Fig. 7. Decreased Rho1 activity rescues the shortening of Dpp signaling compromised cells. (A-C) x-z sections of late third instar wing discs coexpressing Dad and p35 with Rho1^N19 (A), sqh^dsRNA (B) or Mbs^N300 (C) in the dorsal compartment 52 hours after temperature shift to inducing conditions and stained as indicated. The apical-basal length of dorsal cells and control ventral cells is comparable (double-sided arrows). (D) The ratio of apical-basal length between dorsal and ventral cells of the experiments shown in A-C. Means ± s.e.m. are depicted [n=14 wing discs (control); n=3 (mbs^N300, p35); n=8 (GFP, dad, p35); n=8 (Rho1^N19, dad, p35); n=6 (sqh^dsRNA, dad, p35); n=12 (mbs^N300, dad, p35)]; ^*P<0.001. Scale bars: 20 µm.
