Amy O. Charkowski 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).

  • DNA molecules and polypeptides of Hrp pathogenicity island and their uses
    Patent number: 7102059
    Abstract: One aspect of the present invention relates to isolated nucleic acid molecules (i) encoding proteins or polypeptides of Pseudomonas CEL and EEL genomic regions, (ii) nucleic acid molecules which hybridize thereto under stringent conditions, or (iii) nucleic acid molecules that include a nucleotide sequence which is complementary to the nucleic acid molecules of (i) and (ii). Expression vectors, host cells, and transgenic plants which include the DNA molecules of the present invention are also disclosed. Another aspect relates to the isolated proteins or polypeptides and compositions containing the same. The nucleic acid molecules and proteins of the present invention can be used to imparting disease resistance to a plant, making a plant hypersusceptible to colonization by nonpathogenic bacteria, causing eukaryotic cell death, and treating cancerous conditions.
