Caulimovirus (genus)
Caulimoviruses are similar to the Cauliflower mosaic virus (CaMV) which has been assigned to the species Caulimovirus tessellobrassicae. CaMV is economically important and infects a variety of crops from the family of Brassicaceae, compared to other viruses in this genus which usually have a more restricted host range. The viruses are transmitted by aphids in a semi persistent manner.
Like other Caulimoviridae, the particles of the viruses in this genus contain double-stranded DNA which is transcribed into RNA before being translated into proteins. During multiplication, the transcription is reversed to assemble the DNA genome in the particles. Such viruses are called pararetroviruses. The particles are isometric, not enveloped and about 45-50 nm in diameter. The DNA genome contains around 8000 base pairs and encodes 6 or 7 proteins.
Currently, the following species have been entered into the system:
