METHODS FOR AGROBACTERIUM-MEDIATED TRANSFORMATION

摘要

The present invention relates to methods for improving the transformation frequency of Agrobacterium-mediated transformation of maize embryos. A preferred method for transforming maize using Agrobacterium comprises the steps of: contacting at least one immature embryo from a maize plant with Agrobacterium capable of transferring at least one gene to said embryo; cocultivating the embryos with Agrobacterium; culturing the embryos in medium comprising N6 salts, an antibiotic capable of inhibiting the growth of Agrobacterium, and a selective agent to select for embryos expressing the gene; and regenerating plants expressing the gene.
