1. A nucleic acid composition, comprising:
a first polynucleotide encoding a first synthase, wherein the first synthase comprises an indole-3 acetic acid hydrolase capable of catalyzing the synthesis of an orthogonal signal from a first precursor molecule;
a second polynucleotide encoding a second synthase, wherein the second synthase is capable of catalyzing the synthesis of the first precursor molecule from a second precursor molecule; and
a third polynucleotide encoding a transporter capable of transporting the orthogonal signal across a cell membrane;
wherein the first polynucleotide, the second polynucleotide, and the third polynucleotide are operably linked to a ubiquitous mammalian promoter.
