Abstract:
A protein derived from carrots can be used to regulate amino acid content in plants. The invention involves the isolation and purification of a bifunctional protein with aspartokinase and homserine activities. Other amino acids in the invention that can be used as plant regulators are lysine, homoserine, threonine, isoleuci and methionine. The invention also involves encoding a DNA molecule with a sequence that has the same structure of the bifunctional carrot protein. Further, the invention includes a method of regulating the amino acid content in a plant by bringing effective amounts of the bifunctional protein in contact with the plant.
