Moderate level Hh signalling despite large disp clones. Anti Ci (a) or in green (c), anti-myc (clone marker) (b) or in red (c). Even when large disp clones fill almost the entire posterior presumptive pouch (marked by lack of anti-myc staining (b)), some form of Hh is still able to up-regulate Ci accumulation near the A/P boundary (a). Arrow indicates region of Ci accumulation. Note that there is no region of hyper-activated Ci (low level of Ci as shown in Figure 1) in this part of the disc.
