Caulimovirus
# Caulimovirus

Caulimovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: vein-clearing or banding mosaic.

## Taxonomy

The genus contains the following species:

* Angelica bushy stunt virus
* Atractylodes mild mottle virus
* Carnation etched ring virus
* Cauliflower mosaic virus
* Dahlia mosaic virus
* Figwort mosaic virus
* Horseradish latent virus
* Lamium leaf distortion virus
* Mirabilis mosaic virus
* Soybean Putnam virus
* Strawberry vein banding virus
* Thistle mottle virus

## Structure

Viruses in Caulimovirus are non-enveloped, with icosahedral geometries, and T=7, T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented. The genome codes for 6 to 7 proteins.

## Life cycle

Viral replication is nuclear/cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA-RT replication model. DNA-templated transcription, specifically dsDNA-RT transcription is the method of transcription. Translation takes place by ribosomal shunting. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (aphid insects). Transmission routes are mechanical.
