Adults expressing sandUAS.cAa under the control of either Scer\GAL4tin.CΔ4 or Scer\GAL4Act5C.PU do not exhibit obvious defects in heart morphology or function (fractional shortening).
Expressing sandUAS.cAa under the control of either Scer\GAL4tin.CΔ4 or Scer\GAL4Act5C.PU rescues the cardiac defects observed in Df(2R)Exel7094 mutants (i.e. enlarged cardiac chamber and decreased fractional shortening).
