FIG. 4.
Effects of overexpressing CKIɛ in adult wings. (A) Wild-type wing pattern in the region distal to the posterior cross vein. The arrow indicates hair orientation. (B) Ectopic bristles were observed in wings with CKIɛ overexpression (indicated by arrowheads), similar to ectopic Wg signal activation in the interior of the wing. (C and D) Further polarity defects are shown here in wings overexpressing CKIɛ (C), similar to the phenotypes observed in dsh1 (D). Arrows indicate irregular orientations of the hairs.
