Figure 7


Fig. 7. Ft does not regulate Wg expression in the distal wing. (A) Expression of Wg (red) in the DV boundary (arrowhead) and in the inner (IR) and outer (OR) rings of the hinge region (arrows) in wild-type disc. (B) In ftfd mutant disc, levels of Wg expression in the DV boundary are comparable with that of wild-type discs (A), while in the hinge region (arrows) its expression is upregulated and broadened. (C-C') ft422 mutant clones (marked by loss of GFP, green) spanning the DV boundary (asterisks) do not affect Wg (red) expression, while in the hinge region its expression is upregulated (arrows).
