Patents by Inventor Dwayne Hegedus

Dwayne Hegedus 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: 7521595
    Abstract: The invention provides a method for selectively controlling the transcription of a gene of interest, comprising producing one or more plants that express either a first, a second, or both the first and second genetic constructs. The first genetic construct comprises a first regulatory region operatively linked to a gene of interest and at least one repressor sequence capable of controlling the activity of the first regulatory region. The second genetic construct comprises a second regulatory region in operative association with a nucleic acid molecule, or a derivative thereof, encoding a repressor protein, the repressor protein exhibiting both repressor operator sequence binding activity and repressor activity.
    Type: Grant
    Filed: November 23, 2004
    Date of Patent: April 21, 2009
    Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Agriculture and Agri-Food

The first genetic construct comprises a first regulator region operatively linked to a gene of interest and at least one repressor sequence capable of controlling the activity of the first regulatory region. The second genetic construct comprises a second regulator region in operative association with a nucleic acid molecule, or a derivative thereof, encoding a repressor protein, the repressor protein exhibiting both repressor operator sequence binding activity and repressor activity. The first and second genetic constructs may reside on separate vectors, or the vector may comprise both the first and second genetic constructs comprised as just defined.

  • Patent number: 7223855
    Abstract: The invention provides for a chimeric construct comprising a regulatory region obtained from a hydroperoxide lyase (HPL) gene in operative association with a heterologous gene of interest. Even though the HPL gene is known to be expressed in response to wounding, unexpectedly, it was observed that the HPL regulatory region or one or more fragments thereof, result in constitutive expression of the gene of interest in a range of tissues and organs in the absence of any wound or stress treatment. This invention also provides for a transgenic organism comprising the chimeric construct defined above, and a method for preparing a transgenic organism using the chimeric construct.
