Fig. 5. Mitochondria are lost from SdhA mutant terminals. (A-P) Cross section of the lamina neuropil in wild type (A-D,I-L), and SdhA¹¹¹⁰ mutant eye-specific mosaic (E-H,M-P) animals, stained with the R cell-specific antibody mAb24B10 (A,E,I,M), for mitochondrially localized GFP (B,F,J,N), or for the mitochondrial complex V subunit alpha (C,G,K,O), at 0 (A-H) or 5 days (I-P) after eclosion. Merged images are shown in D,H,L,P. Insets show single synaptic cartridges. Scale bar: 10 µm.
