Embryos expressing SdcPA.Scer\UAS.T:Zzzz\FLAG,T:Avic\GFP under the control of Scer\GAL4Mz97 show consistent ectopic recruitment of Gat[+] astrocyte processes to the dorsal surface of the central nervous system and at least one patch of ectopic processes per ventral nerve cord.
SdcPA.UAS.Tag:FLAG,GFP/Scer\GAL4sim.P3.7 fails to rescue Sdc23
SdcPA.UAS.Tag:FLAG,GFP/Scer\GAL4repo.PU fails to rescue Sdc23
Scer\GAL4elav.PU-, Scer\GAL4da.G32- or Scer\GAL4Mef2.PR-mediated expression of SdcPA.Scer\UAS.T:Zzzz\FLAG,T:Avic\GFP fully rescues the Sdc23 ventral midline fascicle cross-over phenotype. In contrast, Scer\GAL4sim.P3.7- or Scer\GAL4repo.PU-mediated expression does not rescue.
