Fig 10. Repression of cut by Tsh/Tio is independent of the retinal determination network.

(A,D,G) cut expression in the antennal disc of ey^LB, so¹, and eya² mutant antennal discs. Note that in these mutants cut expression is identical to wild type. (B,C,E,F,H,I) Loss of cut expression when tsh (B,E,H) or tio (C,F,I) continues to be expressed in the antenna with dpp-GAL4. Orange arrows demarcate zones where cut expression is down regulated. Yellow asterisks mark the duplicated antennal segments. Posterior is to the right. (Scale bars, 50 μm).
