James F. Wong 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).

  • Arthropod defensins
    Publication number: 20020069427
    Abstract: This invention relates to an isolated nucleic acid fragment encoding a defensin. The invention also relates to the construction of a chimeric gene encoding all or a portion of the defensin, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the defensin in a transformed host cell.
    Type: Application

    Inventors: James K. Presnail, Zude Weng, James F. Wong
  • External regulation of gene expression
    Patent number: 5608143
    Abstract: The preparation and use of nucleic acid promoter fragments derived from several genes from corn, petunia and tobacco which are highly responsive to a number of substituted benzenesulfonamides and related compounds are described. These promoter fragments are useful in creating recombinant DNA constructions comprising nucleic acid sequences encoding any desired gene product operably linked to such promoter fragments which can be utilized to transform plants and bring the expression of the gene product under external chemical control in various tissues of monocotyledonous and dicotyledonous plants.
    Type: Grant
    Filed: July 25, 1994
    Date of Patent: March 4, 1997
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Howard P. Hershey, Carol D. Katayama, Edward J. Ralston, Timothy D. Stoner, James F. Wong
