Patents by Inventor Wilf Keller

Wilf Keller 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: 7759547
    Abstract: The invention discloses methods for genetically transforming a plant so that it expresses a glycerol-3-phosphate dehydrogenase. The method raises levels glycerol-3-phosphate in comparison to the wild type, leading to increased stress tolerance, and altered fatty acid content in glycerolipids. The method also produces plants having improved phosphorus utilization.
    Type: Grant
    Filed: May 4, 2005
    Date of Patent: July 20, 2010
    Assignee: National Research Council of Canada
    Inventors: Jitao Zou, Wenyun Shen, Wilf Keller
  • Publication number: 20080189809
    Abstract: The present invention relates to methods for the use of the Arabidopsis “BREVIPEDICELLUS” (BP) gene for alteration of plant architecture, in particular alteration of the morphology of the inflorescence of a flowering plant. The methods of the present invention provide a means to alter the development of the peduncle, notably the inflorescence branches, and the pedicels that subtend the individual flowers as well as aspects of flower structure such as the style, and subsequent seed pods, of a flowering plant. The invention also relates to methods to identify and isolate polynucleotides encoding genes with BP-related functions from other plant species and methods for utilizing said polynucleotides to alter the inflorescence of said plant species. Furthermore, the invention encompasses transgenic plants generated by the methods disclosed, and nucleotide sequences for use in generating the transgenic plants.
