92 Expression Patterns

• Primary Identifier: Expr16352
• Pattern: We confirmed previous reports that the asic-1 promoter drives expression in the ADE, CEP, PVQ, PDE and PVD neurons (De Stasio et al., 2018; Husson et al., 2012; Voglis & Tavernarakis, 2008) and also observed expression in FLP and ventral cord neurons.

• Primary Identifier: Expr11819
• Pattern: Evidence of ASIC-1 expression was found in FLP neurons, but not in PVD neurons, because an asic-1 promoter drove expression of the fluorophore mCherry in this neuron pair. Pasic-1::mCherry expression was also found in other neurons, including the mechanosensitive dopaminergic sensory neurons previously reported to express asic-1.

• Primary Identifier: Expr15649

• Primary Identifier: Expr13955
• Pattern: dma-1, bicd-1, and flp-4 were expressed in FLP and PVD neurons.

• Primary Identifier: Expr15284
• Pattern: We observed prominent dma-1p::dma-1::gfp expression in the IL2 dendrites during dauer. Expression of dma- 1p::dma-1::gfp was not detectable in adult IL2s. dma-1p::dma-1::gfp translational reporter is prominently expressed in the FLPs and PVDs during dauer. We observed prominent dma-1p::dma-1::gfp expression in the IL2 dendrites during dauer. Expression of dma- 1p::dma-1::gfp was not detectable in adult IL2s.

• 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: eat-4 is expressed in 78 of the 302 neurons of the adult hermaphrodite, which fall into 38 neuron classes (out of a total of 118 anatomically defined neuron classes in the hermaphrodite). Most of these neurons are either sensory- or interneurons. Only two motorneurons utilize glutamate; both are located in the pharynx.

• Primary Identifier: Expr733
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
• Pattern: Staining is seen in a set of 47 nuclei in fixed newly hatched first larval stage (L1). All stained cells are neurons. Hermaphrodite express in cells. RIH, RIR, PVR, IL2L/R, URYVL/R, RIPL/R, AIZL/R, FLPL/R, ADAL/R, RMGL/R, BPUL/R, PLML/R, ALML/R, ALNL/R, HSNL/R, URBL/R, NSML/R, URADL/R, IL2DL/R, I2L/R, IL2VL/R, URAVL/R, URXL/R, AIML/R, URYDL/R, PQR, PVM, SDQL/R, PVDL/R, PHCL/R, PLNL/R. Male cells express as in hermaphrodite except for HSNL/R which die, and show expression in CEMDL/R, CEMVL/R which die in hermaphrodites. Expression pattern is first determined in the Q lineage. Once expression has been initiated in a cell, it is maintained by that cell and all of its descendants in all cases except for SDQ.

• Primary Identifier: Expr13698
• Pattern: The expression of npr-12 was confirmed in PVD neurons, including the cell body, dendrites, and axons, using npr-12 transcriptional and translational reporter strains (Pnpr-12::GFP, Pnpr-12::NPR- 12::GFP). npr-12 is expressed in neurons other than PVD as well, such as the epidermis-associated head sensory FLP neurons.

• Primary Identifier: Expr3222
• Remark: Reporter gene fusion type not specified.
• Pattern: Epidermis: ncr-1Ap(l)::gfp was strongly expressed in the excretory cell and rectal epithelial cells from the early L1 larval stage and through all life stages. Seam cell expression was first observed in the late L1 stage, while expression in the lateral hypodermis increased during the L3 stage and peaked during the L4 stage. Seam cell and hypodermal expression gradually decreased in the adult stage and was hardly visible among older adults. ncr-1Ap(s)::gfp was not expressed in the hypodermis under normal growth conditions, though lateral hypodermal but not seam cell expression was dramatically upregulated in starved animals of all developmental stages. No increase in hypodermal expression was seen in starved ncr-1Ap(l)::gfp animals. Intestine: Both ncr-1Ap(s)::gfp and ncr-1Ap(l)::gfp were strongly expressed throughout the intestine, with posterior intestinal expression consistently stronger than anterior expression. Musculature: ncr-1Ap(l)::gfp was strongly expressed in pharyngeal muscles, but not in body wall muscles. Nervous system: ncr-1Ap(s)::gfp and ncr-1Ap(l)::gfp were expressed in the same set of head and tail neurons and a pair of neuron-like cells identified as the XXX cells. According to their location and cellular morphology, the head neurons were identified as the pharyngeal neuron I6, the inner labial sensory neurons IL2s and the amphid neurons ASE and ASG. The expression level in the amphid neurons was weaker than in the other head neurons. The tail neurons were identified as PHC, in which expression was first detected during the L2 stage, consistent with the time of birth of the neurons at the end of L1. In contrast to the widespread expression of ncr-1Ap::gfp, ncr-1Bp::gfp is expressed exclusively in 10-12 pairs of head and tail neurons. The tail neurons were identified as PHA, PHB and DVC. One pair of head neurons was identified as AWC. The other head neurons were very tentatively identified as RIC, RIM, FLP, ADA, ADE, RID and maybe AIY. We also occasionally observed expression in a pair of head cells anterior to the nerve ring. The position and morphology of these cells are similar to the XXX cells. With the exception of PHC neurons, expression in the tissues above was first observed during late embryogenesis and did not change during development. Somatic gonad: Both ncr-1Ap(s)::gfp and ncr-1Ap(l)::gfp were strongly expressed in the spermatheca and weakly in the gonadal sheath cells. The expression in the somatic gonad could be observed only in adults. Three reporter constructs, ncr-1Ap(s)::gfp, ncr-1Ap(l)::gfp and ncr-1Bp::gfp were made for ncr-1 because of its complex gene structure. The results indicate that ncr-1 expression is widespread and largely coincides with the reported distribution pattern of cholesterol in C. elegans, which includes the following tissues: intestine, pharynx, excretory gland cell, nerve ring, spermatheca and germ cells, including both oocytes and sperm.

• Primary Identifier: Expr1261
• Pattern: Expressed in a subset of neurons in the pharynx and in the extrapharyngeal nervous system. Expression was also noticed in intestine cells(int1-int9). In the pharynx, eat-4 was found to be expressed in M3, NSM neurons, and possibly I5, but not in muscle. Clear and consistent eat-4 reporter expression was found in 15 different anatomical types. ADA, ALM, ASH, ASK, AUA, and AVJ or AIN, AVM, FLP, IL1, LUA, OLL, OLQ, PLM, PVD, and PVR.

• Primary Identifier: Expr13958
• Pattern: egl-44 expression was much more restricted then zag-1, being found only in the FLP, ADL, and SAB neurons, as well as a few VA and VB motor neurons. Moreover, egl-44 was widely expressed in hypodermis, pharynx, and intestine, whereas zag-1 expression was absent in these tissues.

• Primary Identifier: Expr11196
• Pattern: phpo-30::GFP is highly expressed in PVD. In addition to expression in PVD, the hpo-30::GFP reporter was also detected in the FLP neuron and in a subset of additional head and tail neurons and in the ventral nerve cord. hpo-30::GFP was not detected in touch neurons.
