Tryptophan-dependent pathway for IAA biosynthesis in bacteria. IAM: indole-3-acetamide; IPyA: indole-3-pyruvic acid; IAAld: indole-3-acetaldehyde; TAM: tryptamine; IAN: indole-3-acetonitrile; ILA: indole-3-lactic acid; TOL: indole-3-ethanol. Red lines: the IAA biosynthesis pathways in ZZ21 detected by genome-wide analysis; green lines: the IAA biosynthesis pathways in ZZ21 detected by metabolomic analysis; purple lines: the IAA biosynthesis pathways in ZZ21 identified by HPLC-MS.
