Abstract: The invention relates generally to phosphopantetheinyl transferases that are required for activation of a polyketide synthase complex to synthesize long chain poly-unsaturated fatty acids (LC-PUFA's) such as docosahexaenoic acid and eicosapentaenoic acid. In particular, the invention relates to bacterial phosphopantetheinyl transferases, DNA constructs for their expression in host cells, and seed, oil and meal when the host cells comprise a plant. Also provided is a method for making a plant oil containing docosahexaenoic acid and/or eicosapentaenoic acid.

Abstract: The present invention provides a method for altering the tryptophan content of a plant by introducing and expressing an artificial polynucleotide sequence encoding an anthranilate synthase in the cells of the plant. Transgenic plants transformed with an artificial polynucleotide sequence encoding an anthranilate synthase, as well as human or animal food, seeds, and progeny derived from these plants, are also provided.

Abstract: The present invention generally relates to the field of plant genetics and protein biochemistry. More specifically, the present invention relates to modified proteins having an increased number of essential amino acids. The invention provides proteins modified to have an increased number of essential amino acids, nucleic acid sequences encoding the enhanced proteins, and methods of designing, producing, and using the same. The invention also includes compositions, transformed host cells, transgenic plants and seeds containing the enhanced proteins, and methods for preparing and using the same.
