Fig. 8. Synapses are formed in unc-119(ed3) mutants. (A) Dorsal view of a wild-type adult animal expressing GFP-tagged synaptobrevin in the DD neurons located in the dorsal nerve cord. DD synapses (arrow) were uniformly distributed along the dorsal nerve cord. (B) Dorsal (DD) synapses in unc-119(ed3) young adults were present but discontinuous because of large gaps in the dorsal nerve cord. (C) Ventral view of a wild-type adult expressing GFP-tagged synaptobrevin in the VD synapses of the ventral nerve cord. VD synapses were located along the ventral nerve cord of wild-type worms (arrow). (D) The distribution of VD synapses in the ventral nerve cord of unc-119 adults was abnormal. A lateral branch that formed synapses is indicated by an arrowhead. Scale bars 10 µm.
