Homozygous single-cell and neuroblast projection neuron clones lack dendritic and axonal terminal arborisations.
Adult mushroom body γ neuron single-cell homozygous clones show a significant reduction in the number of dendritic branches and dendritic claws compared to wild type. The number of terminal axonal branches is also severely reduced in the mutant cells. The axons of the mutant γ neurons often end at the peduncle position.
Selected as: a fly that has lost the ry+ marker of the P{PZ} element present in Aats-trp03559.
Excision of the P{PZ} element.
