Ectopic expression of Hr39Scer\UAS.cBa driven by Scer\GAL4Tab2-201Y in developing γ neurons blocks pruning. Although some γ neurons seem pruned normally, 100% of the mushroom bodies predominantly display γ neurons that retain their larval characteristics. In mutant neuroblast clones, there is a mixture of unpruned and apparently pruned &gr; neurons. Similarly, in two-cell mutant clones, two mutant neurons are clearly unpruned whereas two others appear normal. Only γ neurons appear affected by Hr39Scer\UAS.cBa ectopic expression in adult mushroom body neurons.

Hr39UAS.cBa, Scer\GAL4Tab2-201Y has gamma Kenyon cell phenotype, suppressible | partially by ftz-f1β.UAS.cBa, Scer\GAL4Tab2-201Y
Co-expression of ftz-f1β.Scer\UAS.cBa in γ-neurons partially rescues the dendritic pruning found upon expression of Hr39Scer\UAS.cBa (with both transgenes under the control of Scer\GAL4Tab2-201Y).
A ftz-f1ex7 heterozygous background enhances the mutant pruning phenotype seen in flies expressing Hr39Scer\UAS.cBa in γ neurons (with both transgenes under the control of Scer\GAL4Tab2-201Y).
Expression of EcRB1.Scer\UAS in Hr39Scer\UAS.cBa neuroblast clones (under the control of Scer\GAL4Tab2-201Y) restores wild-type γ neuron remodelling.
