  • Patent number: 6258999
    Abstract: Fertile, stably transformed plants regenerated from culture, produced by one or more bombardments of target cells or tissues with microprojectiles coated with foreign DNA comprising one or more genes coding for a desired trait, and selection of transformed cells in culture, are provided.
    Type: Grant

  • Patent number: 5990387
    Abstract: The invention provides methods for producing a fertile, stably transformed, Zea mays plant. The methods comprise the steps of (a) providing a foreign DNA comprising an expression vector carrying a gene encoding an agronomic trait; (b) providing a maize embryogenic callus, suspension culture, or immature embryo isolated from a plant; (c) introducing the foreign DNA into the embryogenic callus, suspension culture or immature embryo isolated from a plant by one or more microparticle bombardments; and (d) regenerating fertile transgenic Zea mays plant.
    Type: Grant
    Filed: October 6, 1994

    Inventors: Dwight T. Tomes, Arthur Weissinger, John C. Sanford, Theodore M. Klein
  • Patent number: 5886244
    Abstract: Fertile, stably transformed Zea mays plants can be produced by introducing agronomic trait-encoding DNA, via microprojectile bombardment, into maize embryonic callus or suspension culture that has been broken into clumps having a maximum diameter of about 650 microns, where the bombardment is effected within six days of the formation of the clumps.
