The carrot (Daucus carota) gets its name from the French word carotte, which in turn comes from the Latin carota. It has been known since ancient times and is believed to have originated in Afghanistan and adjacent areas.
cDNA LIBRARIES: carrot flower buds and carrot seedlings mRNA USED FOR cDNA SYNTHESIS: total RNA was prepared from flower buds and 7-d-old seedlings of carrot (Daucus carota L. cv Nantaise) by the method described in Prescott and Martin, Plant Mol Biol Rep 4: 219-224, 1987.
A variant, WCHlO5, expressing CHr in the callus, as well as in regenerated plantlets, was isolated from a cell line derived from a wild carrot plant. The plantlets regenerated from WCHIO5 are green, but do not produce normal, dissected leaves.
CARROTS INTRODUCTION The carrot (Daucus carota L.) belongs to the family Apiaceae. It is related to celery, celeriac, coriander, fennel, parsnip and parsley, which are all members of this family. The carrot originated in Asia.
biennial that is closely related to garden carrots, but with a much reduced taproot. During the second year of growth, the plants produce stalks with white, flat-topped flowers.
