  • Publication number: 20160040184
    Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest, as probes for the isolation of other homologous (or partially homologous) genes. The insecticidal proteins find use in controlling, inhibiting growth or killing lepidopteran, coleopteran, dipteran, fungal, hemipteran, and nematode pest populations and for producing compositions with insecticidal activity.

  • Patent number: 9187762
    Abstract: Compositions and methods comprising polynucleotides and polypeptides having 4-hydroxyphenylpyruvate dioxygenase (HPPD) activity and having insensitivity to an HPPD inhibitor are provided. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the HPPD sequences. Various methods of employing the HPPD sequences are provided. Such methods include, for example, methods for producing an HPPD inhibitor 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. Methods are also provided to identify additional HPPD variants. Further provided are various methods and compositions that allow the various HPPD polypeptides and variant and fragments thereof to be expressed in a chloroplast or transported to a chloroplast.

  • Publication number: 20120288914
    Abstract: The presently disclosed subject matter provides compositions and methods for evaluating the potential of candidate polypeptides to associate with glyphosate with a higher binding affinity, higher binding specificity, or both or to have N-acetyltransferase activity with a higher catalytic rate when compared to a native glyphosate acetyltransferase (GLYAT) polypeptide through the provision and comparison of three-dimensional molecular structures of the candidate polypeptides and the GLYAT polypeptides provided herein. The methods further provide for identification of polypeptides with these advantageous properties using the three-dimensional molecular structures of GLYAT polypeptides.
