89 Expression Patterns

• Primary Identifier: Expr4648
• Pattern: Transgenic lines generated with the full-length protein fusion construct (for example, ljEx114) expressed TRPA-1:: GFP in the same cells as ljEx107 (see Expr4646), but with some additional cells, including the majority of amphid sensory neurons (for example, ASH, AWA, AWB, ASI and ASK) and the phasmid neurons PHA and PHB. The full-length TRPA-1:: GFP fusion was also expressed in the PVD and PDE in the postdeirid sensilla and the sensory neurons OLQ and IL1. Other neurons in the head and ventral nerve cord also expressed TRPA-1:: GFP.
• Subcellular Localization: The fusion protein was observed at the cilia of sensory neurons, as well as at the cell body.

• Primary Identifier: Expr15649

• Primary Identifier: Expr11574
• Pattern: atat-2 is expressed not only in touch receptor neurons but also in a subset of ciliated neurons, namely, PDE, ADE, CEP, and OLQ.

• Primary Identifier: Marker83
• Remark: Picture: Figure 1D and 1H. Reporter gene fusion type not specified.
• Pattern: Marker for OLQ cilia.

• Primary Identifier: Expr11306
• Pattern: Strong expression in young larvae, progressively weaker in older larvae and adults, hypodermis (incl. seam cells), rectal epithelium, pharyngeal muscle (usually very weak), gut, arcade cells, excretory duct and pore cells, OLQs(?)

• Primary Identifier: Expr14514
• Subcellular Localization: Full-length NPHP-2::GFP localized to a short proximal region of amphid channel and phasmid cilia as well as IL, CEP, OLQ, amphid channel and phasmid cilia, and the AWC wing cilia. Native promoter driven NPHP-2::GFP was not visible in AWB cilia, as reported previously for AWB- specific promoter driven NPHP-2. We conclude that NPHP-2 marks a region of the cilium distinct from the doublet region, and propose that this region is analogous to the InvC of mammalian cilia.

• Primary Identifier: Expr3037
• Pattern: The 5' untranslated region directed expression to a small subset of sensory cells that are ciliated. GFP signal was observed in the multiple ciliated amphid neurons in the head and both ciliated phasmid neurons (PHA and PHB) in the tail. Expression was also detected in other ciliated sensory neurons, including the inner and outer labial neurons and male tail ray neurons. GFP fluorescence was also detected in the midbody PDE ciliated neuron and PQR ciliated tail neuron.

• Primary Identifier: Expr3185

• 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.

• 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: Expr15611

• Primary Identifier: Expr716
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
• Pattern: Expression observed in most or all neurons at high levels as well as in some hypodermal and muscle cells. In most neurons, sax-3::GFP expression is transient, peaking during the period of axon outgrowth. Highest level of expression is observed in the embryo, particularly during the initial period of axon outgrowth at 350-400 min (comma-stage). At comma-stage high level of expression is observed in anterior embryo, including most developing neurons of the nerve ring and a swath of ventral cells that includes the developing motor neurons of the ventral nerve cord and posterior neurons such as PVQ. Lower level of expression is observed in the epidermal cells. 200-400 - cell stage; 200-300 min of development: Expression seen in all epidermal cells at low level. 3-fold stage; >500 min of development: Expression seen in muscles that extend from nerve ring to the anterior tip of the head. L1: Expression in motor neurons in the head including RMD, RMG, SMD, SIA and SIB neurons; projection interneurons in the head and tail, including AVA, AVB, PVC, AVD, PVQ and ALA neurons; and the sensory OLQ neuron. This neuronal expression diminishes throughout postembryonic development. During L1, expression persists in the head muscles and appears in muscles along the body wall, with ventral muscles expressing more strongly than posterior muscles. This expression continues until the adult stage. Epidermal expression was rarely seen in larval stages. L2: Expression observed in HSN motor neurons. HSN motor neurons extends a growth cone (axon from their lateral cell bodies) towards the ventral midline and expression is at its highest at this point. L3: Expression observed in the axon reaching the ventral nerve cord. L4: Expression continues in HSN, when HSN axon grows anteriorly to the head. Adult: Expression decreases in HSN at this stage after the completion of HSN axon outgrowth. In addition expression observed in motor neurons, interneurons and sensory neurons listed above also postembryonic ventral cord motorneurons, some interneurons from the tail and head, body wall and vulval muscles.

• Pattern: dyrb-1::GFP is expressed in phasmid and OLQ neurons. Is also expressed in IL-type CSN (head), phasmid CSN (tail), intestine, unidentified neurons posterior to the nerve ring (non CSN).

• Primary Identifier: Expr976
• Remark: Reporter gene fusion type not specified. The antibody staining showed EAT-20 expression in the seam cells and hypodermal cells, which is inconsistent with the absence of GFP expression in those cells in the promoter trap lines, suggesting that p5E5 may not contain all the cis-regulatory elements necessary for the expression of the eat-20 gene.
• Reporter Gene: GFP expression was analyzed in ncIs1 hermaphrodites carrying p5E5 as a stable integrated transgenic array. Though p5E5 contains a 2-kb genomic fragment derived from LGV at the 5' side in addition to the fragment corresponding to the eat-20 gene, it is confirmed that an extrachromosomal array of p5E5 and that of p5E5del, in which the 2-kb fragment was deleted, gave the same GFP expression pattern. Thus, the fragment at the 5' part of the insert had no effects on the expression of GFP. Neurons expressing GFP were first identified in L1 larvae.
• Pattern: In embryos, GFP expression was first detected at the 2-fold stage. Sometimes eight cells in the anterior half of the body expressed GFP. At the 3-fold stage, several cells around the pharynx expressed GFP in most embryos. About half of the embryos also expressed GFP weakly in the pharynx. At L1, GFP was detected in a subset of neurons. About half of the larvae also expressed GFP in the pharynx; expression in the terminal bulb was the most intense. At the adult stage, GFP was detected in the pharyngeal muscles, m3, m4, and m6. In addition, GFP was detected in a subset of neurons: IL1, OLQ, BAG, and ALN, several circumpharyngeal cells, and coelomocytes. Very faint GFP fluorescence was detected in the pharyngeal neurons including I4 and I5 in L1 larvae.

• 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.
