Expression of vgQ-lacZ in gro mutant clones. Third instar imaginal wing disks (anterior to the left and dorsal to the top) stained for GFP and β-galactosidase. Loss of GFP (green) marks clones of homozygous gro mutant cells. Ectopic vgQ-lacZ expression is detected in clones of (A) E48, (B) MB36 and (C) MB12 at the anterior and posterior edges of the wing pouch but not in clones of (D) MB5. Arrows indicate positions of gro clones at the edge of the wing pouch; GFP, green fluorescent protein; Gro, Groucho.
