Fig. 7. Touch cell axon guidance defects. Typical PLM axon guidance defects of smp-1 (ev715) and smp-2 (ev709) visualized with a mec-7::gfp integrated transcriptional reporter. Wild-type PLML and PLMR axons migrate longitudinally in a ventrolateral position (A,B), whereas in smp-1 and smp-2 mutants, these axons exhibit abnormal migratory paths (C,D) and branching defects (E,F).
