Patents Assigned to E. I. Du Pont de Neumours and Company
  • Patent number: 8916746
    Abstract: Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring drought tolerance, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a DTP21 polypeptide.

  • Patent number: 8367899
    Abstract: The invention relates to methods and compositions for identifying maize plants that have newly conferred tolerance or enhanced tolerance to, or are susceptible to, Gray Leaf Spot (GLS). The methods use molecular genetic markers to identify, select and/or construct tolerant plants or identify and counter-select susceptible plants. Maize plants that display newly conferred tolerance or enhanced tolerance to GLS that are generated by the methods of the invention are also a feature of the invention.

  • Patent number: 8257930
    Abstract: Compositions and methods related to transgenic plants comprising seed production technology are provided. Specifically, maize plants having a E6611.32.1.38 event which confers seed production technology are provided. The plant harboring the E6611.32.1.38 event at the recited chromosomal location comprises the genomic/transgene junctions described. The plant genomic DNA flanking the integrated E6611.32.1.38 event can be used to design assays that will be specific for the E6611.32.1.38 event. The characterization of the genomic insertion site of the E6611.32.1.38 event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the maize E6611.32.1.38 event are provided.
