Cavemovirus

Cavemovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are currently only two species in this genus including the type species Cassava vein mosaic virus. Diseases associated with this genus include: vein-clearing or banding mosaic.[1][2]

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.[1]

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.[1]
