(A-F) Dorsal surface of adult wings from UAS-dco/+; en-GAL4/+ (A,D), UAS-dco/+; en-GAL4/DAnkrd49l(2)35Be4 (B,E) and UAS-dco/+; en-GAL4/+; BdbtΔ79.1/+ (C,F) female flies, raised at 25°C. (A-C) Images near the posterior cross vein. (D-F) Images around vein 4 near the distal tip of the wing. The yellow line marks the area of wing in which trichomes swirl. Scale bars 100 μm. (G) Quantitation of the area of wing in which trichomes swirl, in 10 wings of the genotypes from A-F. Samples were compared to UAS-dco/+; en-GAL4/+ using one-way ANOVA with Dunnett's multiple comparisons test, ***p≤0.001. Error bars are 95% confidence intervals. See S2 Table for numerical data.
