Mitochondrial morphology in C. elegans body-wall muscles. a, b The percentages of muscle cells with predominantly tubular, elongated, or fragmented mitochondria in adult hermaphrodites of the indicated RNAi treatments visualized by mitochondria-targeted GFP expressed in body-wall muscle cells. P values were determined by χ ²-test. Sample size (n) of muscle cells from left to right are: a 119, 128, 152, 198, 173; and b 151, 111, 173, 125, 136. Mitochondrial morphology was scored blinded. For all panels, asterisks above bars denote P value comparisons to wild type/controls; asterisks above lines denote comparisons under the lines: ***P < 0.001; ns = not significant
