Scer\GAL4en.PU>meltScer\UAS.cTa adult wings are slightly larger than control wings expressing only the driver.
Strong overexpression meltScer\UAS.cTa in the developing and adult eye does not noticeably affect eye size or morphology.
The total number of photoreceptors, as well as the number of Rh5-positive and Rh6-positive photoreceptors is normal in the eyes of larvae expressing meltScer\UAS.cTa under the control of Scer\GAL4so-7.GAL4.
Expression of meltScer\UAS.cTa in all photoreceptors, driven by Scer\GAL4GMR.long, causes R8 photoreceptors to adopt a p fate. The dorsal rim area R8 cells are not affected. Expression of meltScer\UAS.cTa, under the control of Scer\GAL4Rh5.PT and Scer\GAL4Rh6.PD in R8 photoreceptor cells, increases the number of cells that adopt an R8 fate and causes ~63% of cells to express both Rh5 and Rh6, which are indicative of both p and y fates. Expression of this transgene in R7 photoreceptor cells, driven by Scer\GAL4Rh3.PP and Scer\GAL4Rh4.PT, does not affect the fate specification of R8 cells.
