Fig. 6. The effects of EN-HTH^1-430 and EN-XMeis3^1-333 on derivatives of the wing, labial and genital discs. (A-C) Cuticle preparations of wings from dpp-Gal4/UAS-EN-HTH^1-430 flies. (A) Low magnification showing the general organization of the affected wing. The arrow indicates the bristles of the anterior wing margin. (B) Higher magnification of the proximal region, which is covered by bracted bristles (arrowheads). The arrow indicates the bristles of the anterior wing margin. (C) Higher magnification of the anterior wing margin bristles concentrated in a small region of the proximal portion of the wing. (D) A dpp-Gal4/UAS-EN-HTH^1-430 fly exhibiting a duplication of the wings. Extra wings are indicated by arrows. (E-F) Cuticle preparation of mouth parts of a wild-type (E) and a dpp-Gal4/UAS-EN-HTH^1-430 fly (F). Note the outgrowths with bracted bristles on the labellum in F (arrow). (G) Cuticle preparation of a dpp-Gal4/UAS-EN-XMeis3^1-333 fly showing a typical outgrowth from the anal region (arrows). (H-I) Genital discs of a wild-type (H) and a dpp-Gal4/UAS-EN-XMeis3^1-333 (I) larvae. Note the abnormal morphology and hyperplasia of the presumptive anal region in I (arrows).
