  • DNA constructs and methods to enhance the production of commercially viable transgenic plants
    Patent number: 7575917
    Abstract: The present invention has incorporated a non-lethal negative selectable marker gene into the vector backbone DNA of a DNA plasmid used to transform plant cells. These transgenes are designed to express a non-lethal gene product in plant cells that contain the vector backbone DNA of the DNA plasmid. The gene products of the non-lethal negative selectable marker gene are involved in plant hormone biosynthesis pathways, plant hormone substrate diversion, plant hormone degradation, plant hormone signaling or metabolic interference. The use of these DNA plasmids to transform plant cells provides for the enhanced production of commercially viable plants.
    Type: Grant
    Filed: April 8, 2004
    Date of Patent: August 18, 2009
    Assignee: Monsanto Technology LLC
    Inventors: Larry A. Gilbertson, Elysia K. Krieger, Wanggen Zhang, Xudong Ye
  • METHODS FOR PRODUCING TRANSGENIC PLANTS
    Publication number: 20080118981
    Abstract: A method of producing a stably transformed corn plant in a single container is demonstrated. This method allows for the automation of the transformation process and reduces labor, material, and ergonomic costs associated with traditional plant tissue culture systems.

  • Novel Method for Agrobacterium Preparation for Plant Transformation
    Publication number: 20030196219
    Abstract: The present invention relates to a novel method of preparing Agrobacterium for plant transformation. In particular, the invention relates to storing the Agrobacterium in the cold for some period of time. Surprisingly, this increases transformation efficiency.
