Patents by Inventor Yiji Xia

Yiji Xia 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).

  • Regulation of anthocyanin pigment production
    Patent number: 6573432
    Abstract: A method for determining gene expression in transgenic plants is disclosed. This method includes providing expression vectors having the PAP1 or PAP2 gene linked to an expressed gene of interest. If the expression vector is activated, the PAP1 or PAP2 genes confer a purple pigmentation to the transgenic plant. Thus, plants that have been successfully transformed are easily identifiable by visual inspection.

    Inventors: Justin Borevitz, Yiji Xia, Richard A. Dixon, Christopher J. Lamb
  • Constitutive disease resistance (CDR1) gene and methods of use thereof
    Publication number: 20020108145
    Abstract: Substantially purified CDR1 polypeptide, isolated polynucleotides encoding CDR1 polypeptide, vectors containing CDR1, host cells expressing CDR1, and antibodies which bind to CDR1 are all provided. The invention also provides a method of producing a genetically modified plant characterized as having increased disease resistance as compared to wild-type plants. A method is also provided for identifying novel disease resistance genes by probing a nucleic acid library with at least a fragment of a polynucleotide encoding CDR1, and selecting those clones that hybridize with the fragment.

  • Isolation and use of cuticular lipid genes
    Patent number: 6060644
    Abstract: The present invention relates to cuticular lipid genes, their gene products, and methods of use thereof, for the generation of new plant varieties having novel environmental, disease and pest resistance. In particular, certain isolated or enriched nucleic acids specifying cuticular lipid genes, or portions thereof, are disclosed.
