Characterization of binding sites of HSFA2/HSFA3 according to their distance from associated genes, chromatin profiles, and chromatin states. a Density plot illustrating global distance of peaks from the nearest transcriptional start site (TSS). Gray line indicates distance of 2000 bp. b Density plot illustrating global distance of peaks from the nearest transcriptional start site (TSS) in ChIP-seq clusters. c Number of peaks and number of associated genes in cclusters. d Enrichment of histone modifications in seedlings grown under control (NHS) conditions in a window of 3 kb around the peak centers. Ccluster c11, c12, and c14 are enriched for H3K4me3 at the flanks of the peaks, cluster c13 is enriched for H3K9me2, and cluster c15 is enriched for H3K27me3. Histone modification data were reanalyzed from [42]. e ChIP-seq peaks are enriched in different chromatin states, with clusters c7, c11, c12, and c14 being enriched in chromatin states 1 and/or 2. The proportion of peaks in cclusters that are associated with the indicated chromatin states is depicted. *p < 0.05 Fisher’s exact test. Chromatin states are taken from [43]
