UASt regulatory sequences drive expression of an inverted repeat.
lethal, with Scer\GAL4pnr-MD237
lethal | pupal stage, with Scer\GAL4pnr-MD237
lethal - all die before end of pupal stage, with Scer\GAL4Bx-MS1096
some die during pupal stage, with Scer\GAL4Bx-MS1096
Expression under the control of Scer\GAL4pnr-MD237 results in lethality (either before or at the pupal stage), depending on the insertion line used.
