Fig. 6. Effects of Kul overexpression in the wing imaginal disc. (A) Ser expression (green) in a wild-type wing disc. (B) Overexpression of Kul by MS1096 resulted in a uniform distribution of Ser, which is punctate. The effect is more pronounced in the dorsal part of the pouch, where expression of the driver is higher. (C-G) Kul was overexpressed in the central part of the wing disc by sal-GAL4. (C) Ser expression is expanded within the sal domain. Instead of the typical membrane-associated distribution of Ser (arrow), it is detected in a punctate intracellular pattern (arrowhead). (D) Merged image showing Ser (green) and Cut (red). (E) Cut expression is expanded throughout the domain of Kul overexpression (arrow). (F,G) Expression of Wg (red) is expanded within the same domain (arrow).
