  • Production of high tryptophan maize by chloroplast targeted expression of anthranilate synthase
    Patent number: 8981188
    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.

  • High tryptophan maize
    Patent number: 7714189
    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.
