Tymovirus Pomovirus TRNA-like 3' UTR Element
''Tymovirus'' is a genus of viruses in the order ''Tymovirales'', in the family ''Tymoviridae''. Plants serve as natural hosts. There are 28 species in this genus. Taxonomy The genus contains the following species: * ''Anagyris vein yellowing virus'' * ''Andean potato latent virus'' * ''Andean potato mild mosaic virus'' * '' Belladonna mottle virus'' * ''Cacao yellow mosaic virus'' * '' Calopogonium yellow vein virus'' * '' Chayote mosaic virus'' * '' Chiltepin yellow mosaic virus'' * '' Clitoria yellow vein virus'' * ''Desmodium yellow mottle virus'' * ''Dulcamara mottle virus'' * ''Eggplant mosaic virus'' * ''Erysimum latent virus'' * ''Kennedya yellow mosaic virus'' * ''Melon rugose mosaic virus'' * ''Nemesia ring necrosis virus'' * ''Okra mosaic virus'' * ''Ononis yellow mosaic virus'' * ''Passion fruit yellow mosaic virus'' * ''Peanut yellow mosaic virus'' * ''Petunia vein banding virus'' * ''Physalis mottle virus'' * ''Plantago mottle virus'' * ''Scrophularia mottle virus' ...

Turnip Yellow Mosaic Virus
''Turnip yellow mosaic virus'' (TYMV) is an isometric '' Tymovirus'' of the family '' Tymoviridae''. Its host range is confined almost entirely to plants in the genus ''Brassica'' in western Europe, which includes cabbages, cauliflower and broccoli. Infection causes bright yellow mosaic disease showing vein clearing and molting of plant tissues. Transmission It is transmitted by sap as well as a host of insect vectors. The most prominent of these are in the '' Phyllotreta'' and '' Psylliodes'' genera of flea beetles, although '' Phaedon cochleariae'' and its larva have also been known to help spread this virus. The larva lose their ability to transmit the disease once they reach the pupa A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their ...l stage, suggesting a mechanical infection ...

Clitoria Yellow Vein Virus
''Clitoria'' is a genus of mainly tropical and subtropical, insect-pollinated flowering pea vines. Taxonomy Naming of the genus This genus was named after the human clitoris, for the flowers bear a resemblance to the vulva. The first reference to the genus, which includes an illustration of the plant, was made in 1678 by Jakób Breyne, a Polish naturalist, who described it as ''Flos clitoridis ternatensibus'', meaning ' Ternatean flower of the clitoris'. Many vernacular names of these flowers in different languages are similarly based on references to female external genitalia. Controversies existed in the past among botanists regarding the good taste of the naming of the genus. The analogy drew sharp criticism from botanists such as James Edward Smith in 1807, Amos Eaton in 1817, Michel Étienne Descourtilz in 1826, and Eaton and Wright in 1840. Some less explicit alternatives, like ''Vexillaria'' (Eaton 1817) and ''Nauchea'' (Descourtilz 1826), were proposed, but they fail ...
