Expression of JIL-1CTD.Scer\UAS.T:Avic\GFP-ECFP under the control of Scer\GAL4da.G32 enhances position effect variegation in In(1)wm4 flies, as indicated by the increased proportion of red ommatidia and a 343% increase in the optical density of eye pigment levels, when compared to controls.
Expression of JIL-1CTD.Scer\UAS.T:Avic\GFP-ECFP in a JIL-1z2; w118E-10/+ mutant background, under the control of Scer\GAL4da.G32, enhances the position effect variegation seen in the eye, as indicated by a decrease in the proportion of red ommatidia and a statistically significant 54% decrease in optical density of eye pigment levels.
