Patent number: 7547820Abstract: The invention provides genetically engineered, preselected DNA sequences and methods of using them to alter the nutritional content of plant seed. Methods of the invention are directed to increasing the weight percent of at least one amino acid essential to the diet of animals, or increasing the starch content, of a plant. One such method involves stably transforming a cell of a plant with an a preselected DNA sequence encoding an RNA molecule substantially identical or complementary to a messenger RNA (mRNA) encoding a plant seed storage protein, preferably a seed storage protein which is deficient in at least one amino acid essential to the diet of animals. An alternative method employs stably transforming cells with at least two preselected DNA sequences, one of which encodes an RNA molecule substantially identical or complementary to a messenger RNA (mRNA) encoding a plant seed storage protein, and the other preselected DNA molecule which encodes a preselected polypeptide.Type: GrantFiled: November 1, 2005Date of Patent: June 16, 2009Assignee: Dekalb Genetics CorporationInventors: Julie A. Kirihara, Kenneth A. Hibberd, Janice Anthony

Patent number: 6222100Abstract: This invention is directed to the production of plants, plant tissues and seeds which are resistant to inhibition by an herbicide which normally inhibits the growth and development of those plants, plant tissues and plant seeds. In particular this invention is directed to altered acetohydroxyacid synthase enzymes which are resistant to inhibition by herbicides which normally inhibit the activity of the synthase before such alteration. This invention further relates to genes encoding such enzymes, and to processes for utilizing these novel genes and enzymes. Further products of the invention include plants, plant tissues and seeds which exhibit resistance to such herbicides resulting from expression of genes encoding herbicide resistant acetohydroxyacid synthase enzyme.Type: GrantFiled: June 5, 1995Date of Patent: April 24, 2001Assignee: MGI Pharma, Inc.Inventors: Paul Curtis Anderson, Kenneth A. Hibberd
