Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4elav-C155 results in a mild rough eye phenotype.
P1\creScer\UAS.cHa under the control of Scer\GAL4Mef2.PR results in significantly reduced muscle width, but not length, in third instar larval body wall muscles, as compared to controls.
Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in severe eye abnormalities. Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4en-e16E results in severe truncations of the posterior wing compartment. Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4en-e16E or Scer\GAL4dpp.blk1 results in increased cell death in the wing disc in the region expressing P1\cre. Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4F4 does not result in morphological abnormalities or increased apoptosis in the third larval instar. Expression of P1\creScer\UAS.cHa under the control of Scer\GAL4prd.RG1 does not result in differences in the extent of cell death, proliferation and differentiation between P1\cre-expressing and non-expressing regions. Basal expression of P1\creScer\UAS.cHa (in the absence of a Scer\GAL4 driver) results in mosaic inactivation of wP1\loxP (carried in transgene P{loxP(w+mC)}) due to recombination at the P1\loxP sites flanking the w sequences.
