Graphical comparisons of median diameter between different genotypes and their statistical significance. The line charts (top panels in a and b) compare median muscle diameters of populations of muscles expressing different RNAi constructs. The data were collected over a period of 120 hours from 10 pupae per genotype. For each population, statistics were derived from 10 muscle cells. The red and green lines show the median diameter, while the adjacent shaded regions indicate 25th and 75th percentiles. The horizontal dotted lines in the significance graphs (bottom panels) represent the p-value 0.01. Due to the negative log scale, measurements of significant difference are shown above the line. (a) Silencing of Atg9 caused decreased muscle atrophy compared to controls from 30 hours AHE onwards. Prior to 30 hours AHE, no significant difference were observed between the two genotypes. (b) Silencing of Tor lead to an enhancement of developmental atrophy. The graph shows that the thinning of muscle fibers proceeds for a longer period (45 as opposed to 30 hours AHE) than in control.
