Figure S20. Plots of average changes in epigenetic marks over Gst gene family in comparison to genes unaffected in their gene expression states following 28-day PB exposure. Average changes in the log₂ scores (DNA modifications) or fold change in the number of reads (histone modifications) of the marks are plotted against regions outlined earlier in Figure 1. Error bars are standard error and points showing significant deviation from unaffected genes (Willcox test, P-value < 0.005) are denoted by the red asterisk. Red dotted line represents 0 change in epigenetic mark upon PB exposure.
