Expression of GSd239GSd239 under the control of Scer\GAL4109(2)80 results in defects in the dendrites of dorsal cluster dendritic arborisation (da) neurons in third instar larvae: dendrite morphology is defective in the class III da neurons and the length of higher order branches is reduced (with no obvious reduction in branch number) in the class IV da neurons.
Isolated RP2 neuron clones expressing GSd239GSd239 under the control of Scer\GAL4Act5C.PP (clones generated using the Scer\FLP1eve.RN2 line) show altered distribution of dendrites in the dendritic field at 25-31 hours after egg laying: the number of dendrites targeted to anterior regions is decreased, the number targeted to posterior regions is increased, and the number targeted to medial regions is decreased.
