  • Transgenic plants expressing DNA constructs containing a plurality of genes to impart virus resistance
    Publication number: 20020059660
    Abstract: The present invention provides a chimeric recombinant DNA molecule comprising: a plurality of DNA sequences, each of which comprises a plant-functional promoter linked to a coding region, which encodes a virus-associated coat protein, wherein said DNA sequences are preferably linked in-tandem so that they are expressed in virus-susceptible plant cells transformed with said recombinant DNA molecule to impart resistance to said viruses; as well as methods for transforming plants with the chimeric constructs and for selecting plants which express at least one of said DNA sequences imparting viral resistance.
    Type: Application
    Filed: October 9, 2001
    Publication date: May 16, 2002
    Inventors: David M. Tricoli, Kim J. Carney, Paul F. Russell, Hector D. Quemada, J. Russell McMaster, John F. Reynolds, Rosaline Z. Deng

  • Potyvirus coat protein genes and plants transformed therewith
    Patent number: 5998699
    Abstract: The present invention relates to the coat protein genes of Papaya Ringspot Virus Strain papaya ringspot (PRV-p), Watermelon Mosaic Virus II (WMVII), and Zucchini Yellow Mosaic Virus (ZYMV); to expression vectors which contain a coat protein gene for PVP-p, WMVII or ZYMV, and, additionally, the necessary genetic regulatory sequences needed for expression of a gene transferred into a plant; to bacterial or plant cells which are transformed with an expression vector containing the PVP-p, WMVII or ZYMV coat protein genes; to transgenic plants which are produced from plant cells transformed with an expression vector containing the coat protein gene from PVP-p, WMVII or ZYMV; and to a process of producing transgenic plants which have increased resistance to viral infection.
