A Simplified Seed Transformation Method for Obtaining Transgenic Brassica napus Plants

We report here a seed transformation of sonication-assisted, no-tissue culture to rapidly produce transgenic Brassica napus plants. This method comprises the steps of treating seeds by ultrasonic wave, inoculating Agrobacterium tumefaciens with a recombinant ChIFN-α gene and germinating directly of treatment seed on wet filter papers. The obtained transformants were verified by GUS histochemical assay and nested PCR amplification. It suggests that seed transformation has a potential use in genetic transformation of rape.
