Expression of JIL-1ΔCTD.Scer\UAS.T:Avic\GFP-ECFP under the control of Scer\GAL4da.G32 suppresses position effect variegation in In(1)wm4 flies, as indicated by the increased proportion of red ommatidia and a 348% increase in the optical density of eye pigment levels, when compared to controls.
Expression of JIL-1ΔCTD.Scer\UAS.T:Avic\GFP-ECFP in a JIL-1z2; w118E-10/+ mutant background, under the control of Scer\GAL4da.G32, suppresses the position effect variegation seen in the eye, as indicated by an increases in the proportion of red ommatidia and a statistically significant 151% increase in the optical density of eye pigment levels.
