A held-up wing phenotype is seen in 10-15% of flies expressing Rnor\Otcd.Scer\UAS under the control of Scer\GAL4da.G32 beginning at 3 days after eclosion. The indirect flight muscles contain mitochondrial aggregates. Ultrastructurally, the muscle structure is highly disorganised, and vacuolisation and fragmentation of mitochondrial cristae is seen. The flies show an age-dependent impairment in climbing ability and are short lived compared to wild type.
Rnor\Otcd.UAS, Scer\GAL4da.G32 has abnormal locomotor behavior | adult stage | progressive phenotype, suppressible by parkUAS.cGa, Scer\GAL4da.G32
Rnor\Otcd.UAS, Scer\GAL4da.G32 has mitochondrion phenotype, suppressible by parkUAS.cGa, Scer\GAL4da.G32
Rnor\Otcd.UAS, Scer\GAL4da.G32 has indirect flight muscle cell phenotype, suppressible by parkUAS.cGa, Scer\GAL4da.G32
Co-expression of parkScer\UAS.cGa rescues the age-dependent defect in climbing ability seen in flies expressing Rnor\Otcd.Scer\UAS under the control of Scer\GAL4da.G32. The defects in indirect flight muscle structure and mitochondrial integrity are also suppressed.
Co-expression of parkScer\UAS.cGa is no longer able to suppress the defects in climbing ability and indirect flight muscle structure seen in flies expressing Rnor\Otcd.Scer\UAS under the control of Scer\GAL4da.G32 when the flies are also mutant for Atg1Δ3D.
