Summary of the D-Type Motor Neuron and Axon Phenotypes of Stu Mutants.

*The number in the bracket is the total mutant number examined.**Circumferential defects include premature stop or inappropriate branching. L-R defect refers to the D-type neuron commissures that extend from left side of the animals. Longitudinal extension defects were scored as regions that lack GFP-labeled axons.***N/A: not available.
