Isolated RP2 neuron clones expressing GSd499GSd499 under the control of Scer\GAL4Act5C.PP (clones generated using the Scer\FLP1eve.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.
