Abstract

Novel expression vectors and constructs encoding a chloroplast transit peptide (CTP) operably linked to a monomeric anthranilate synthase are provided. Additionally, novel polynucleotide sequences encoding monomeric anthranilate synthases are provided. Also provided are methods for increasing the levels of free tryptophan in transgenic plants containing the expression vectors and constructs.
