Fig. 4. Rescue of rhabdomere degeneration in w;Trp365. In comparison to wild-type flies, w;Trp365 homozygous flies show severe rhabdomere degeneration (A). This can be rescued by su(40);Trp365 (C) but not in su(100);Trp365 (B) double mutants. The effect of su(1) on Trp365 was equivalent to that of su(100) with minimal, if any, rescue of rhabdomere structure (D). Arrows indicate rhabdomeres.
