Expression of ciScer\UAS.cAa under the control of Scer\GAL4pb.PJ in pb5/+ heterozygotes enhances the reduced pseudotracheal row phenotype of ciScer\UAS.cAa single mutants. When pbScer\UAS.A is overexpressed along with ciScer\UAS.cAa, both under the control of Scer\GAL4pb.PJ, the pseudotracheal row phenotype is suppressed and labial palps appear almost the same as wild type.
When ciScer\UAS.cAa (driven by Scer\GAL469B) is expressed in a wgl-17 background the naked cell fate is induced in the thorax and the most anterior part of the abdomen. Unpigmented denticles are seen in the posterior trunk. However, when ciScer\UAS.cAa is driven by Scer\GAL4αTub84B.PP in a wgl-17 background, naked cuticle is formed in the thorax but denticles are present throughout the abdomen. If ciScer\UAS.cAa is driven by Scer\GAL4wg.PM in a wgl-17 background naked cuticle is produced in a cell autonomous manner. The addition of ciScer\UAS.cAa (driven by Scer\GAL4αTub84B.PP) to arm2 germ-line clones, can suppress denticle belt formation in the thorax of mutant embryos but not in the abdomen. The addition of ciScer\UAS.cAa (driven by Scer\GAL4αTub84B.PP) to tsh8 mutant embryos, can suppress denticle belt formation in the thorax and the abdomen.
Su(hh)IIII or Su(hh)IIIIII rescue the wing vein patterning of animals expressing ciScer\UAS.cAa under the control of Scer\GAL4bs-1348 to almost wild type. Su(hh)IVIV rescues to almost wild type the wing vein patterning in the anterior compartment of the wing of animals expressing ciScer\UAS.cAa under the control of Scer\GAL4bs-1348.
