the
uig-1 promoter drives expression in the pharynx, vulva, hindgut and a subset of neurons in the head and tail of C. elegans. To examine whether
uig-1 is expressed in the PVQ neurons, we crossed the Puig-1::GFP reporter strain into a PVQ-specific red fluorescent protein (RFP) reporter (Pnpr-11::RFP) strain. We found that Puig-1::GFP is indeed expressed, albeit weakly, in the PVQ neurons.
