Additional file 20 of Heterochrony in orthodenticle expression is associated with ommatidial size variation between Drosophila species

Additional file 20: Fig. S11. Schematic showing the position of the 2.5 kb APRE7-8 within the otd locus on the X chromosome of D. melanogaster. A 1.5 kb region shown to drive similar expression to the 2.5 kb region is indicated by a purple bar (37). Below is shown the ATAC-seq profile for this region and the positions of potential fixed mutations specific to D. mauritiana (arrows indicate SNPs and rectangles indicate short indels) with predicted binding sites for Otd, So and Cut in D. melanogaster indicated by arrows. Binding sites indicated with an asterisk contain mutations in D. mauritiana.
