Pomovirus is a genus of viruses, in the family Virgaviridae. Plants and dicotyledons serve as natural hosts. There are currently four species in this genus including the type species Potato mop-top virus. Diseases associated with this genus include: dwarfing of shoots (mop-top) and potato spraing disease. The name of the genus is derived from its type species, Potato mop-top virus, giving rise to Pomovirus.

Structure
Viruses in 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.
Life Cycle
Viral replication is cytoplasmic. 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 is the method of transcription. Translation takes place by suppression of termination. The virus exits the host cell by tripartite non-tubule guided viral movement. Plants and dicotyledons serve as the natural host. The virus is transmitted via a vector (fungus). Transmission routes are vector.
