Fig. 4. wg and dachs are required for overgrowth in fat
mutant discs. Discs stained for VG (green) and NUB (magenta); discs shown in
A-F are at 36-48 hours of third instar, those in G-H are at 48-60 hours. Cells
that express only NUB correspond to the distal half of the proximal wing
(Fig. 1). (A) Wild-type. (B)

dachs1. (F) fat8 dachs1.
(G) fat8/fatG-rv disc, the overgrowth
of the proximal wing is even more pronounced at this age, and the wing becomes
highly folded. (H) wgspd-fg
fat8/wgspd-fg fatG-rv. Wild
type and fat8 dachs1 are not shown at this age,
as they begin to pupate. Scale bar in B: 80 µm for A-H.
