UAS regulatory sequences drive expression of a short inverted repeat.
embryonic/larval tracheal section, with Scer\GAL4btl.PS
tracheal lumen, with Scer\GAL4btl.PS
Downregulation of Egfr in the tracheal system through expression of EgfrJF02384 under the control of Scer\GAL4btl.PS results in strong gas-filling defects in the terminal cells.
