Fig. 3. The competence to specify bracts is spatially restricted. hsp70-GAL4/UAS-Raf * pupae heat shocked for 30 minutes at 37°C. (A) In the leg, all trichomes are transformed into bracts (compare with Fig. 1A). (B) In the wing, only cells in the proximal costa (arrow) are transformed (compare with Figs 1C,D). (C) In the notum, many bracts (arrows) appear among dorsocentral bristles. (D) In the haltere, only a region of the pedicellum shows extra bracts. In A,B,D, distal is rightwards. In C, anterior notum is left.
