Figure 6: Expression of wg-GAL4 and hh-GAL4 in wild type and pb27/pb20 mutants. Panels (A)–(D) are wg-GAL4; panels (E)–(H) are hh-GAL4. Panels (A), (D), (E), and (H) show expression of UbiGFP (green). Panels (B), (C), (F), and (G) show expression of YFP (yellow) from a UASYFP reporter gene. Panels (A), (B), (E), and (F) are wild type and panels (C), (D), (G), and (H) are pb27/pb20 mutants. The arrowheads indicate expression of YFP in the maxillary palps of wild type and pb mutants at 16 h AHE.
