Dorsal longitudinal muscles of Mhc1/+ individuals expressing MhcUAS.cDa under the control of Scer\GAL4Mef2.PR show relatively normal muscle fibers and Z- discs, despite of a small frequency of fiber splitting. The pupal stage of these individuals takes longer than in controls. Adults show a mild reduction in climbing ability, as compared to controls.
Dorsal longitudinal muscles of individuals expressing MhcUAS.cDa under the control of Scer\GAL4Mef2.PR do not show any obvious defect.
