Assignee:

PIONEER HI-BRED INTERNATIONAL, INC. - JOHNSTON IA

International Classification:

C12N 15/82
C12N 9/10

Abstract:

Compositions and methods comprising polynucleotides and polypeptides having EPSP (5-enolpyruvylshikimate-3-phosphate) synthase (EPSPS) activity are provided. In specific embodiments, the sequence has an improved property, such as, but not limited to, improved catalytic capacity in the presence of the inhibitor, glyphosate. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the EPSPS sequences. Various methods of employing the EPSPS sequences are provided. Such methods include methods for producing a glyphosate tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein.
