In situ hybridizations on predicted direct targets of Ey. (A,B) shf probe on wild-type (A) and dpp-GAL4/UAS-ey (B) eye-antennal discs. shf is expressed at the anterior margin of the disc and in scattered cells posterior to the morphogenetic furrow. (C,D) Optix probe on wild-type (C) and dpp-GAL4/UAS-ey (D) eye-antennal discs. Optix is expressed anterior to the morphogenetic furrow. Arrowheads in A and C indicate endogenous expression; arrows in B and D indicate up-regulation of expression in the ventral dpp expression domain of the antennal disc. (dpp>ey) dpp-GAL4/UAS-ey.
