Abstract
Compositions and methods for conferring herbicide resistance to and improving nitrogen utilization of bacteria, plants, plant cells, tissues and seeds are provided. Compositions comprising a coding sequence for a polypeptide that confers resistance or tolerance to herbicidal glutamine synthetase inhibitors are provided. The coding sequences can be used in DNA constructs or expression cassettes for transformation and expression in plants. Compositions also comprise transformed bacteria, plants, plant cells, tissues, and seeds. In particular, isolated polynucleotides corresponding to herbicidal glutamine synthetase inhibitor-resistant polynucleotides are provided. Additionally, polypeptides corresponding to the polynucleotides are encompassed. In particular, the present invention provides for isolated polynucleotides comprising a variant of SEQ ID NO:1, wherein the variant polynucleotide encodes a polypeptide that is resistant to inhibition by herbicidal glutamine synthetase inhibitor.
