    Assignees: Pioneer Hi-Bred International, Inc., E.I. du Pont de Nemours and Company
    Inventors: Ronald D. Flannagan, André Abad
  • Patent number: 7462760
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. The invention provides mutagenized nucleic acids that have been engineered to encode pesticidal polypeptides having increased resistance to proteolytic degradation by a plant protease. In particular, nucleic acid sequences encoding pesticidal polypeptides modified to comprise a proteolytic protection site that confers resistance to degradation or proteolytic inactivation by a plant protease are provided. Particular embodiments of the invention provide expression cassettes and transformed plants, plant cells, and seeds. These compositions find use in methods for protecting a plant from a pest.
    Type: Grant
    Filed: December 24, 2003
    Date of Patent: December 9, 2008
    Assignees: Pioneer Hi-Bred International, Inc., E.I. duPont de Nemours and Company
    Inventors: André Abad, Hua Dong, Rafael Herrmann, Albert Lu, Billy F. McCutchen, Janet A. Rice, Eric J. Schepers, James F. Wong
  • Patent number: 7378499
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. The invention provides mutagenized nucleic acids that have been engineered to encode pesticidal polypeptides having increased resistance to proteolytic degradation by a plant protease. In particular, nucleic acid sequences encoding pesticidal polypeptides modified to comprise a proteolytic protection site that confers resistance to degradation or proteolytic inactivation by a plant protease are provided. Particular embodiments of the invention provide pesticidal polypeptide compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds. These compositions find use in methods for controlling pests, especially plant pests. Novel plant proteases, sequences encoding these proteases, and methods for their use are also provided.
    Type: Grant

    Inventors: André Abad, Hua Dong, Rafael Herrmann, Albert Lu, Billy F. McCutchen, Janet Rice, Eric Schepers, James Wong
  • Patent number: 7105332
    Abstract: The invention provides nucleic acids, and variants and fragments thereof, obtained from strains of Bacillus thuringiensis encoding ?-endotoxins having pesticidal activity against insect pests. The invention further provides mutagenized nucleic acids that have been modified to encode pesticidal polypeptides such as endotoxins having improved pesticidal activity and/or altered pest specificity. Particular embodiments of the invention provide isolated nucleic acids encoding pesticidal proteins that may be optimized as well as pesticidal compositions, expression cassettes, and transformed microorganisms and plants comprising a nucleic acid of the invention. These compositions find use in methods for controlling pests, especially plant pests.
