Repression of Wg responses; P/D transformation of lin^G1 clones in the wing disc. (A-A″) Nub repression (green in A,A″) in lin^G1clones induced in a wing disc (lack of red, arrowheads in A-A″). Inset in A shows Nub expression in the wild-type wing disc. (B) Proximal part of an adult wild-type wing. (C) Proximal part of a wing containing lin^G1 clones labeled by the cuticle marker forked. Arrowheads indicate ectopic macrocheatae. (D,D′) Hth ectopic expression (red) in MARCM lin^G1 clones overexpressing Arm^S10 (labeled with GFP, green). (E,E′) Nub repression (green) in random clones co-expressing Drm and dTcf (red in E). (F,H,J) Wild-type expression of Zfh-2 (F), Tsh (H) and Hth (J) in the wing disc. (G,G′,I,I′,K,K′) Ectopic activation of Zfh-2 (red in G,G′), Tsh (green in I,I′) and Hth (red in K,K′) in lin^G1 clones (labeled with GFP in G and K, and lack of red in I). All clones were induced between 48 and 72 hours AEL.
