125 Expression Patterns

• Primary Identifier: Expr4859
• Pattern: A-class motor neuron: enriched in embryo (8.7) and larva (7.9). Neuronal expression include: I5, ASE, ASG, BAG, DD, M3, M5, head neurons. Pan-neuronal: expressed in embryo; enriched in larva (7.1).

• Primary Identifier: Expr4684
• Pattern: GFP expression was detected at most developmental stages, with the spatial expression depending on the developmental stage of the animal. Neuronal expression of hlh-29 was detected in larvae and adults in both amphid and phasmid sockets, in the ALA and PVT neurons, in the chemosensory and mechanosensory neurons, ASI, ASK, PHA, and PQR, and in neurons of the anterior pharyngeal bulb. Weaker expression was also detected in the ASG chemosensory neurons in some transgenic lines. L1 animals show strong expression of hlh-29 in intestinal cells, and weaker expression in the rectal glands and the pharyngeal muscle cell PM1. By L3 stage, intestinal expression of the hlh-29::GFP is limited to the posterior intestinal cells, and PM1 expression is no longer detected. Expression is also detected in the ventral posterior coelomocytes in the later L3-stage larvae, and in the spermatheca and vulval muscles of L4 and adult animals.

• Primary Identifier: Expr4985
• Remark: Picture: Fig 5.
• Pattern: GFP expression was specifically localized to a few cells at the anterior and posterior regions of the worm. At the anterior region, the GFP expression was identified in two amphid neurons (ASG), the pharyngeal intestinal (PI) valve (six cells), one to two neurons in retrovesicular ganglion (RVG), and two neurons posterior to the PI valve. The GFP expression in the posterior region was localized to the two phasmid neurons (PHA, PHB) and the anal valve (four cells). The results indicated that the promoter of CEFT-1 is specifically activated in chemosensory neurons (amphids and phasmid neurons) and valve regions (PI valve and anal valve). Promoter expression was evident through all developmental stages with a highly restricted GFP expression.

• Primary Identifier: Expr4533
• Pattern: Expressed in ASGL/R (faint).

• Primary Identifier: Expr4538
• Pattern: Expressed in ASGL/R, ADLL/R (faint).

• Primary Identifier: Expr11200
• Remark: Reporter fusion construct for the translational fusion not specified.
• Pattern: Upstream regulatory sequences of cng-2 drove gfp expression exclusively in six pairs of head sensory neurons in the adult. AWC, ASE, ASG, ASI, ASJ, ASK (Fig. 2B).
• Subcellular Localization: When expressed under an ASK-specific promoter the CNG-2 fusion protein was restricted to the ASK cell bodies.

• Primary Identifier: Expr15649

• Primary Identifier: Expr16432
• Pattern: We detected DMD-9::GFP expression in 10 head neurons of hermaphrodites at the L4 stage. High dmd-9 expression was detected in the BAG, AFD, AWCon, AWCoff, ASEL, and AWB neurons, with lower expression in ASER, and the ASGs. We also observed weak and inconsistent expression in other head neurons and transient weak expression in the tail of hermaphrodites and males at the L4 stage. No overt differences were observed in DMD-9::GFP expression in neurons of hermaphrodites and males. We also detected DMD-9::GFP expression in non-neuronal tissues. Transient DMD-9::GFP expression was observed in the uterine cells at specific sub-stages of the L4 stage. DMD-9 is not expressed from L4.0 to L4.3, with expression first detected in the early L4.4 stage, with the highest level during L4.4. before gradual loss by the L4.9 stage (Mok et al. 2015). DMD-9::GFP was not detected in adult uterine cells. We also detected DMD-9::GFP expression in sperm of hermaphrodites and males. In addition, we found that in a small proportion of L4 animals DMD-9::GFP shows asymmetric expression in the ASEs and AWCs neurons.

• Primary Identifier: Expr3175
• Pattern: Expressed in ADF, ADL, AFD, ASE, ASG, ASH, ASI, ASJ, ASK, AWA, AWB, AWC, BAG, PHA, PHB, URX, intestine.

• Primary Identifier: Expr8976
• Remark: Picture: Fig 4E to 4H. npr-5 = Y58G8A.4 in this paper.
• Pattern: The npr-5p::RFP transgene was expressed in a subset of amphid neurons (ADF, ASE, ASG, ASI, ASJ, ASK, AWA, AWB) in the inner labial neuron IL2, in the interneurons AIA and AUA, and in the phasmids (PHA, PHB). Outside the nervous system, npr-5p::RFP was expressed in head, neck, and body muscles throughout larval and adult development.

• Primary Identifier: Expr11753
• Remark: genomic

• Primary Identifier: Expr15085
• Pattern: Using a bicistronic GFP reporter transgene, we found that capa-1 is expressed in a single pair of chemosensory neurons. Co-localization of GFP with mCherry, expressed from the ASG-specific gcy-15 promoter, identified these cells as ASG.

• Primary Identifier: Expr3185

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