Detailed Description
Statement
Reference

Late stage ss134 embryos show defects in class I dendrite morphogenesis; primary branch overgrowth and increased terminal branching of the class I dendrites is seen. This defect persists throughout the third larval instar.

ss134/ssD115.7 mutants show defects in class I dendrite morphogenesis; primary branch overgrowth and increased terminal branching of the class I dendrites is seen.

ss134/ssaBR30-71 adults show a reduction in the size of bristles and an antenna-to-leg transformation.

Single cell ss134 clones (generated using the MARCM technique) of the ddaE neuron show increased terminal branching, while the outgrowth of primary dendrites is mostly unaffected.

Single cell ss134 clones (generated using the MARCM technique) of the ddaD neuron show increased branching and dendrite routing defects. Secondary dendrites are misoriented and branches improperly terminate posterior to the cell body.

Single cell ss134 clones (generated using the MARCM technique) of the ddaB neuron show increased dendritic branching at the distal tips of primary and secondary dendrites.

Single cell ss134 clones (generated using the MARCM technique) of the ldaB neuron show a reduction of dendritic spikes along all major branches.

Single cell ss134 clones (generated using the MARCM technique) of the ddaF neuron show a reduction in the number of dendritic spikes and show clusters of longer terminal branches along the primary dendrites.
