Figure 2. Notch acts at the level or downstream of yki.

Figure 2

A. Over-expression of Yki along the A/P boundary of the wing disc using dpp-Gal4 (along the line indicated by the yellow arrow), leads to the strong increase in expression of ex-lacZ in the pouch (red; A′), except at the D/V where Notch activity is highest (yellow arrowhead). B. When co-expressed with Yki (using dpp-Gal4; yellow arrow), Nicd imposes an inhibition of ex-lacZ expression in the pouch (red; B′; yellow arrowhead) but not at the periphery. E-Cadherin staining (green, A; B) outlines all cells.
