Expression of fz2Scer\UAS.cCa under the control of Scer\GAL4hs.PB using four days of pulsed heat shock treatment consistently produces more follicle cells that accumulate between egg chambers. These extra follicle cells form long stalks with multiple rows of cells instead of one row in the wild type.
Expression of fz2Scer\UAS.cCa under the control of Scer\GAL4da.G32 results in a mild ectopic wg phenotype in the dorsal epidermis of the embryo, consisting of expanded 4o cells at the expense of 3o cells (in wild-type embryos each parasegment contains 4 types of cells in the dorsal epidermis; the 1o, 2o and 3o cells in the anterior half of the parasegment and the 4o cells in the posterior half of the parasegment).
Ubiquitous overexpression of fz2Scer\UAS.cCa under the control of Scer\GAL4e22c does not alter epidermal patterning in a wild-type background.
Animals expressing fz2Scer\UAS.cCa under the control of Scer\GAL4h-1J3 usually die as pupae at 29oC. At lower temperatures, some escapers are seen. These adults have ectopic bristles on the wing blades. Ectopic bristles in the anterior compartment are almost always of the slender or chemosensory type, although an occasional stout bristle is also seen. Ectopic bristles in the posterior compartment are similar to the noninnervated bristles seen at the posterior margin. This "hairy wing" phenotype is also seen in flies expressing fz2Scer\UAS.cCa under the control of Scer\GAL469B or Scer\GAL471B.
