Expression of GSd302^GSd302 under the control of Scer\GAL4^109(2)80 results in defects in the dendrites of dorsal cluster dendritic arborisation (da) neurons in third instar larvae: there is a severe reduction of higher order branches in class III and IV da neurons, although the growth of primary branches appear intact.

Isolated RP2 neuron clones expressing GSd302^GSd302 under the control of Scer\GAL4^Act5C.PP (clones generated using the Scer\FLP1^eve.RN2 line) show a reduction in dendrite growth at 25-31 hours after egg laying. The distribution of dendrites in the dendritic field is altered: there is a decrease in the number of dendrites targeted to the anterior, posterior, medial and lateral regions of the dendritic field.

Fas2-positive axon bundles in the ventral nerve cord are missing or disrupted in embryos expressing GSd302^GSd302 under the control of Scer\GAL4^scrt-11-6. In the periphery, the SNa and SNc motor neurons are missing or thinned, and the ISNb motor neuron is stalled or misrouted.
