cauliflower mosaic virus
Cauliflower mosaic virus (CaMV) is a member of the genus ''Caulimovirus'', one of the six genera in the ''Caulimoviridae'' family, which are pararetroviruses that infect plants. Pararetroviruses replicate through reverse transcription just like retroviruses, but the viral particles contain DNA instead of RNA.
== Definition==
Cauliflower mosaic virus (CaMV) is the type species of the family ''Caulimoviridae''. This family is grouped together with ''Hepadnaviruses'' into the ''Pararetrovirus'' group due to its mode of replication via reverse transcription of a pre-genomic RNA intermediate.
CaMV infects mostly plants of the ''Brassicaceae'' family (such as cauliflower and turnip) but some CaMV strains (D4 and W260) are also able to infect ''Solanaceae'' species of the genera ''Datura'' and ''Nicotiana''. CaMV induces a variety of systemic symptoms such as mosaic, necrotic lesions on leaf surfaces, stunted growth, and deformation of the overall plant structure. The symptoms exhibited vary depending on the viral strain, host ecotype, and environmental conditions.
CaMV is transmitted in a non-circulatory manner by aphid species such as ''Myzus persicae''. Once introduced within a plant host cell, virions migrate to the nuclear envelope of the plant cell.
