Conversion of Exogenous IAA to OxIAA in the Arabidopsis Root Apex.
Wild-type Arabidopsis Col-0 seedlings were treated at 8 DAG with and without 10 μM IAA for 5.5 h, and the concentration of oxIAA in the root apex (pooled 5-mm sections of the root tip) was analyzed by LC-MS/MS. Error bars represent sd (n = 5).
