Abstract
The invention concerns a nucleic acid encoding a chimeric hydroxyphenyl pyruvate dehydrogenase (HPPD) enzyme formed from a nucleic acid encoding the N-terminal portion of a first plant HPPD in combination with nucleic acid encoding the C-terminal portion of a second plant HPPD, wherein the N-terminal portion and the C-terminal portion are separated by a linker peptide. The nucleic acid can be used to transfom a cell or an organism, such as a plant, to provide tolerance to herbicides. The invention also concerns methods of making and using plants transformed with the nucleic acid.
