ChIP-quantitative polymerase chain reaction (qPCR) analysis at b1 for H3K27ac, H3K9ac and H3K4me1. a Schematic representation of the b1 locus. Vertical arrows with letters indicate the regions examined by ChIP-qPCR. The b1 hepta-repeat enhancer is indicated with seven black triangles, the b1 coding region by a black box and the TSS by a bent arrow. Grey bars represent TEs and other repetitive sequences. b Enrichment of H3K27ac, H3K9ac and H3K4me1 at the b1 locus relative to the enrichment at the maize actin 1 locus (actin). Error bars represent the standard error of the mean for two (H3K9ac, H3K4me1) or three (H3K27ac) biological replicates
