Cavemovirus


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

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:Cavemovirus collusipomeae, Sweet potato collusive virusCavemovirus deltaepiphylli, Epiphyllum virus 4Cavemovirus venamanihotis, Cassava vein mosaic virus

Structure

Viruses in Cavemovirus are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented. The genome codes for 5 proteins.

Life cycle

Viral replication is nuclear/cytoplasmic. Replication follows the dsDNA replication model. dsDNA transcription is the method of transcription. 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. Transmission routes are mechanical.
