UASt regulatory sequences drive expression of an inverted repeat.
Adults expressing FoxKGD4313 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.
Embryos lacking fd68A function, through the presence of fd68AGD4313 (expressed under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16), are morphologically deformed. Most embryos stop developing around stage 13, after germ band retraction, and show dramatic alteration of the segmental expression of en.
Elimination of fd68A in the endoderm by expression of fd68AGD4313 under the control of Scer\GAL448Y results in incomplete midgut development.
