In the present invention, HPPD polypeptides and plants containing them showing a full tolerance against one or more HPPD inhibitor herbicides belonging to various chemical classes are described. A set of mutant HPPD polypeptides have been designed which have either no or only a significantly reduced affinity to HPPD inhibitor herbicides and, at the same time, the rate of dissociation of the HPPD inhibitors of the mutant HPPD polypeptide is increased to such an extent that the HPPD inhibitors no longer act as slow-binding or slow, tight-binding inhibitors but, instead of this, have become fully reversible inhibitors. In particular, isolated polynucleotides encoding mutant HPPD polypeptides conferring tolerance to HPPD inhibitor herbicides belonging to various chemical classes are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed.

HPPD variants and methods of use

In the present invention, HPPD enzymes and plants containing them showing a full tolerance against several classes of HPPD-inhibitors are described. A set of HPPD enzymes have been designed which have either no or only a significantly reduced affinity to HPPD inhibitors and, at the same time, the rate of dissociation of the HPPD inhibitors of the enzyme is increased to such an extent that the HPPD inhibitors no longer act as slow-binding or slow, tight-binding inhibitors but, instead of this, have become fully reversible inhibitors. In particular, isolated polynucleotides encoding HPPD inhibitor tolerance polypeptides are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed.

Compositions and methods for conferring herbicide tolerance to bacteria, plants, plant cells, tissues and seeds are provided. Compositions include polynucleotides encoding herbicide tolerance polypeptides, vectors comprising those polynucleotides, and host cells comprising the vectors. The nucleotide sequences of the invention can be used in DNA constructs or expression cassettes for transformation and expression in organisms, including microorganisms and plants. Compositions also include transformed bacteria, plants, plant cells, tissues, and seeds. In particular, isolated polynucleotides encoding HPPD inhibitor tolerance polypeptides are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed.
