Blueberry red ringspot virus, Carnation etched ring virus, Dahlia mosaic virus

Description and Significance

The cauliflower mosaic virus and related caulimoviridae viruses infect crucifers, groundnuts, soybeans, and cassava. The cauliflower mosaic virus promoter sequence is used to construct vectors to put genes into transgenic plants. When the virus attacks the host, signs and symptoms may persist or vary seasonally.

Genome Structure

The genome contains a single molecule of circular and is not segmented. The genoms is made of a double stranded DNA and is -RT. Virions do not contain minor species of non-genomic nucleic acid. The complete genome is about 8000 nucleotides long. The genome is sequenced but only an estimate is available. The complete sequence is 6800-7771-8175 nucleotides long.

The genome has a guanine+cytosine content of 28-35.5-43 %. It has single-stranded discontinuities at specific sites and the transcribed strand has at least one discontinuity while the non-trnascribed strand has two discontinuities. The genome may have an intergenic poly (A) region. (source: ICTV dB Descriptions)
