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.

Chimeric hydroxyl-phenyl pyruvate dioxygenase, DNA sequence and method for obtaining plants containing such a gene, with herbicide tolerance

The present invention relates to a nucleic acid sequence encoding a mutated hydroxyphenylpyruvatedioxygenase (HPPD) which exhibits improved tolerance to HPPD inhibitors, to a chimeric gene which comprises this sequence as the coding sequence, and to its use for isolating or obtaining plants which are resistant to certain herbicides.
