  • Polypeptides encoded by octopine T-DNA open reading frames
    Patent number: 6111070
    Abstract: The sequence of the T-DNA of the octopine-type Ti plasmid found in Agrobacterium tumefaciens ATCC 15955 is disclosed. Fourteen open reading frames bounded by eukaryotic promoters, ribosome binding sites, and polyadenylation sites were found. The use of promoters and polyadenylation sites from pTi15955 to control expression of foreign structural genes is taught, using as examples the structural genes for the Phaseolus vulgaris storage protein phaseolin, P. vulgaris lectin, thaumatin, and Bacillus thuringiensis crystal protein. Vectors useful for manipulation of sequences of the structural genes and T-DNA are also provided.
    Type: Grant
    Filed: June 2, 1995
    Date of Patent: August 29, 2000
    Assignee: Mycogen Plant Science, Inc.
    Inventors: John D. Kemp, Richard F. Barker

  • Transformed plant which expresses an insecticidally effective amount of a Bowman-Birk tryspin inhibitor from Vigna unguiculata in leaves, stems or roots, and a method for the production thereof
    Patent number: 5306863
    Abstract: The invention relates to a recombinant DNA molecule which comprises a structural gene coding for a trypsin inhibitor, in particular a trypsin inhibitor from a legume, more particularly from Vigna unguiculata (cowpea trypsin inhibitor or CpTI), or for a protein having properties resembling those of CpTI and/or having a substantial degree of homology therewith.The invention also relates to a recombinant DNA plasmid comprising such a DNA molecule, and to the incorporation of the DNA into the nuclear genome of a plant.

  • Plant virus cDNA
    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.
