FIG. 5.
snr1 is required for proper eye and abdomen development. Scanning electron micrographs (150×) of adult eyes from flies raised at 18°C are shown. (A) Wild type; (B) snr1E1/snr1E1; (C) snr1E1/snr1R3. Note the reduced eye size, irregularly shaped ommatidia, and fused or missing interommatidial bristles in panels B and C. (D) Magnified (2,000×) view of an eye from an snr1E1/snr1E1 fly showing duplicated and fused interommatidial bristles. (E and F) Abdominal pigmentation in similarly aged adult males. Shown are lateral views of wild-type (E) and snr1E1/snr1R3 (F) flies raised at 25°C with segments A2 to A6 indicated. Arrows in panel F indicate ectopic pigmentation in the anterior portions of the A3 and A4 tergites.
