(G - I) Boxplots showing FC (log2) in gene expression between indicated samples for 3 groups of genes classified according to H3K27me3 enrichments (as shown in E). Lower hinge, central line and upper hinge represent 25th, 50th (median) and 75th percentiles respectively. Upper/lower whiskers extend to the largest/smallest values no further than 1.5 * IQR from the upper/lower hinge, where IQR is inter-quartile range or distance between 25th and 75th percentiles. Outliers are not displayed. The notches extend $1.5*IQR/\sqrt{n}$ where n is a number of genes in each H3K27me3 class. Number of genes (n) in "Low", "Medium" and "High" H3K27me3 class used for boxplots are 9824, 2311, 2647 respectively. Expression changes were estimated using 2 or 3 biological replicates for each condition. Statistical significance was estimated using two-sided t-tests.
