  • Patent number: 6107546
    Abstract: Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for truncated Bacillus thuringiensis Bt2 polypeptide toxins and expression of the chimeric gene in plant cells and their progeny after Integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against Lepidopteron insect pests and in controlling said insect pests.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: August 22, 2000
    Assignee: Aventis CropScience N.V.
    Inventors: Henri Marcel Jozef De Greve, Maria Benita Leonor Fernandez Salgado, Marc Charles Ernest Van Montagu, Mark Albert Vaeck, Marcus Florent Oscar Zabeau, Jan Jozef August Leemans, Hermanus Fransiscus Paulus Hofte
  • Patent number: 5843898
    Abstract: Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for polypeptide toxins produced by Bacillus thuringiensis or having substantial sequence homology to a gene coding for a polypeptide toxin as described herein and expression of the chimeric gene in plant cells and their progeny after integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against certain insect pests and in controlling said insect pests.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: December 1, 1998
    Assignee: Plant Genetic Systems, N.V.
