Additional file 6: Fig. S3. otd expression in 120 hAEL eye imaginal discs. (a) D. mauritiana EAD at 120h. Intensity plots show otd expression intensity measured in the red square area with ImageJ plot intensity tool. (b) D. simulans EAD at 120h. (c) Table and plot showing the area under the curve for each of the discs in which the intensity of otd signal was measured. Black arrowhead: Morphogenetic furrow; oc: ocellar region; dev eye: eye region.
