Cavemovirus

Cavemovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are currently only two species in this genus including the type species Carnation mottle virus. Diseases associated with this genus include: CMtV: carnation mottle.

Taxonomy

The following two species are assigned to the genus:

• Carnation mottle virus
• Spinach latent virus

Structure

Viruses in Cavemovirus are non-enveloped, with icosahedral and Round geometries, and T=3 symmetry. The diameter is around 28-30 nm. Genomes are linear, around 4kb in length.

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical.
