  • Patent number: 6566137
    Abstract: The invention relates to improved transformation and regeneration of alfalfa, Medicago sativa. Regeneration and transformation of alfalfa is made possible by use of immature cotyledons of alfalfa. By using immature cotyledon tissue, it is possible to regenerate and transform varieties of alfalfa never before capable of regeneration and transformation.
    Type: Grant

  • Patent number: 5324646
    Abstract: The invention relates to improved transformation and regeneration of alfalfa, Medicago sativa.A method is used to transform alfalfa by using particle acceleration. Optimum results with mature cotyledons occurs when bombarding after 24 to 120 hours of imbibing water. Regeneration and transformation of alfalfa is greatly improved by using immature cotyledons or embryos of immature cotyledons for transformation and regeneration. Immature cotyledons include those up to about 25 days past pollination, and preferably include cotyledons excised at 10-15 days past pollination, most preferably including those excised at about 10 days past pollination. These cotyledons have a light green to translucent appearance. Plants resulting from bombardment of somatic embryos of immature cotyledons retain regeneration ability.

  • Patent number: 5322783
    Abstract: Plant cells in tissue culture are more efficiently transformed in a method which involves treatment with a cytokinin followed by incubation for a period sufficient to permit undifferentiated cells in cotyledonary node tissue to differentiate into meristematic cells and to permit the cells to enter the phases between the G1 and division phases of development.
