    摘要： A method for increasing efficiency of germplasm screening for transformability may include providing a plurality of lines of plant target tissue to be transformed, characterizing each of the lines to provide characterization data, the characterization data comprises DNA or nucleic acid delivery technique response data and tissue culture response data, eliminating one or more of the plurality of lines based on the characterization data without performing transformation of the plurality of lines, such that a subset of the plurality of lines remains, and performing transformation experiments on the subset of the plurality of lines. The method may also include selecting a DNA or nucleic acid delivery technique protocol and a tissue culture protocol prior to the characterization.

    摘要： The present invention provides methods and compositions which deliver Agrobacterium via microinjection directly into the embryo sac. At the time of injection, the embryo sac can comprise an egg cell, or alternatively, the embryo sac can be fertilized and comprise either a zygote or an embryo. Once inside the embryo sac, the Agrobacterium harboring a T-DNA having a polynucleotide of interest can express of the polynucleotide of interest in the plant. Further, the Agrobacterium can transfer the T-DNA having the polynucleotide of interest to the plant nucleus to produce a transformed plant. The polynucleotide of interest may be stably integrated into the genome of the egg cell, zygote, embryo, or endosperm, and any tissue, plant part, and/or plant generated therefrom.

    摘要： Methods and compositions using a site-specific integration system are combined with methods and compositions which deliver compositions via microinjection directly to the embryo sac of a plant. The methods allow for various components of the site-specific recombination system to be introduced into the cellular environment of the embryo sac a composition comprising at least one component of the site-specific recombination system is injected into an embryo sac, providing improved efficiency of expression, recombination, integration, exchange, excision and/or inversion of a polynucleotide of interest. The polynucleotide of interest may be stably integrated into the genome of the egg cell, zygote, embryo, or endosperm, and tissues, plant parts, and/or plants produced therefrom. Cells, egg cells, zygotes, embryos, endosperm, tissues, seeds, and/or plants produced by the methods and comprising the polynucleotide(s) of interest are also provided.
