The Role of piRNA-Mediated Epigenetic Silencing in the Population Dynamics of Transposable Elements in Drosophila melanogaster
Fig 4
Comparisons of the H3K9me3 density for genes whose nearest TEs have different population frequencies.
TEs that are observed in the North American D. melanogaster population (Observed) have higher population frequencies than those that are not observed in the population (NOT). Genes whose nearest TEs are observed in the population have significantly lower H3K9me3 density. Dashed lines show the median of H3K9me3 density for genes whose nearest TE are not observed in the population. Numbers of genes included in the analysis are 297 (for Observed) and 491 (for NOT). Notations for p-values are * (p < 0.05), ** (p < 0.01), and *** (p < 0.001).
