Effects of Caudal binding sites on dE2F expression in vivo. β-Galactosidase expression in the wild-type (Oregon R) (A) and transgenic flies carrying E2F-lacZ (B) and E2Fcadmut-lacZ (C) was detected by X-gal staining. The adult guts were dissected and stained with 0.2% X-gal solution in the dark. Reduced expression of the E2Fcadmut-lacZ is apparent in the posterior midgut and hindgut, compared with E2F-lacZ. The arrow indicates the posterior midgut and the arrowhead the hindgut. The asterisk indicates the Malpighian tubules.
