  • Publication number: 20100154083
    Abstract: Compositions and methods are provided to screen, identify, select, isolate, and/or regenerate targeted integration events using seed priming. Seed priming provides the identification of a seed having stably incorporated into its genome a site-specific recombinase mediated integration of a selectable marker at a target locus operably linked to a promoter active in the seed.

  • Publication number: 20030135889
    Abstract: The invention provides improved transformation methods. In particular the method provides increased transformation frequency, especially in recalcitrant plants. The method comprises stably transforming a target cell with at least one polynucleotide of interest. The target cell has been previously transformed to stimulate growth of the cell and has gone through at least one cell division.

  • Patent number: 6512165
    Abstract: The invention provides improved plant transformation methods. In particular the method provides increased transformation freequency, especially in recalcitrant plants. The method comprises stably transforming a target cell with at least one polynucleotide of interest. The target cell has been previously transformed to stimulate growth of the cell and has gone through at least one cell division.

  • Patent number: 6444470
    Abstract: The invention relates to compositions and methods and for genetically transforming Zea mays plants. Compositions comprising transformation-enhancing agents and methods of use are provided. The methods involve administering an effective amount of a transformation-enhancing agent to a Zea mays plant. The compositions and methods of the invention find use in improving transformation efficiency and increasing the embryogenic response of callus.

  • Patent number: 5736369
    Abstract: To obtain a transgenic cereal plant which is stably transformed, an exposed cereal meristem is subjected to biolistic bombardment in order to target non-differentiated meristem cells for transformation. Immature embryos at the early proembryo, mid proembryo, late proembryo, transitional or early coleoptilar stage are harvested for biolistic bombardment. The meristem tissue or cells fated to contribute to the meristem then are manipulated in order to enlarge transgenic sectors, either through selection and/or through effecting a proliferation from the tissue of shoots or multiple meristems per se. The shoot population thus obtained then is screened, by means of a nonlethal enrichment assay, to identify either chimeric sectors that will contribute to germline transmission, or non-sectored, L2 periclinal chimeras that will by definition transmit to progeny.
