• Primary Identifier: Expr4281
• Reporter Gene: [wrk-1::TM-gfp] translational fusion. wrk-1 expression was determined by means of a reporter construct (wrk1::TM::gfp), in which 4 kb of sequences upstream of the ATG start codon, all exons, and the first three introns of the wrk-1 locus were fused in frame to gfp. This construct is able to rescue the phenotype of wrk-1 mutant animals. See Transgene otEx2389. [wrk-1::gfp] transcriptional fusion in which 4 kb of sequences upstream of the ATG start codon was fused to GFP. See Transgene otEx203 [wrk-1::gfp] translational fusion. See Transgene otEx2522.
• Pattern: The wrk-1 gene is expressed in ventral midline cells, namely in the eMNs. Additional expression is observed in a subset of head neurons, including interneurons (AIY class), sensory neurons (ASI class), and head motoneurons (SMDV/D class), and glial-type sheath and socket cells. Outside the nervous system, the most prominent sites of wrk-1 expression include the intestine, excretory gland cell, distal tip cell, and coelomocytes.

• Pattern: The transcriptional reporter of gbb-1 was expressed in a number of head neurons, including SMD.

• Primary Identifier: Expr9910
• Pattern: While DMA-1::GFP is dominantly expressed in PVD and FLP, especially by the adult stage, DMA-1::GFP expression in additional head and ventral cord neurons was detected during larval and early adult stages. DMA-1 expression was detected in the PVD cell body shortly after PVD are born (L2 larval stage) before any dendrite outgrowth or branching has occurred. Weaker DMA-1::GFP expression can be seen in ventral cord motorneurons and in the sub-lateral cords.Expression was variable from animal to animal, seen in both commissural and non-commissural motorneurons, and was mostly undetectable by the early adult stage. In the head, expression of DMA-1::GFP was detected during development in additional head neurons besides FLP. Of these neurons, the strongest expression was detected in neurons that run around the nerve ring and extend processes along the sub-lateral cords (likely some combinationof the SIA, SIB, SMB and/or SMD classes of neurons). A number of additional head neurons displayed inconsistent DMA-1::GFP expression from animal to animal. Again, expression in these additional neurons was transient and mostly undetectable by the early adult stage. d, Strong expression DMA-1::GFP was detected in vulva cells during the L3-L4 larval stages.
• Subcellular Localization: Bright DMA-1::GFP localization can be seen in intracellular membrane structures that are likely to be golgi/ER. The plasma membrane is also clearly visible, indicating that DMA-1::GFP is a cell-surface protein.

• Pattern: 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).

• Pattern: 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.
