a A wild-type callus was treated with DMSO or 40 mmol NAA. Callus extracts were treated with the MdIAA121-His fusion protein and then incubated for the indicated periods. Actin was used as a loading control. b MG132 inhibited the degradation of MdIAA121. A wild-type apple callus extract was treated with DMSO or 100 mM MG132 for 0.5 h and then incubated with MdIAA121-His for the indicated periods
