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:
“No man, not even a doctor, ever gives any other definition of what a nurse should be than this—”devoted and obedient.” This definition would do just as well for a porter. It might even do for a horse. It would not do for a policeman.”
—Florence Nightingale (1820–1910)
“The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”
—William James (1842–1910)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
