RECOMBINANT DNA ENCODING A MONOMERIC ANTRANYLATE SYNTASE, VECTOR, METHODS FOR CHANGING TRYPTOPHAN CONTENT IN A PLANT AND TO PRODUCE A PLANT WITH INCREASED TRYPTOPHAN CONTENT, AND ANIMAL FEED OR HUMAN FOOD

摘要

isolated dna encoding a monomeric anthranilate synthase, vector, seed, transgenic plant cell, methods for altering the tryptophan content in a plant and for producing a plant with increased tryptophan content, and animal feed or human food. The present invention provides a method for conferring tolerance to a tryptophan amino acid analog to a plant and / or altering the tryptophan content of a plant by introducing and expressing an isolated DNA segment encoding an anthranilate synthase in plant cells. Transgenic plants transformed with an isolated DNA segment encoding an anthranilate synthase, as well as human or animal food, seeds and progeny derived from these plants, are also provided.
