      Expression of btl::torScer\UAS.cDa under the control of Scer\GAL4btl.PS at both 18oC and 25oC in btlH82Δ3 embryos results in substantial rescue of tracheal defects. Most tracheal branches develop properly and fusion between adjacent metameres occurs in most segments. Occasionally, dorsal branches are missing and the lateral trunk fails to fuse in between some tracheal metameres. The general pattern of the tracheal system is restored, although the tracheal tree has a "felted" phenotype, with fine branches extending from many positions. Ectopic formation of terminal tracheal cells is seen. Expression of btl::torScer\UAS.cDa under the control of Scer\GAL4btl.PS significantly rescues tracheal development in btlH82Δ3 stumps09904b double mutant embryos. Ganglionic branches are rescued almost completely, dorsal branches develop in more than 50% of segments and dorsal trunk fusion occurs efficiently. The lateral trunk does not fuse in these embryos and ectopic terminal cell formation is seen.
