Total protein extraction was performed as previously described (Barco et al., 2019b (link)). Extract [5 µl (DEX : MYB51-myc or DEX : WRKY33-flag) or 50 µl (DEX : MYB51-myc and DEX : WRKY33-flag)] was loaded onto a 10% SDS-PAGE gel, and the separated proteins were transferred to PVDF membrane (Millipore, Billerica, MA), stained with Ponceau S for labeling of total protein, and probed with either FLAG M2 (Sigma-Aldrich, cat# F1804) or c-Myc 9E10 (Santa Cruz Biotechnology, cat# sc-40) antibodies diluted 1:1,000 in 1X PBS containing 5% (w/v) nonfat milk.
