Figure 5.

Comparison of ending points of l(2L)MB397 mutant axons and arborization points of wild-type axons. The distance from the ending points of l(2L)MB397 mutant axons or the branch points of wild-type axons to the midline were measured and compared. In the wild-type γ axons, each dot represents the distance from the first branch point of a single neuron to the midline of the brain. In the l(2L)MB397 mutant γ axons, each dot represents the distance from the ending points of axons to the midline. Only truncated l(2L)MB397 mutant γ axons without major axon arbors were examined. In the case of wild-type β′ axons, the distance from the proximal arborization point (the right cluster) or the first arborization point of the distal cluster of arbors (the left cluster) to the midline were measured separately. Note that ending points of l(2L)MB397 mutant β′ axons fall into two clusters, close to the arborization point of wild-type β′ axons. Numbers in parentheses represent the total number of neurons analyzed.
