Expression of Zzzz\NIaScer\UAS.cHa under the control of any of Scer\GAL4btl.PS, Scer\GAL4G445, Scer\GAL4Act5C.PI or Scer\GAL4αTub84B.PL results in normal and fertile flies.
Co-expression of Zzzz\NIaScer\UAS.cHa under the control of Scer\GAL4btl.PS produces tracheal defects in flies expressing pckT:Zzzz\TEV.CS in a pckG0012 mutant background, phenocopying the pckG0012 mutant phenotype.
