Cauliflower mosaic virus (CaMV)
The virus is wide-spread and infects Brassica species and other crucifers. It causes leaf mosaic, necrosis, stunting and deformation. Cauliflower heads are reduced in size and unmarketable. Infections are favored by warm and dry conditions and the virus is transmitted by aphids in a non-persistent or semi-persistent manner. The virus survives in plant residues.
The particles are spherical, non-enveloped, and 50-53 nm in diameter. The genome is 8.0 kbp long and consists of circular dsDNA with 7 open reading frames and two integrated regions of 700 and 150 bp respectively. The CaMV 35S promoter is used in many transgenic crops because it efficiently activates foreign genes which have been inserted into the host plant.

CaMV is the type member of the genus Caulimovirus. Since it infects Arabidopsis thaliana it is also a popular model organism for biochemical studies.
