A new indole-3-acetic acid (IAA) metabolite in the root of Vicia faba L. cv. Chukyo was identified as 3-hydroxy-2-indolone-3-acetylaspartic acid, with the simpler name of dioxindole-3-acetylaspartic acid, by comparison with the authentic sample. Formation of dioxindole-3-acetic acid conjugates seems to be a major route of IAA metabolism in Vicia roots.
