Caulimovirus (genus)

Caulimoviruses are similar to the Cauliflower mosaic virus which is also the most important species of this genus and infects a variety of crops from the family of Brassicaceae. Other species have usually a more restricted host range. The viruses are transmitted by aphids in a semi persistent manner.

Like other Caulimoviridae and the Geminiviridae the Caulimoviruses contain double-stranded DNA which is transcribed into RNA before being translated into proteins. During multiplication the transcription is reversed (pararetroviruses). The particles are isometric, not enveloped and 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:
