Under control conditions, the adulthood-only expression of SxlUAS.cRa under the control of Scer\GAL4esg-NP7397 (and Gal80[ts], for the temporal regulation of expression) does not significantly affect the number of progenitor cells (intestinal stem cells/enteroblasts) or the mitotic index in the female or male adult posterior midgut, as compared to controls.
Expression of SxlScer\UAS.cRa under the control of Scer\GAL4arm.PS results in full male lethality. Female viability is unaffected.
Expression of SxlScer\UAS.cRa in a Sxlf1 mutant background results in full male lethality. Female viability is unaffected.
