Expression of hhScer\UAS.cPb under the control of Scer\GAL4T155 results in a mirror-symmetric double-posterior pattern (posterior tergite, posterior hairy zone and intersegmental membrane) in the abdominal tergites. The mirror-image patterning or posterior tergite and posterior hairy zone structures caused by expression of hhScer\UAS.cPb under the control of Scer\GAL4T155 is unaffected if the flies are also homozygous for hhts2 (and raised at the restrictive temperature). The transformation of anterior tergite to intersegmental membrane is partly suppressed in these flies.
Scer\GAL4E132-mediated expression in the eye disc leads to massive overgrowth and induction of eye development throughout most of the region anterior to the morphogenetic furrow (MF). No obvious directionality to ommatidial recruitment is seen most likely reflecting the initiation of multiple MFs.
