Fig. 6. AC is insensitive to inhibition by Torso. In situ hybridisations were performed on blastoderm embryos with a lacZ probe. Embryos were from bcd^E1 females carrying two copies of the AC (A), QAC (B), A (C) and C (D) transgenes (Schaeffer et al., 1999), from wild-type females (E), from bcd^E1 females carrying one copy of AC (F), from tor⁴⁰²¹ females (G), and from tor⁴⁰²¹ bcd^E1 females carrying one copy of AC (H). Females were crossed with males carrying the UASp-lacZ transgene.
