Expression of GSd219GSd219 under the control of Scer\GAL4109(2)80 results in reduced dendrite branching in the class IV dorsal cluster dendritic arborisation neurons in third instar larvae.
Fas2-positive axon bundles in the ventral nerve cord are missing or disrupted and are diffuse or less distinct than normal in embryos expressing GSd219GSd219 under the control of Scer\GAL4scrt-11-6.
