Fig. 4. Expression of Fas2 in neurons innervating the corpora allata rescues Fas2^spin rotation defects. (A) Summary of rescue experiments using lines expressing GAL4 in different subsets of neurons in the brain. Rescued males had the following genotype: Fas2^spinR5/Y; UAS-Fas2; GAL4. +++, full rescue; +, partial rescue; –, no rescue. (B) Ring gland expressing a synaptobrevin-GFP fusion protein (green; to mark terminal boutons) in neurons innervating the corpora allata (nCA), using the Kurs21-GAL4 line. The ring gland (outlined) is double stained with anti-Fas2 (red). (C) Ring gland expressing EGFP (green) in neurons innervating the prothoracic gland (nPT), using the Feb211-GAL4 line. The ring gland (outlined) is double stained with anti-Fas2 (red).
