Fig. 3. Dpp signalling represses IroRE2-lacZ. (A-C') tkva12 mutant cells (absence of green), upregulate IroRE2-lacZ (red, arrows) in the prospective medial notum (A,A'), lateral notum (B,B') and hinge (C,C'). (D,D') Overexpression of UAS-tkvQD in clones of cells (green) abolishes expression of IroRE2-lacZ (arrows).
