Patent ID: 8742204

Claim:
A transgenic plant comprising a nucleic acid encoding a fusion protein wherein the fusion protein comprises: (a) a first polypeptide segment comprising a first bacterial periplasmic binding protein (bPBP); and (b) a second polypeptide segment comprising a second bPBP, and (c) optionally a transit peptide, wherein the N terminus of the second polypeptide segment is linked to the C terminus of the first polypeptide segment, wherein the C terminus of the optional transit peptide is linked to the N terminus of the first polypeptide segment, wherein the second polypeptide segment is the C terminus of the fusion protein, wherein the optional transit peptide or the first polypeptide segment is the N terminus of the fusion protein, and wherein each bPBP binds to a specific ligand and controls the availability of the ligand to a cell, and wherein the transgenic plant comprising the fusion protein has an altered metabolism relative to a corresponding control plant that does not comprise the fusion protein.
