Figure 1. Ey repression at the morphogenetic furrow is necessary for differentiation.

Figure 1

(A) Cubitus interruptus (Ci), Eyeless (Ey), and Senseless (Sens) expression in a w1118 third instar eye-antennal imaginal disc. (A′) Strong Ci accumulation marks the morphogenetic furrow. (A″) Ey expression; white arrow marks cuboidal margin cells, yellow asterisk marks ventral head capsule. (A′″) Sens expression shows R8 differentiation. (B–D) Yellow arrow marks the morphogenetic furrow: (B) Sine oculis (So) expression, (C) Eyes absent (Eya) expression, (D) Dachshund (Dac) expression. (E) Overexpression of Ey posterior to the morphogenetic furrow using Flipout-Gal4 inhibits photoreceptor differentiation. (E′) ELAV from panel E showing differentiation. (E″) Eyeless expression from panel E.
