UASt regulatory sequences drive expression of an inverted repeat.
decreased cell number | female | third instar larval stage, with Scer\GAL4C587
lethal, with Scer\GAL4pnr-MD237
terminal filament cell | decreased number | third instar larval stage, with Scer\GAL4C587
Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage.
