Figure 5. dpn regulates Cut expression.

dpn downregulation, mediated by en>RNAi, in the posterior compartment of late (B-B′′) and early (C-C′′) third instar wing discs. GFP-RNAi was used as a control (A-A′). Discs were stained with Cut (red) and Dpn (green). Yellow brackets (B′-B′′ and C′-C′′) represent the Cut expression at the posterior D/V boundary.
