Detailed Description
Statement
Reference

The phenotypes produced by Fmr1I307N.Z.Scer\UAS are similar but consistently weaker than those produced by Fmr1Scer\UAS.cZa. When expression is driven by Scer\GAL4elav-C155 flies show abnormally outspread wings and cannot fly. Flies are uncoordinated and show adult lethality - dying 5-10 days post-eclosion. When expression is driven by Scer\GAL4Mhc.PW flies' wings are droopy or held up and they cannot fly. When expression is driven by Scer\GAL4G7 flies show pupal lethality. When expression is driven by Scer\GAL4hs.2sev the retina is disordered with misshapen rhabdomeres, abnormal rhabdomere numbers and fused ommatidia. Phototransduction is normal, however synaptic transmission is reduced (as indicated by a reduction in off-transient mean amplitude as assayed by ERG).
