Ultrastructure defects of thoracic and leg muscles from 15- and 35-day-old tw mutants.
(Number of individuals that have abnormal phenotype)/(Number of individuals observed) is shown. The “rescue” genotype was [tw/Y; Act5C-Gal4/+; UAS-tw/+]. A muscle area of 590 µm2 per individual was observed.
*: The number of abnormal phenotypes in the muscle area of 590 µm2 per individual was counted and the percentage of abnormal structures (Number of abnormal structures/Number of structures observed) was calculated and is shown in Figure 6. SR, sarcoplasmic reticulum.
