Zpr131ZZ mutants exhibit a complete failure to generate gas-filled lumens. Zpr131ZZ mutant cells also show a significant branching defect. Zpr131ZZ mutants are able to generate a central branch and secondary branches, but fail to undergo tertiary and quaternary branching. While the branching phenotype is highly variable, gas-filling is completely abrogated in all Zpr131ZZ mutant terminal cells.
Zpr131ZZ has embryonic/larval tracheal section | somatic clone phenotype, non-enhanceable by Egfr2.UAS/Scer\GAL4btl.PS

Overexpression of Egfr2.Scer\UAS or Egfr2.A887T.Scer\UAS in Zpr131ZZ mutant MARCM tracheal cell clones does not alter the Zpr131ZZ gas-filling defect.
MARCM mosaics of Zpr131ZZ cells that overexpress btlScer\UAS.T:λ\cI-DD under the control of Scer\GAL4btl.PS display a Zpr131ZZ-like phenotype.
Zpr131ZZ is rescued by Zpr1UAS.cRa/Scer\GAL4btl.PS
