Relationship between the gene spacing and sensitivity to MNase treatment. a All intergenic regions were classified into 4 groups based on the distance between the adjacent genes: < 10 kb (black), 10–100 kb (blue), between 100 kb and 1 Mb (apricot), and > 1 Mb (teal). b DNS scores for three groups of intergenic distances shown on scale up to 10 kb (left panel), 100 kb (middle panel), and 300 kb (right panel). c Density plot showing DNS distribution for 1-kb windows for each intergenic distance group. d Distribution of DNS scores for all Gypsy LTRs for the same intergenic distance group, representing a significant effect of intergenic distance on Gypsy LTR DNS score (χ2 = 23,266; p value < 2.2 × 10−16, Kruskal-Wallis test). e Distribution of DNS scores for intergenic segments < 100 kb (gray) and more than 100 kb (white) from neighboring genes for all regions in the genome, distal segments only, and centromeric segments only. Comparisons result in significant differences for all 3 categories (Wall segments = 3023, p value < 2.2 × 10−16; WDistal = 2661, p value 6.7 × 10−12; WCentr. = 2118, p value = 2.9 × 10−4)
