Fig. 5From: Cold stress induces enhanced chromatin accessibility and bivalent histone modifications H3K4me3 and H3K27me3 of active genes in potatoHeatmap of histone modifications surrounding active genes in RT tubers, cold tubers, and leaves of potato. Genes were sorted based on their expression levels with FPKM greater than 1 in each sample. Genes were divided into 100 bins and aligned together from TSSs to TTSs. Gene flanking regions (± 1 kb) were analyzed in 100 bins. Histone modification level was measured by quantifying the mid-point of pair-end ChIP-seq reads within each bin and normalizing by ChIP-seq read number per bp genome region per million mapped reads.
