FIG. 2.
dGcn5 is required for cell proliferation in imaginal tissues. (A) Reduced and misshapen imaginal wing disks from homozygous Gcn5E333st mutants compared to a wing disk from a Gcn5E333st/TM3 control third-instar larva. (B) Wings from control animals (+/+) and en-GAL4/UAS-IR[Gcn5] adult escapers with vein and cross-vein defects (black arrows) in the smaller posterior compartment. (C) Wings from vg-GAL4/UAS-IR[Gcn5] adult escapers. (D) Complete absence of abdominal adult cuticle in esg-GAL4/UAS-IR[Gcn5] pharate adults compared to a control animal (+/+).
