Mitochondrial dysfunction prevents Delta trafficking independent of developmental arrest. (A–F) Whole ovariole images and images of Delta stained ovarioles from RNAi transgenes for known mitochondrial genes, including control, PHB2-RNAi, ATP5CF6-RNAi, Bor-RNAi, Cype-RNAi, and tomm22-RNAi. Whole ovary images represent females with two copies of the matα-GAL4 driver and immunofluorescence images ovarioles from females carrying one-Copy of the matα-GAL4 driver. (G–L) Whole ovariole images and images of Delta stained ovarioles from RNAi transgenes for non-mitochondrial genes including Fib-RNAi, Nob5-RNAi, HSC-70-4-RNAi, Prosalpha7-RNAi, Prosbeta5-RNAi, and OCT1-RNAi. Whole ovary images represent females with two copies of the matα-GAL4 driver and immunofluorescence images ovarioles from females carrying one-Copy of the matα-GAL4 driver.
