Valerie M. Williamson 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).

  • Mi nucleic acids and uses thereof for conferring pest resistance in plants
    Patent number: 6114605
    Abstract: The present invention provide Mi nucleic acids encoding Mi polypeptides which confer resistance to nematodes and other pests. The Mi nucleic acids can be used to produce transgenic plants resistant to these pests.
    Type: Grant
    Filed: October 9, 1997
    Date of Patent: September 5, 2000
    Assignee: The Regents of the University of California
    Inventors: Valerie M. Williamson, Isgouhi Kaloshian, Jafar Yaghoobi, John Bodeau, Stephen B. Milligan
  • Purification of apase-1.sub.1 and retrieval of the nematode resistance gene
    Patent number: 4933286
    Abstract: An isoenzyme from tomato, acid phosphatase-1 isoenzyme (Apase-1.sup.1), has ben purified to homogeneity and is subjected to amino acid sequencing and used to prepare anti-Apase-1 antibodies. The amino acid sequence permits design of probes to recover Apase-1.sup.1 -encoding cDNA; the antibodies are also useful for this purpose. The cDNA is useful to recover the genomic DNA encoding Apase-1.sup.1, which can then be used in walking or jumping techniques to recover the genomic DNA which confers nematode resistance, since this DNA resides immediately adjacent to the Apase-1.sup.1 gene on chromosome 6 of Lycopersicon esculentum.
