Prune Dwarf Virus

	Prune Dwarf Virus Prune dwarf virus (PDV) is a plant pathogenic virus of the family '' Bromoviridae''. It causes dwarfism of leaves on certain prune and plum plants. It will also cause yellows in sour cherry, especially when present with prunus necrotic ringspot virus ''Prunus necrotic ringspot virus'' (PNRSV) is a plant pathogenic virus causing ring spot diseases affecting species of the genus ''Prunus'', as well as other species such as rose (''Rosa'' spp.) and hops (''Humulus lupulus''). PNRSV is found worl .... There are no known transmission vectors, though the pollen of infected cherry trees has been found to infect other cherry trees a small percent of the time.

Structure Viruses in the family ''Bromoviridae'' are non-enveloped, with icosahedral and bacilliform geometries. The diameter is around 26-35 nm. Genomes are linear and segmented, tripartite. Life cycle Viral replication is cytoplasmic, and is lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription, using the internal ...

	Prunus Necrotic Ringspot Virus ''Prunus necrotic ringspot virus'' (PNRSV) is a plant pathogenic virus causing ring spot diseases affecting species of the genus ''Prunus'', as well as other species such as rose (''Rosa'' spp.) and hops (''Humulus lupulus''). PNRSV is found worldwide due to easy transmission through plant propagation methods and infected seed. The virus is in the family '' Bromoviridae'' and genus ''Ilarvirus''. Synonyms of PNRSV include European plum line pattern virus, hop B virus, hop C virus, plum line pattern virus, sour cherry necrotic ringspot virus, and peach ringspot virus. Hosts and symptoms All cultivated species of the genus ''Prunus'', which includes plums, cherries, apricots, almonds, and peaches, are susceptible to one or more strains of PNRSV. Hops and rose are also susceptible to infection by the virus. Other susceptible hosts used for diagnosis include ''Chenopodium quinoa'' Willd., sunflower (''Helianthus annus''), and ''Momordica balsamina''. Symptoms on orchard trees can ...
