Definition
Cauliflower mosaic virus (CaMV) is the type species of the family Caulimoviridae. This family is grouped together with Hepadnaviruses into the Pararetrovirus group dur to its mode of replication via reverse transcription of a pre-genomic RNA intermediate.
CaMV infects mostly plants of the Brassicaceae family (examples: Caulifower, 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, or stunding and deformation of the whole plant, whichvary depending on the viral strain, host ecotype and environmental conditions.
CaMV is transmitted in a no-circulated manner by aphid species such as Myzus persicae.Once introduced within a plant host cell, virions migrate to the nuclear envelope.

Famous quotes containing the word definition:
“The definition of good prose is proper words in their proper places; of good verse, the most proper words in their proper places. The propriety is in either case relative. The words in prose ought to express the intended meaning, and no more; if they attract attention to themselves, it is, in general, a fault.”
—Samuel Taylor Coleridge (1772–1834)
“It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.””
—Jane Adams (20th century)
“One definition of man is “an intelligence served by organs.””
—Ralph Waldo Emerson (1803–1882)
