Figure 3. Wildtype expression pattern of Hth in haltere imaginal discs is identical to its expression pattern in wing imaginal discs.

Wing (A, B) and haltere (C, D) imaginal discs stained with anti-Wg (blue) and guinea pig anti-Hth (red) antibodies. Please note strong expression of Hth in the peripodial membrane (A, C) and in the presumptive hinge and the notum (B, D). As in wing discs, in haltere discs too Hth is not expressed in the pouch region. In this and in subsequent images, all discs are shown with anterior to the left.
