a, Experimental design to test whether polycomb redistribution requires transcription. b, qRT-PCR depicting fold change by ΔΔCt method with indicated treatments from n = 3 biological replicates. c,d, Scatterplot showing that Ring1b and Suz12 changes following Brg1 degradation are highly correlated despite global inhibition of transcription for all peaks c, and peaks that were significantly changed by Brg1 degradation alone (d) (FDR < 0.1). e, Scatterplot of changes to Ring1b and Suz12 upon treatment with auxin (auxin/control) or triptolide (triptolide/control) showing distinct effects from the two treatments. Correlation and p-values were obtained from Pearson’s product moment correlation for c-e, from n = 4 biological replicates at the 8 h timepoint.
