Patents by Inventor Christopher Zinselmeier

Christopher Zinselmeier 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).

  • Enhanced floral sink strength and increased stability of seed set in plants
    Patent number: 8026411
    Abstract: The invention discloses a transgenic method for enhancing sink strength in female reproductive organs. It involves the temporal and spatial expression of genes affecting the starch and sucrose metabolic pathways in a plant organ or plant tissue. The invention also includes expression constructs, and methods for the production of crop plants with heritable phenotypes which are useful in breeding programs designed to increase yield potential over a range of environmental conditions.
    Type: Grant
    Filed: November 20, 2009
    Date of Patent: September 27, 2011
    Assignee: Pioneer Hi-Bred International, Inc.
    Inventors: Dwight T. Tomes, Christopher Zinselmeier, Jeffrey E. Habben
  • Enhanced silk exsertion under stress
    Patent number: 8017834
    Abstract: The invention provides methods for enhancing maize silk exsertion under stress conditions and compositions relating to such methods, including nucleic acids and proteins. The invention further provides recombinant expression cassettes, host cells, and transgenic plants.
