Key Points

To review the biochemical mechanisms and molecular genetics underlying tryptophan biosynthesis and its subsequent metabolic fates in higher plants.
Literature synthesis of enzymatic assays and molecular cloning studies of plant aromatic amino acid pathways.
Analysis of biochemical phenotypes and mutant plant lines with altered tryptophan synthesis and regulatory control.
Tryptophan synthesis proceeds from chorismate through a multi-step conserved enzymatic pathway regulated tightly by feedback inhibition of anthranilate synthase.
Tryptophan acts as an indispensable precursor for critical plant signaling molecules, including the auxin indole-3-acetic acid and protective indole alkaloids.
