Pomovirus is a genus of viruses, in the family Virgaviridae.[1] 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.[1][2][3] The name of the genus is derived from Potato mop-top virus, giving rise to Pomovirus.[4]
The following species are assigned to the genus, listed by scientific name and followed by their common names:[3]
- Pomovirus betae, Beet virus Q
- Pomovirus colombiense, Colombian potato soil-borne virus
- Pomovirus solani, Potato mop-top virus
- Pomovirus solibetae, Beet soil-borne virus
- Pomovirus viciae, Broad bean necrosis virus
Structure
Viruses in the genus Pomovirus are non-enveloped, with rod-shaped geometries, and helical symmetry. The diameter is around 21 nm, with a length of 245 nm. Genomes are linear and segmented. The three segments are about 6, 3.5, and 3kb in length.[1][2]
