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. [1] [2]
The genus contains the following species: [2]
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]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Cavemovirus | Icosahedral | T=7 | Non-enveloped | Circular | Monopartite |
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]

Caulimoviridae is a family of viruses infecting plants. There are 94 species in this family, assigned to 11 genera. Viruses belonging to the family Caulimoviridae are termed double-stranded DNA (dsDNA) reverse-transcribing viruses i.e. viruses that contain a reverse transcription stage in their replication cycle. This family contains all plant viruses with a dsDNA genome that have a reverse transcribing phase in their lifecycle.
Closteroviridae is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
Sequivirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: PYFV: vein-yellowing, yellow flecks and yellow/green mosaic symptoms in parsnip, and ‘yellow net', followed by yellow spots and leaf distortion in celery.
Avihepadnavirus is a genus of viruses, in the family Hepadnaviridae. Birds serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: hepatitis, hepatocellular carcinomas, and cirrhosis.
Petuvirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There is only one species in this genus: Petunia vein clearing virus. Diseases associated with this genus include: plants: chlorotic vein clearing, leaf malformation.
Iltovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Alphaherpesvirinae. Birds, galliform birds, psittacine birds, chickens, turkeys, and quail serve as natural hosts. There are only two species in this genus. Diseases associated with this genus include: acute respiratory diseases: gaHV-1: infectious laryngotracheitis; psHV-1: Pacheco's disease.
Orthohepadnavirus is a genus of viruses, in the family Hepadnaviridae. Humans and other mammals serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: hepatitis, hepatocellular carcinoma, and cirrhosis.
