Fig. 2. The Drosophila gene vestigial is necessary and sufficient to activate nab expression. (A) nab expression in a vg283b27r wing disc. Expression in the wing pouch is lost; only basal expression remains in the notum. (B,B') Clones of vg-expressing cells (green) showing expression of wg (red) and nab (blue): y w hsFLP122; Act5C>y+>Gal4 UASGFP/UASvg. Insets at the bottom show the individual channels of the selected areas in B and B'. (B) vg misexpression activates nab nonautonomously in a broader domain.
