• 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).

• Remark: Cells expressing TAX-6 were visualized using several tax-6::gfp fusion genes. The expression of tax-6 is under diverse transcriptional controls. Reporter gene fusion type not specified. pAK43 is a larger transgene that should include all promoter regions for tax-6 transcription, since another gene is encoded just upstream of this region and tax-6 mRNA does not seem to be derived from a polycistronic transcript.
• Pattern: When introduced into wildtype animals, pAK43 drove TAX-6 expression in many sensory neurons, as well as interneurons including AIY and AIZ, and most, if not all, muscle cells. pAK43 is expressed in muscle, AIB, AIY, AIZ, RIA, RIB, RIS, RIM, ASI, ADF, ASH, ASK, ADL, AUA, PHA, PHB, AVE. It is also expressed in AFD, ASE, AWA, AWC, AVK, AIM, RMDV, AVA.

• Primary Identifier: Expr15194
• Pattern: We consistently observed aat-1::mCherry fluorescence in several pairs of head neurons; pharynx; reproductive system -including vulval muscles, uterine muscles, and uterine-vulva cells; excretory cells; and weak transgene expression in the intestine of adult animals. Reporter fusions controlled by the aat-1 and nkat-1 promoters showed overlapping expression patterns in RMDV and RIM neurons

• Primary Identifier: Expr3310
• Pattern: Expression was detected first in neuronal precursor cells at the comma stage. Slightly later strong expression was found in the hypodermal cells. In newly hatched L1 larvae this construct continued to be expressed in neuronal cells in the head and tail, in cells of the ventral nerve cord and of the pharynx. During the early L1 stage hypodermal expression disappeared. The GFP-positive neurons in animals carrying pT14G10.2::GFP-II were identified as the RMDD, RMD, RMDV, SMDD, and SMDV, which are ring motoneurons. Also the more posteriorly located BDU cells and the ALN, PVR, and PVT cells in the tail expressed GFP. Analysis of synchronized worms showed that GFP is present around the time of molting, but is barely detectable during part of the intermolts or in adults. During the outgrowth of the gonadal primordium expression was seen in the distal tip cell and oviduct sheath cells.

• Remark: Picture: Figure 2, Fig. S2BE.
• Pattern: The expression of genomic magi-1::gfp and magi-1::rfp chimeric transgenes, which contain 4 kb of upstream sequence and either the complete magi-1 ORF or only the genomic magi-1 long isoform sequences, yielded similar results The magi-1L:::gfp reporter transgene reflects the expression of the long isoform. Expression of MAGI-1L::GFP was detected in the pharynx, head neurons, ventral cord, and vulva of animals mosaic for the extrachromosomal array. Expression of MAGI-1L::RFP was also detected in the pharynx, intestine, vulval epithelia (L4 stage), and vulval muscle (adult stage) of animals mosaic for the extrachromosomal array. This antibody labeled both neurons and epithelial junctions in immunofluorescence experiments. Within the hypodermis and intestine, there was a high degree of colocalization between MAGI-1 and DLG-1. The anus and vulva also were labeled in larval and adult animals. Finally, MAGI-1 expression was observed in some neurons in the head, including a subset of the GLR-1::GFP-expressing command interneurons. MAGI-1 is expressed in the backward but not the forward command interneurons; MAGI-1 expression was not detected in any of the mechanosensory neurons. MAGI-1 was detected in the neurons AVA, AVD, and SMD, as well as RMD and RMDV.
• Subcellular Localization: Anti-MAGI-1 antibody detected MAGI-1 localization to puncta along the ventral cord; however, MAGI-1 is expressed in more neurons than just those that express GLR-1, making analysis of colocalization in the ventral cord difficult. To help restrict the analysis to the GLR-1-expressing neurons, both MAGI-1 isoforms were expressed as mRFP chimeric proteins under the glr-1 promoter; both substantially colocalized with GLR-1.

• Primary Identifier: Expr7866
• Remark: Picture: Figure 5A to 5E.
• Pattern: This UNC-36::GFP reporter was expressed in most neurons and virtually all muscle tissue (consistently in body wall and vulval muscle, and sometimes in the pharyngeal muscle). Expression of the UNC-36 reporter was observed in mechanosensory neurons, as well as a number of additional unidentified neurons in the head and tail. GFP expression was observed in ALM, AVM, BDU, and SDQR. Also identified in the tail neurons PVQ, PVC, DVC, and DVA. PLM, ALN, and PHB were probable, but not certain. In the head GFP was expressed in ASE, AVA, SIBDL, RMDVL, ASK, and a number of unidentified neurons. Expression was also observed in PVM and SDQL.

• Remark: Neuronal gene expression pattern from collation by Shawn Lockery of neuron-specific promotors posted 20/04/98 (http://chinook.uoregon.edu). Since cell AS is listed under 'body' in the pattern, it presumably means the AS.1-11 ventral cord neurons rather than the AS amphid neurons.[sdm-curator]

• Remark: Since these gfp fusions lack the introns and the 3' untranslated region, they might be lacking potential regulatory sequences. In that case, the gfp expression patterns may not precisely represent those of the endogenous kin-8 gene. cam-1 is called kin-8 in this article.
• Pattern: Expressed in chemosensory neurons in amphid: ASH. Other sensory neurons: ADE, FLP. Touch receptor neurons: AVM, ALM, PVM, PLM. Amphid interneurons: AIY, AIZ. Other interneurons: RIC, RMG, RIS, DVA, AVA, AVE, PVC, AVK, PVQ. Interneurons?: ALN, BDU, SDQ. Ring motor/inter neurons: RMD, RMDV. Ring motor neurons: RMED, RMEV Five neurons out of the following six, RIV, AVH, AVB, AVJ, AVD, AIN. About seven neurons in retrovesicular ganglion. Pharyngeal muscles in procorpus and isthmus. M4 and several pharyngeal neurons. A part of intestine and a few body wall muscles near the head (weak). Distal tip cells (sometimes and weak). A few ventral motor neurons and seam cells (rarely and weak). The expression patterns did not appear to change through the larva to adult stages. Embryonic expression was also observed.
