cavemovirus 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. cavemovirus virus classification (unranked): virus realm: riboviria kingdom: pararnavirae phylum: artverviricota class: revtraviricetes order: ortervirales family: caulimoviridae genus: cavemovirus taxonomy the genus contains the following species: cassava vein mosaic virus epiphyllum virus 4 sweet potato collusive 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. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation cavemovirusicosahedralt=7non-envelopedcircularmonopartite 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. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission cavemovirusplantsnoneviral movement; mechanical inoculationviral movementnucleuscytoplasmmechanical inoculation: aphids
