The loss of ced-9 function does not cause detectable defects in mitochondrial morphology in embryos. (A) Schematic of the mitochondrial morphologies observed in embryos. (B) Mitochondria of wild-type (+/+), ced-3(n2427), ced-9(n2812); ced-3(n2427), ced-4(n1162), ced-9(n2812); ced-4(n1162), ced-9(n1653ts), ced-9(RNAi), and ced-9(n1950gf) embryos were stained using TMRE, as indicated in Materials and methods. Quantification of the different mitochondrial morphologies observed and the number of embryos analyzed are indicated. Videos 6 and 7 show 3D reconstructions of wild-type and ced-9(n1653ts) embryos marked with asterisks.
