Single cell leg motoneuron clones expressing commScer\UAS.T:Avic\GFP-m6 induced 48 hr after hatching have the following phenotypes: dendrites shift towards the midline; the mean centre of mass is shifted toward the midline compared to controls; the mean 33rd percentile of arborization is shifted towards the midline.
Single cell leg motoneuron clones expressing commScer\UAS.T:Avic\GFP-m6 induced 96 hr after hatching have the following phenotypes: dendrites enter medial territories within the neuropil with several branches terminating on the midline; the mean centre of mass is shifted toward the midline compared to controls; the mean 33rd percentile of arborization is shifted towards the midline. In a dorsoventral plane, these clones show a redistribution of dendrites into posterior and very dorsal neuropil, whilst arbor is entirely lost from ventral domains.
Pan-neural expression of one copy of commScer\UAS.T:Avic\GFP-m6 under the control of Scer\GAL4unspecified results in a robo phenocopy in which a subset of longitudinal axons are misdirected across the midline. Pan-neural expression of two copies of commScer\UAS.T:Avic\GFP-m6 under the control of Scer\GAL4unspecified results in sli phenocopy in which the majority of axons extend at the midline.
