Auxin inactivation plays important roles in plant development. Here the authors show that the main route of IAA inactivation in Arabidopsis is via conjugation by GH3 IAA-amidosynthetases followed by DAO1 dioxygenase-mediated oxidation of the conjugated forms and hydrolysis by ILR1 to release inactive oxIAA.
