Structure

Viruses in ''Caulimovirus'' are non-enveloped, with icosahedral geometries, and T=7, T=7 symmetry. The diameter is around 50 nm. Genomes are circular and non-segmented. The genome codes for 6 to 7 proteins.

Life cycle

Viral replication is nuclear/cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA-RT replication model. DNA-templated transcription, specifically dsDNA-RT transcription is the method of transcription. Translation takes place by

ribosomal shunting Ribosome shunting is a mechanism of translation initiation in which ribosomes bypass, or "shunt over", parts of the 5' untranslated region to reach the start codon. However, a benefit of ribosomal shunting is that it can translate backwards allowing ...

. 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.
