Scer\GAL4how-24B-mediated expression of tnScer\UAS.cLa rescues the thin pupal phenotype, the thin and loose larval skeletal musculature, and larval myofiber instability and unbundling phenotypes of tnΔA/Df(2R)Exel6068 animals. Unlike tnΔA/Df(2R)Exel6068 animals, the rescued animals mostly eclose as adults.
