The small wing induced by overexpression of Dp110^KD can be dominantly enhanced or suppressed. (A–D, F, and G) Female wings are shown. (A) Wild type. (B) MS1096>Dp110^KD/+. (C and D) Tor mutations dominantly enhance the small-wing phenotype. (E) Several X chromosome deletions dominantly modify the MS1096>Dp110^KD small-wing phenotype. Schematic of the X chromosome shows the individual deficiencies tested. Rectangles indicate the regions deleted in each deficiency strain with lines indicating uncertain break points. Vertical dashed lines group together (conservatively) chromosomal regions that, when deleted, either enhance (solid-bar deficiencies; E) or suppress (shaded-bar deficiency; S) the phenotype. The deficiencies corresponding to these regions are listed in materials and methods. (F) An example of a deficiency that dominantly enhances the small-wing phenotype. (G) Df(1)BA1 dominantly suppresses the small-wing phenotype.
