Expression of btl::EgfrScer\UAS.cDa under the control of Scer\GAL4btl.PS at both 18oC and 25oC in btlH82Δ3 embryos can rescue all primary branches of the tracheal system, although at reduced frequencies. Many embryos have dorsal and ganglionic branch defects in half or more of the segments. The lateral trunk fuses only sporadically, although the dorsal trunk shows complete fusion in most embryos. The visceral branch is misguided in some embryos. The number of terminal tracheal cells is significantly reduced compared to wild type. Expression of btl::EgfrScer\UAS.cDa under the control of Scer\GAL4btl.PS significantly rescues tracheal development in btlH82Δ3 stumps09904b double mutant embryos. The dorsal trunk is disrupted in some embryos, some dorsal branches are missing or misguided and the lateral trunk fails to fuse. Some of the ganglionic branches fail to form and do not migrate in the proper direction.
