Patents by Inventor Hugo K. Dooner

Hugo K. Dooner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6184355
    Abstract: The present invention provides polynucleotide sequences from FAE1 genes. FAE1 genes encode elongation enzymes which catalyze the conversion of C18 FAs to C20-C22 FAs. The polynucleotides of the invention are used to modify FAE1 gene expression and thereby modulate FA content in plant organs or parts, particularly seeds.
    Type: Grant
    Filed: July 21, 1999
    Date of Patent: February 6, 2001
    Assignee: Cargill Incorporated
    Inventors: Douglas W. James, Jr., Eda Lim, Janis Keller, Hugo K. Dooner

  • Patent number: 5910627
    Abstract: The present invention provides compositions and methods for regulating vacuolar pH. Isolated DNA constructs comprising sequences substantially identical to a Ph gene are provided. The methods typically involve introducing the construct into a plant, whereby vacuolar pH is modified in the transgenic plant.
    Type: Grant
    Filed: February 16, 1996
    Date of Patent: June 8, 1999
    Assignee: DNA Plant Technology Corporation

  • Patent number: 5773693
    Abstract: Polynucleotides encoding Pea ADP-glucose pyrophosphorylase subunits are provided that are useful for changing the phenotype of higher plants, especially the garden pea (Pisum sativum L.) and other legumes, in regard to starch and sucrose biosynthesis. In particular, the invention relates to affecting the sucrose and starch content of edible plants.
    Type: Grant
    Filed: December 22, 1995
    Date of Patent: June 30, 1998
    Assignee: DNAP Plant Technology Corporation
    Inventors: Diane G. Burgess, Hugo K. Dooner
