Differential DNA methylation associated with photoperiod in Nasonia. (A) The methylation is shown across the five chromosomes and the unplaced (U) scaffolds. From the outer to inner circle, the data tracks are short-day methylated CpGs (red), long-day methylated CpGs (blue), methylation difference (red/blue), and significantly differentially methylated sites (q < 0.05, dark gray). The lack of differential methylation in the U scaffolds is probably because they encompass substantially fewer genes. (B) Differential methylation in the heix (LOC100118618) gene. Of 42 CpG sites that were covered, six (*) were significantly more methylated in short day (q < 0.05). (C) Differential methylation in msn indicates increased methylation in long day: There are seven covered CpG sites on this gene, of which five (*) are methylated at q < 0.01.
