Fig. 5. Fas2 controls genitalia rotation cell non-autonomously. Morphology of the corpora allata nerve terminals in a wild-type (A), Fas2^spin (B) and mosaic Fas2^spinR5/Y; D2-3/+ (C) males. The number of terminal boutons is reduced in Fas2^spinR5, and is restored in mosaic males. (D,E) Phenotype of adult ring glands from non-rescued (D) or rescued (E) males, after generation of random, `flip-out' clones expressing Fas2 (not shown) and EGFP (green). Only rescued males express GFP and Fas2 in the ring gland.
