David A. Tepfer 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).

  • Ri T-DNA promoters
    Patent number: 5824866
    Abstract: The sequence of the T.sub.L -DNA of Ri plasmids found in Agrobacterium rhizogenes strains HRI and A4 is disclosed. Sixteen open reading frames bounded by eukaryotic promoters, ribosome binding sites, and polyadenylation sites were found, five of which were observed to be transcripted in a developmentally and phenotypically regulated manner. The use of promoters and polyadenylation sites from pRi T.sub.L -DNA to control expression of heterologous foreign structural genes is taught, using as examples the structural genes for Phaseolus vulgaris storage protein (phaseolin), P. vulgaris lectin, a sweet protein (thaumatin), and Bacillus thuringiensis crystal protein. Vectors useful for manipulation of sequences of the structural genes and T-DNA are also provided.
    Type: Grant
    Filed: June 2, 1995
    Date of Patent: October 20, 1998
    Assignee: Mycogen Plant Science, Inc.
    Inventors: Jerry L. Slightom, David A. Tepfer
