When indole-3-acetic acid (IAA) is applied to the cotyledons of broad bean seedlings ( Vicia faba L. cv Chukyo), the major metabolites found in the roots are 3-(O-β-glucosyl)-2-indolone-3-acetylaspartic acid (Glc-DIA-Asp) and 3-hydroxy-2-indolone-3-acetylaspartic acid (DIA-Asp). In this report, the metabolic pathway from IAA to the two dioxindole-3-acetic acid (DIA) conjugates was investigated by using [^<14>C] IAA, [^<14>C]DIA, [<14>C]indole-3-acetylaspartic acid (IAA-Asp), and [^<14>C]IAA-[^3H]Asp. The precursor of DIA-Asp was found to be IAA-Asp but not DIA. Incorporation of the double labeled IAA-Asp into the DIA conjugates demonstrated that hydrolysis of IAA-Asp was not involved in the formation of the DIA conjugates. DIA-Asp was further metabolized to Glc-DIA-Asp in the cotyledons, while formation of Glc-DIA-Asp in the roots was very low. Glc-DIA-Asp formed in the cotyledons was transported to the roots.
