Patents by Inventor Steven J. Stelman

Steven J. Stelman 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: 6673990
    Abstract: The subject invention provides a DNA construct comprising a promoter operably linked to a nucleic acid encoding an N-terminal core toxin and a C-terminal Cry1Ab protoxin portion, wherein the nucleic acid encoding the C-terminal Cry1Ab protoxin portion is a plant optimized polynucleotide sequence.
    Type: Grant
    Filed: April 5, 2001
    Date of Patent: January 6, 2004
    Assignee: Mycogen Corporation
    Inventors: Guy A. Cardineau, Steven J. Stelman, Kenneth E. Narva
  • Patent number: 6340593
    Abstract: The subject invention provides new, plant-optimized polynucleotide sequences that encode pesticidal toxins. The polynucleotide sequences of the subject invention have certain modifications, compared to wild-type sequences, for example, that make them particularly well-suited for optimized expression in plants. Using the polynucleotide sequences described herein, the transformation of plants can be accomplished, using techniques known to those skilled in the art, in order to confer pest resistance upon the plants. In preferred embodiments, the subject invention provides plant-optimized polynucleotide sequences which encode approximately 15 kDa and approximately 45 kDa pesticidal proteins.

  • Publication number: 20010026940
    Abstract: The subject invention concerns materials and methods useful in the control of pests and, particularly, plant pests. More specifically, the subject invention provides plant-optimized, polynucleotide sequences that encode pesticidal toxins (full-length and truncated). Truncated polynucleotide sequences can be used to produce truncated toxins or for the production of fusion (or chimeric) genes and proteins. The polynucleotide sequences of the subject invention have certain modifications, compared to wild-type sequences, that make them particularly well-suited for optimized expression in plants. Using techniques known to those skilled in the art, the polynucleotide sequences described herein can be used to transform plants in order to confer pest resistance upon said plants. The subject invention further provides plant-optimized, polynucleotide sequences that encode C-terminal, protoxin portions that can be used with genes encoding truncated, core toxins to produce full-length toxins.
