    摘要: Coated meristematic tissue comprising a dry or dryable meristematic tissue (1) and solid support (3) in contact with said tissue and partially covering it, in such a manner that the tissue remains in contact with a volume of air (2). The support is capable of absorbing a nutrient medium and germinating. The invention is suitable for seeding or culturing purposes.

    摘要: Whole scutella are isolated from immature zygotic embryos of cereal plants and cultured, in the absence of the zygotic embryo axis, to produce somatic embryos, which in turn are converted into plantlets. The scutellar cells optionally are transformed with foreign DNA so that at least some of the resulting plantlets are transgenic. The regeneration is much more efficient and rapid than with conventional methods.

    摘要: 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.
