Patent number: 8188036Abstract: The invention provides nucleic acids, and variants and fragments thereof, obtained from strains of Bacillus thuringiensis encoding ?-endotoxins having pesticidal activity against pests of the order Coleoptera. The invention further provides mutagenized nucleic acids that have been modified to encode endotoxins having improved pesticidal activity and/or altered pest specificity. Particular embodiments of the invention provide isolated nucleic acids encoding pesticidal proteins, 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.Type: GrantFiled: May 27, 2009Date of Patent: May 29, 2012Assignee: E.I. du Pont de Nemours and CompanyInventors: Andre R. Abad, Nicholas B. Duck, Xiang Feng, Ronald D. Flannagan, Theodore W. Kahn, Lynne E. Sims

Patent number: 7803925Abstract: Compositions and methods for conferring pesticidal activity to bacteria, plants, plant cells, tissues and seeds are provided. Compositions comprising a coding sequence for a delta-endotoxin polypeptide are provided. The coding sequences can be used in DNA constructs or expression cassettes for transformation and expression in plants and bacteria. Compositions also comprise transformed bacteria, plants, plant cells, tissues, and seeds. In particular, isolated delta-endotoxin nucleic acid molecules are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed. In particular, the present invention provides for isolated nucleic acid molecules comprising nucleotide sequences encoding the amino acid sequence shown in SEQ ID NO:2, 4, 15, 17, or 19, or the nucleotide sequence set forth in SEQ ID NO:1, 3, 14, 16, or 18, as well as variants and fragments thereof.Type: GrantFiled: July 1, 2008Date of Patent: September 28, 2010Assignee: Athenix Corp.Inventors: Nadine Carozzi, Michael G. Koziel, Tracy Hargiss, Nicholas B. Duck, Theodore W. Kahn
