Rough eye phenotype and identification of enhancers and suppressors of <i>UAS::Parvin-GFP, longGMRGal4</i>.

<p>Adult eye confocal optical projections from the <i>longGMRGal4</i> stock served as control (A), the starting <i>UAS::Parvin-GFP, longGMRGal4</i> genotype (B) and the recovered modifiers (C–L). The main suppressors of the modifier screen show morphology of the ommatidia that is reminiscent of the control: <i>UAS:Wech</i> (C), <i>UAS:PTEN</i> (E), <i>Df(3L)Exel6119</i> (G), <i>Df(3L)ED2</i> (I), and <i>UAS:IRXrp1</i> (K). The main enhancers of the screen are <i>Df(3R)e-GC3</i> (D), <i>UAS:IREip93F</i> (F), <i>UAS:IRmys</i> (H), <i>UAS:IRzasp52</i> (J), and <i>UAS:IRChd64</i> (L).
