyledonous plants. Its organisms are persistently transmitted by aphids, and weeds may provide reservoirs of infection. |
|
Mosaic Viruses - Viruses which produce a mottled appearance of the leaves of plants. |
|
Potexvirus - A genus of plant viruses that cause mosaic and ringspot symptoms. Transmission occurs mechanically. |
|
Potyviridae - A family of RNA plant viruses with flexuous, filamentous particles and consisting of three genera: POTYVIRUS, Rymovirus, and Bymovirus. A fourth genus, Ipomovirus, is possible. All members of the family form cytoplasmic cylindrical inclusion bodies during infection. |
|
Sequiviridae - A family of monopartite RNA plant viruses resembling picornaviruses and containing two genera: SEQUIVIRUS and WAIKAVIRUS. Transmission is by aphids or leafhoppers and requires a helper protein. |
|
Tenuivirus - A genus of RNA plant viruses as yet unassigned to any family. Plant hosts are all in the family Poaceae. Each species is transmitted by a particular species of planthopper. The type species is Rice stripe virus. |
|
Tombusviridae - A family of RNA plant viruses infecting dicotyledons. Transmission is mainly by mechanical inoculation and through propagative plant material. All species elicit formation of multivesicular inclusion bodies. There are at least eight genera: Aureusvirus, Avenavirus, CARMOVIRUS, Dianthovirus, Machlomovirus, Necrovirus, Panicovirus, and TOMBUSVIRUS. |
|
Tospovirus - A genus of plant viruses in the family BUNYAVIRIDAE. Tomato spotted wilt virus is the type species. Transmission occurs by at least nine species of thrips. |
