Extended Data Fig. 8: The protein levels of CACG components were not influenced by inhibitors of proteasome or autophagy.

a, Immunoblot analysis shows the effect of the proteasome inhibitor MG132 on the protein levels of CACG components. Twelve-day-old plants grown in solid MS medium were transferred to H2O, liquid MS, or H2O containing 50 µM MG132 for 4 days. The actin protein level is shown as a loading control. b, Immunoblot analysis shows the effect of the autophagy inhibitor 3-MA on the protein levels of CACG components. Twelve-day-old plants grown in solid MS medium were incubated in H2O, liquid MS, or H2O containing 5 mM 3-MA for 4 days. The actin protein level is shown as a loading control. The experiments in (a) and (b) were independently repeated twice and showed similar results.
