Fig. 4From: An integrative analysis of post-translational histone modifications in the marine diatom Phaeodactylum tricornutum Clustering analysis of H3K27me3 over genes and correlation with gene expression. a H3K27me3 enrichment is shown in red while absence is represented in gray. Gene expression levels are shown as a heat map with red reflecting high (expression level FPKM [fragments per kilobase of exons per million reads mapped] greater than 20) and green representing low expression (expression level FPKM between 0 and 20). b Expression boxplots for each H3K27me3 enrichment cluster. Un refers to genes unmarked by H3K27me3Back to article page
