Scer\GAL4444-mediated expression at 17oC causes the thoracic and some head segments of first instar larvae to display A1 identity. At 29oC larvae develop all segments anterior to A2 with an A3-A5 pattern.
When expressed via Scer\GAL41151, T2 myoblast migration during pupal development is unaffected. The indirect flight muscle fail to complete development and eventually degenerate.
When expressed via Scer\GAL4how-24B in embryos, an ectopic precursor for abdominal muscle 26 appears in the ventral region of T1-T3. Ventral longitudinal muscles of thoracic segments assume the identity of the abdominal segments. Abdominal segment 1 gains two muscles that it normally lacks: external ventral oblique muscles 17 and 25. Insertion sites of transformed muscles are sometimes aberrant. The thoracic cuticle remains unaffected. Both gastric caeca and the first midgut constriction are missing.
