''. 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 virus
* ''Cavemovirus deltaepiphylli'',
Epiphyllum virus 4
* ''Cavemovirus 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 (RT) replication model. dsDNA (RT) 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 (aphid insects). Transmission routes are mechanical.
