Figure 2. — CED-9 promotes mitochondrial fusion, whereas FZO-1 promotes mitochondrial aggregation in body wall muscle cells. (A) Schematic of the mitochondrial morphologies observed in body wall muscle cells. (B) Transgenic lines expressing mitogfp alone (P_myo-3 mitogfp), in the presence of ced-9(wt) (P_myo-3 mitogfp + P_myo-3 ced-9(wt) (3′UTRsmg)), or in the presence of fzo-1 (P_myo-3 mitogfp + P_myo-3 fzo-1 (3′UTRsmg)) were grown at 25°C to allow the expression of the smg-inducible transgene, as indicated in Materials and methods. These lines, as well as drp-1(RNAi) animals and lea-1(RNAi) animals (control(RNAi)) 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. nuc, nucleus; arrows, fused mitochondria; arrowheads, aggregated mitochondria. Error bars indicate standard deviations.
