Fig. 1. Characterisation of btlGal4UAS-tauGFP-801 tracheal phenotypes. (A) Wild-type stage 14 embryo. (B) Stage 14 embryo showing defects in the formation of some DBs and GBs (arrowheads), and branch breaks (arrows). (C,D) Detail of five tracheal metameres focused on the DBs (C) or the GBs (D) of late stage 15 embryos. Note the presence of broken branches leaving a few cells completely isolated from the rest of the tree (arrowheads), and of branches with cells connected by cytoplasmic extensions (arrows).
