UAS regulatory sequences drive expression of a short inverted repeat.
Expression of GATAeHMS01116 RNAi under the control of Scer\GAL4NP6267 (using tub-Gal80[ts] to limit the time of expression) results in frequent loss of esg-positive cells along with defects in their morphology as well as loss of mitotic intestinal stem cells in the adult posterior midgut.
