scarf is regulated by JNK in leading edge cells. (A) Genomic organization of the scarf locus. P element (KG05129) and piggyBac (PBss and M13.M2) insertions (blue triangles), the scarf Δ1.5 deletion (green), exons (white boxes) and the open reading frame (red boxes) are shown. (B–G) Embryos of stages 12–14 labelled to visualize β-gal, GFP or scarf mRNA expression. (C) The bottom panel shows a cross-sectional view. (D) Magnifications of the boxed tissues are shown. Scale bars, 25 μm. ap, apical; AS, aminoserosa; bs, basal; GFP, green fluorescent protein; JNK, c-Jun amino-terminal kinase; LE; leading edge; mRNA, messenger RNA.
