(A) Cross section of an antennal disc showing expression of Cut and D4/lacZ. The distal boundary of Cut expression and the proximal boundary of D4/lacZ expression closely match, although a few cells at the interface often express both (arrows). (B) Antennal disc stained for expression of Hth and D4/lacZ. The distal boundaries of expression coincide precisely. (C - E) Expression of D4/lacZ (red) is lost within clones mutant for Dll (C), hth (D), or exd (E). All clones are marked by the loss of GFP (green). (F,G) Clones expressing either Antp alone (F) or both Antp and Hth (G) (green) fully repress D4/lacZ (red). Expression of Hth was confirmed by antibody staining (not shown).
