Transformation systems: Registered corn products were transformed using protoplast electroporation to introduce the desired DNA or methods employing bombardment of particles

Product characterization is critical to understanding the way in which the registered products were made and the unique characteristics that need to be assessed for each Bt plant-incorporated protectant. The product characterization data provide information on the specific transformation systems used for each product, on the actual DNA inserted into the plant, on the inheritance and stability of these traits in the plant, on biochemical characteristics of the Bt protein and on Bt protein expression levels for various plant tissues. Specific information and data for each of the registrations seeking renewal are included in tabular and descriptive formats.
