Expression of pkScer\UAS.cGa under the control of Scer\GAL4ptc-559.1 results in wing hairs pointing towards the midline within the expression domain. Outside of the expression domain wing hair polarity is normal.
Scer\GAL4C-765-driven overexpression of pkScer\UAS.cGa results in variable localised changes in wing hair polarity and occasional cells producing extra hairs. Wing membrane ridge structure shows some deterioration compared to wild-types, but overall ridge orientation is unchanged.
Scer\GAL4Bx-MS1096-driven overexpression of pkScer\UAS.cGa results in disruption of wing hair polarity and ridge formation, but does not produce consistent wing hair or wing membrane ridge reorientation.
Expression of pkScer\UAS.cGa under the control of Scer\GAL4dpp.blk1 in a stripe along the proximo-distal axis of the wing results in a reorientation of wing hairs, which now point towards from the expression domain.
In pkScer\UAS.cGa; Scer\GAL4αTub84B.PL adults, planar polarity in the abdomen is reversed in parts of the anterior compartment of each segment, but is normal in the posterior compartments.
When expression is driven by Scer\GAL4ptc-559.1 hairs point towards the midline in the C region of the wing.
When pkScer\UAS.cGa is expressed as clones in the wing (driven by Scer\GAL4Ubx.PdC) produces a cell non-autonomous phenotype where cells distal to the clones point toward the clone. When pkScer\UAS.cGa is driven by Scer\GAL4ptc-559.1, the wing hairs in the region between wing vein L3 and L4, distal to the anterior crossvein point towards the midline of the wing, unlike wild-type wings, where the wing hairs point distally.
When pkScer\UAS.cGa is driven by Scer\GAL4en-e16E, hairs fail to migrate from the distal vertex of pupal wing cells of these mutants, unlike wild-type. Over expression of pkScer\UAS.cGa when driven by Scer\GAL4da.G32 or Scer\GAL4C-765 gives an extreme tarsal duplication phenotype, including a duplicated socket structure in the proximal T1 segment. Defects are also seen in T2, T3 and T4. Also, when driven by Scer\GAL4da.G32, swirls are seen in the wing hair orientation with different patterns from wing to wing.
