The nhr-239::gfp reporter was weakly expressed in three to four pairs of neurons in the head and a pharyngeal neuron in late stage embryos and all larval and adult stages. One pair of dorsal neurons express nhr-239::gfp very consistently and appear to be sensory, as do one pair of pharyngeal cells that appear to be the MC, NSM or M3 neurons.Faint fluorescence was observed in the pharynx (which may be an artefact), but did not observe nhr-239 expression in other cells at any stage. As expected from the modest expression levels observed in qRT-PCR experiments, fluorescence from the nhr-239::gfp transgene was very faint. While it is possible that the translational fusion did not recapitulate the entire nhr-239 expression pattern, this result suggests that nhr-239 is expressed only in a very limited subset of neurons. nhr-239 transcripts were identified by real-time qRT-PCR at very low levels (no more than 2x10-6 the level of 18 S rRNA standards) and displayed a more complicated pattern, increasing somewhat from embryos to L1, before declining progressively during later larval development. |

Synaptogyrin is expressed in all 26 GABAergic neurons including also RMER and most though not all other neurons. Synaptogyrin is absent in amphids and phasmids and can be detected in non-neuronal glial-like sheath cells in adult worms. The cephalic neurons CEPDR/L and CEPVR/L and amphid-associated sheath cells CEPshDR/L, CEPshVR/L were tentatively positive. Several other neurons that could be tentatively identified in the anterior part are MI, M4, I4, AVL, AIY, RIS, I5, M3R/L, and in the posterior part DVA, AS11, ALNR/L, DVC, DVB, PQR, DA9 (characteristic axonal process denoted by arrowhead), VD13, DD6, VD12. Of these, AVL, RIS, VD13, DD6 and VD12 are GABAergic based on the colocalization with the unc-47p::GFP reporter. In addition, IL neurons were tentatively identified in the anterior (IL*). Synaptogyrin reporter constructs are also expressed in developing neurons. The expression of sng-1p::YFP is closely associated with the development of the nervous system being absent in the gastrula stage with first fluorescence in neuronal precursor cells and newly-formed neurons in the anterior part during the 1.5-fold stage. In addition, it is also detected transiently in cells in the posterior body at the 1.25-fold and 1.5-fold stage. |

The cellular expression pattern for nlp-3 fragments was indistinguishable from the cellular expression pattern for nlp-3 subcloned constructs. Transgenic lines were generated by coinjection of the nlp::gfp construct (5070 ng/ul) and lin-15 rescue construct (pJM24,100 ng/ul) into lin-15(n765ts) animals. At least two independent transgenic lines were analyzed for each nlp gene; 5-10 animals were scored per line. 1,1'-Dioctadecyl-3,3,3',3 -tetramethylindodicarbocyanine perchlorate (Molecular Probes) was used to stain amphid and phasmid neurons to facilitate identification. |

acc-1 and acc-2 fosmid reporters show very restricted and non-overlapping expression in the adult nervous system. The acc-1 fosmid reporter is expressed in a subset of cholinergic neurons, including cholinergic neurons in the ventral nerve cord, the retrovesicular ganglion and a few head neurons (including the SMD, RMD motor neurons, the AVA and AVE command interneurons and the SAA neurons). A small number of glutamatergic neurons also express acc-1 (including the pharyngeal neurons MI and M3, the PLM neurons and an unidentified neuronal pair in the lateral ganglion). |

Expression of ceh-34::gfp transgene began during embryogenesis. CEH-34::GFP was localized to the nuclei of expressing cells. During embryonic morphogenesis and larval development and throughout adulthood, expression of the ceh-34::gfp transgene was seen predominantly in pharyngeal cells. The ceh-34::gfp transgene was expressed in all pharyngeal neurons (M4, I1, MI, I3, M3, NSM, MC, I2, I4, I5, I6, M1, M2, and M5), some pharyngeal muscle cells (pm1 and pm2) and pharyngeal epithelial cells (e1 and e3), and some body wall muscles around the anterior pharynx. |

Embryonic expression of exc-7 was first observed at the bean stage. By reverse lineaging with use of SIMI-Biocell software, we confirm the identity of one of the expressing cells at this stage as the excretory canal cell. In L1 animals, broad expression in the head, ventral nerve cord (VNC), and tail was observed. In young adults, expression is notably observed in vulva cells. In the nervous system specifically, expression is observed in many neurons throughout the body, but unlike Drosophila Elav, exc-7::gfp it is not panneuronally expressed. We confirmed previously reported expression in cholinergic VNC MNs, but absence of GABAergic VNC MNs, consistent with previous reports (Fujita et al., 1999; Loria et al., 2003) and consistent with exc-7 functioning in cholinergic, but not GABAergic neurons to control alternative splicing (Norris et al., 2014). exc-7::gfp is also expressed in some non-neuronal cell types, including muscle and hypodermis, but not in the gut. A previous report showed that exc-7 is only transiently and weakly expressed in the excretory cell, which, based on exc-7's excretory mutant phenotype, has puzzled researchers (Fujita et al., 2003). We find that the gfp tagged exc-7 locus is strongly and continuously expressed in the excretory canal cell. |

Most of these neurons are either sensory- or interneurons. Only two motorneurons utilize glutamate; both are located in the pharynx. |
