Fig. 8. eyg can suppress wg expression. (A) wg-lacZ expression in a wild-type eye-antennal disc. (B) The expression in the dorsal and ventral poles of the eye disc were suppressed in dpp>eyg, and in dpp>ey (not shown). Note the posterior margin and the dorsal overgrowth express wg-lacZ. (C) The wg-lacZ expression domain expanded to the posterior margin in the eyg¹ mutant eye disc. The eye disc was significantly reduced. (D) wg-lacZ expression in a wild-type wing disc. The expression in dpp>eyg (E) was suppressed in a region where the wg expression domain intersects the dpp expression domain (^*). The dpp-GAL4 expression domain was visualized by dpp>lacZ (F). wg-lacZ was similarly suppressed by dpp>ey in wing disc (not shown).
