Fig. 2. Modulation of Nemo affects the spacing of veins and wing cell density. (A-C) Comparison of intervein distances between wild-type (A) and nmo^adk2/nmo^adk2 (B) Drosophila wings. (C) Superimposition of the two wings, showing that nmo L2 and L5 veins (arrows) are spaced further apart than in the wild type. (D-F) Comparison of intervein distances between an omb-Gal4/+ control (D) and omb-Gal4/+; UAS-nmo/+ (E). (F) Superimposition of the two wings, showing that omb>nmo L2 and L5 veins (arrows) are closer together than in the omb-Gal4 control. (G) A wild-type wing with the numbering scheme depicted for the measured intervals, 1-4. (H) Measurement of intervein regions in the wild type, omb-Gal4/+, omb>nmo and nmo^adk2. (I-L) Cell density within a given region in the wing blade of the wild type (I,J) and nmo^adk2/nmo^adk2 (K,L) was calculated by counting trichome density in the indicated squares (I,K; the location of the counted regions is indicated with an asterisk in J,L). The results are shown in Table 1.
