Fig. 6. Patterns of sal (A-H) and brk (I-L) expression in wing discs. (A) Wild type. (B) ash2^I1/ash2^I1 showing reduced sal expression. (C) ash2¹¹²⁴¹¹/ash2¹¹²⁴¹¹. (D) net¹/net¹; ash2¹¹²⁴¹¹/ash2¹¹²⁴¹¹. (E) bs⁰³²⁶⁷/+; ash2¹¹²⁴¹¹/ash2¹¹²⁴¹¹. (F-H) ash2^I1 mutant clones, marked by the absence of GFP. (G) salm expression is reduced in ash2^I1 clones. (H) Merged green and red channels. (I) brk expression is visualised by means of the brk-lacZ reporter X47 in a wild-type wing disc. (J) High magnification of the boxed area indicated in I, ash2^I1 clones lack GFP. (K) There is no change in ß-galactosidase expression in ash2^I1 mutant cells. (L) Merged images of J and K. Scale bars: 20 µm.
