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.
