Fig. 8. lines specifies distal pouch fates and inhibits proximal hinge fate at the third instar. (A,C-H) Late third instar lines mutant FLP/FRT clones. (B) drm-expressing clones. Arrowheads in A and B indicate planes of z-sections shown in A',A'',B',B''. Arrows in C-H indicate magnified regions shown in insets. (A) Bowl (red) and GFP (green). (A-A'') lines mutant clones and (B-B'') drm-expressing clones extruded basally (arrows in A' and B'). (C-C'') Tsh, (D-D'') Hth and (E-E'') Wg, the expression of which overlaps in the hinge, were ectopically expressed in these clones. The expression of these proteins increased at a distance from the AP compartment boundary. (F-F'') Expression of Nub, which localizes to both the pouch and distal hinge was unaffected. (G-H'') The expression of the wing specific proteins (G) Dll and (H) Sal was lost from the clones.
