Enrichment of H3K27me3 within Genes and Effects of Paf1C Disruption.

(A) Mean genic positional enrichment for H3K27me3 for protein-coding genes or transposon-related/pseudogenes. (B) H3K27me3 enrichment for genes within ten-percentile expression level bins as described for Figure 1B. (C) Mean genic positional enrichment for genes within twenty-percentile bins according to length of transcribed region. (D) Enrichment for H3K27me3 for genes within specific expression level and expression entropy bins as described for Figure 2D. (E) Mean enrichment across the transcriptional unit (left panel) for the ∼18,000-gene set, or across the 5′ end/TSS (center) or 3′ end (right) of genes with transcribed regions >2 kb in length, for wild-type plants (WT) or vip3 mutants. (F) Enrichment for transposon-related genes and pseudogenes. (G) Paf1C-dependent H3K27me3 enrichment with respect to expression level, as determined for Figure 1E. (H) Paf1C-dependent enrichment for H3K27me3 with respect to gene length, as determined for Figure 1E.
