Patents by Inventor Gabriele Elfriede Dietrich

Gabriele Elfriede Dietrich 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).

  • Imidazolinone resistant AHAS mutants
    Patent number: 6444875
    Abstract: The present invention relates to mutant AHAS enzymes that are specifically resistant to imidazolinone herbicides. Exemplary of these is a corn sequence, which encodes an amino acid substitution at position 621 of the wild-type AHAS enzyme. Polynucleotides encoding the mutant enzyme can be used in screening methods for identifying plant cells that have been transformed.
    Type: Grant
    Filed: June 12, 1998
    Date of Patent: September 3, 2002
    Assignee: BASF Aktiengesellschaft
    Inventor: Gabriele Elfriede Dietrich
  • Imidazolinone resistant AHAS mutants
    Patent number: 5767361
    Abstract: The present invention relates to monocot genes encoding a mutant AHAS enzyme that is specifically resistant to imidazolinone herbicides. Exemplary of these genes are corn DNA sequences which encode an amino acid substitution at position 621 of the wild-type AHAS enzyme. The mutant gene can be used to transform other plants to herbicide resistance; in this regard, the invention also provides host cells and vectors containing the gene, which cells and vectors are useful in the transformation process.
