Activation of Yki suppresses eye fate through Wg signaling-mediated induction of Hth. Panels show effects of co-expression of activated yki and sgg with bi-Gal4 (bi>yki-GFP, sggS9A) on expression of (A,A′) Wg, (B,B′) Hth and (C,C′) Tsh in the DV margin of eye imaginal disc. The orientation and magnification of imaginal discs are identical in all panels.
