The loss of ced-9 function does not cause detectable defects in mitochondrial morphology in body wall muscle cells. (A) Schematic of the mitochondrial morphologies observed in body wall muscle cells. (B) Wild-type (+/+), ced-3(n2427), ced-9(n2812); ced-3(n2427), ced-9(RNAi), fzo-1(RNAi), and ced-9(n1950gf) L4 larvae carrying a P_myo-3 mitogfp transgene were analyzed by fluorescent microscopy. Quantification of the different mitochondrial morphologies observed and the number of body wall muscle cells and transgenic lines analyzed are indicated, and quantification of the mitochondrial length is shown in Fig. S4. nuc, nucleus. Error bars indicate standard deviations.
