Figure 4.
DLM phenotypes in sply alleles. (a′,a″) and (b′,b″) show different corresponding sagittal sections of 5-day-old female, single Df(2R)BSC433/+ and sply05091/Df(2R)BSC433 thoraces, respectively. In (a), white arrows point out control DVM morphology, which is severely compromised in the mutant (b). A hole in the bL muscle is indicated by the red arrow in (a′) whereas in (b″) aL and bL muscle detachment from the cuticle is indicated by the red arrow, though all DLMs in this hemithorax show detachment. DLMs in the right hemithorax are all attached to the cuticle in (a″) whereas corresponding DLMs are detached and damaged in (b″). (c) Volume maps for each genotype. (d) Average DLM volumes and s.d. in each group described above. n = 3 per group.
