(B) Pcex - 1:: unc - 7S:: gfp (AVA, AVD interneurons) rescues forward locomotion but does not concentrate in puncta near B cell bodies. (neuraldevelopment.biomedcentral.com)
As expected, this construct (minus F56B12) rescued forward but not backward locomotion, and UNC - 7S was strongly expressed as puncta in the nerve ring and ventral nerve cord, but not the dorsal nerve cord (consistent with lack of DA and DB motor neuron expression).

We can only speculate as to why there is a wider distribution of UNC - 9:: GFP puncta in an unc - 9 background. (neuraldevelopment.biomedcentral.com)
