Patents by Inventor Bruce J. Drummond

Bruce J. Drummond 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).

  • Root-preferred regulatory elements
    Patent number: 8247649
    Abstract: The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions are novel nucleotide sequences for a root-preferred promoter and terminator isolated from the maize MSY coding region. A method for expressing a heterologous nucleotide sequence in a plant using the regulatory sequences disclosed herein is provided. The method comprises transforming a plant cell to comprise a heterologous nucleotide sequence operably linked to one or more of the regulatory sequences of the present invention and regenerating a stably transformed plant from the transformed plant cell.

  • RAD51 polypeptides
    Patent number: 6905857
    Abstract: Nucleic acid sequences encoding two RAD51 recombinases active in maize plants are provided. cDNA sequences including the ZmRAD51 coding sequences and unique 3?-untranslated regions which are useful as RFLP probes, are also provided. The production of plasmids containing a nucleic acid sequence encoding a ZmRAD51 fusion protein, as well as the use of the plasmids to introduce the ZmRAD51 coding sequence into a host cell, such as maize cell, are also disclosed.

  • Nucleic acid sequence encoding FLP recombinase
    Patent number: 6720475
    Abstract: A nucleic acid sequence effectively expressing FLP recombinase in monocot plants, particularly in maize. Stable, transformed maize plants harboring a gene encoding FLP or harboring FRT nucleic acid sequences enable efficient site-directed recombination of nucleic acid sequences in a monocot's genome.
