UASt regulatory sequences drive expression of an inverted repeat.
The few escapers from the expression of Megf8GD2634 under the control of Scer\GAL4Act5C.PI show small body size, narrow abdominal segments, and planar polarity defects, as shown by the defective number and orientation of abdominal sensory bristles, as compared to controls.
Adults expressing CG7466GD2634 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.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 0% or 0-10% of the Scer\GAL4pnr-MD237-expressing area of the notum, depending on the insertion line used.
