UASt regulatory sequences drive expression of an inverted repeat.
lethal - all die before end of P-stage, with Scer\GAL4Act5C.PU
some die during pharate adult stage, with Scer\GAL4Act5C.PU
scutellum, with Scer\GAL4pnr-MD237
Expression using Scer\GAL4pnr-MD237 results in defects in notum scutellar morphologies.
