UAS regulatory sequences drive expression of Hsap\PKNOX1.
eye, with Scer\GAL4dpp.blk1
leg | distal, with Scer\GAL4dpp.blk1
leg | distal | ectopic, with Scer\GAL4dpp.blk1
Induction of Hsap\PKNOX1Scer\UAS.cJa driven by Scer\GAL4dpp.blk1 at 25oC causes a mild reduction in eye size, the distal leg segments are missing or fused, occasionally with a short bifurcation. The eyes and antennae are normal. At 29oC a stronger phenotype is seen, eyes are reduced and the aristae are often missing.
