Pomovirus

provided by wikipedia EN

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, Potato mop-top virus, giving rise to Pomovirus.[4]

Taxonomy

The following five species are assigned to the genus:[3]

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]

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.[1][2]
