Abstract Family Caulimoviridae comprises seven genera of plant viruses whose members replicate by reverse transcription and whose virions contain double‐stranded deoxyribonucleic acid . In a recent survey of the international scientific community, Cauliflower mosaic virus (CaMV), the type species of the family, was ranked sixth in the world in a list of the most scientifically or economically important plant viruses. This notoriety is due purely to the major conceptual advances that have been made in plant virology using CaMV as a model pathogen. However, several relatively lesser known viruses in the family, such as Rice tungro bacilliform virus and Cacao swollen shoot virus , are very serious constraints to crop production in tropical regions of the world. In this article, information on the taxonomy, replication cycle, vector transmission, epidemiology and disease management of this important group of plant viruses is summarised. Key Concepts: The Caulimoviridae is the only family of plant viruses with a double‐stranded deoxyribonucleic acid (dsDNA) genome, and in common with all viral retroelements, incorporates a reverse transcription step in the replication cycle. Cauliflower mosaic virus is the type species of the family, and has been a very important model plant virus for elucidating fundamental aspects of virus replication, cell‐to‐cell movement and aphid transmission. Members of the Caulimoviridae are most prominent in tropical regions, where they cause serious dise...
