Overexpression of Dscam1A-17.2-19+23.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4ppk.PG induces exuberant presynaptic overgrowth.
Scer\GAL4ey-OK107-mediated expression of Dscam1A-17.2-19+23.Scer\UAS.T:Avic\GFP in Dscam1unspecified clones (using the MARCM/GAL80 system) show the multibranch/lobe phenotype in 16% of cases, and a single-branch/neuron phenotype in 11% of cases.
Scer\GAL4ey-OK107-mediated expression of Dscam1A-17.2-19+23.Scer\UAS.T:Avic\GFP in wild type clones (using the MARCM/GAL80 system) has hardly any effect: axon bifurcation at the peduncle terminus is suppressed in only 3% of cases.
Scer\GAL4ey-OK107/Dscam1A-17.2-19+23.UAS.GFP partially rescues Dscam1unspecified
Scer\GAL4ey-OK107-mediated expression of Dscam1A-17.2-19+23.Scer\UAS.T:Avic\GFP in Dscam1unspecified clones (using the MARCM/GAL80 system) reduces the multibranch/lobe phenotype from 97% to 16% of cases.
