摘要

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