Abstract: The present invention provides DNA constructs comprising exogenous polynucleotides encoding a threonine deaminase and/or AHAS. Transgenic plants transformed with the constructs, as well as seed and progeny dervied from these plants, are also provided. The transgenic plants have an increased level of one or more amino acids as compared to a non-transgenic plant of the same species.

Abstract: Nucleic acid sequences, vectors, recombinant host cells, transgenic plants, and methods for their preparation are disclosed. The nucleic acid sequences encode threonine deaminase proteins that catalyze the conversion of threonine to ?-ketobutyrate. One or both of the amino acids at positions 447 and 481 of the encoded proteins can be selected from groups of particular amino acids. For example, the amino acid at position 447 can be alanine, isoleucine, valine, phenylalanine, tryptophan, or methionine. The amino acid at position 481 can be alanine, isoleucine, proline, phenylalanine, tryptophan, or methionine.
