L. Sue Loesch-Fries 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: 5736627
    Abstract: The making of plant cells which contain coat protein of a target plant virus is disclosed. Construction of coat protein genes and transformation of coat protein genes into plant cells is also taught. Such cells are relatively resistant to infection by the target virus when compared with cells not containing coat protein. Furthermore, methods and DNA molecules useful for producing plant cells containing coat protein are also disclosed.
    Type: Grant
    Filed: March 29, 1988
    Date of Patent: April 7, 1998
    Assignee: Pioneer Hi-Bred International, Inc.
    Inventors: L. Sue Loesch-Fries, Nancy P. Jarvis, Donald J. Merlo
  • Patent number: 5316930
    Abstract: The making of plant cells which contain antisense RNA (aRNA) complementary to the mRNA of an alfalfa mosaic virus is disclosed. Construction of such aRNA genes and transformation thereof into plant cells is also taught. Such cells are relatively resistant to infection by the target virus when compared with cells not containing the aRNA. Methods and DNA molecules useful for producing plant cells containing said aRNA are also disclosed.
    Type: Grant
    Filed: January 5, 1989
    Date of Patent: May 31, 1994

  • Patent number: 4921802
    Abstract: A method is disclosed for detecting RNA viral infections in plants comprising the isolation of an RNA molecule, e.g., from alfalfa mosaic virus (AMV), production of full-length cDNA transcripts, cloning into plasmids and propgation of the recombinant plasmid. This recombinant DNA plasmid is utilized diagostically to test a plant for infection by a virus, e.g., AMV.
