Fig. 8. Dpp and EGFR pathways activate IroRE1-lacZ expression. Cells expressing activated forms of Tkv (A,A') or Raf (C,C') (green) activate IroRE1-lacZ (red) at the prospective lateral notum (arrows) but not at the wing hinge, wing pouch or proximal notum (arrowheads). lacZ expression (red) strongly decreased (arrows) in tkva12 (B,B') or UAS-RafDN (D,D') clones.
