TBX-2::GFP expression was present in the both MS- and ABa-derived pharynx cells. TBX-2::GFP expression initiated at the 8E stage (staging by the number of endodermal, or E, cells), in 11 - 12 anteriorly localized pharyngeal cells. Based on position, these cells are likely to be the ABa descendants that will give rise to pharyngeal muscle cells (i.e., ABalpaaa a/p, ABalpapp a/p, ABaraaaaa, ABaraapa a/p, ABarapaa a/p, ARarapapp and ABaraapp a/p). By the 1.5-fold stage, TBX-2::GFP was expressed in pm3, pm5 and variably pm4, with expression persisting throughout the larval and adult stages. Surprisingly, expression extended beyond the ABa lineage after the 1.5-fold stage. For example, only 2/6 pm5 nuclei derive from ABa but authors often observed all pm5 cells expressing TBX-2::GFP in larvae. By the 3-fold stage authors also observed expression in pharyngeal neurons, occasionally in the posterior muscle pm8 and in cells outside of the pharynx such as body wall muscles. Thus, TBX-2::GFP expression initiated within the ABa lineage but ultimately appeared in both ABa and MS-derived muscle cells. |
While TBX-2::GFP was initially localized to nuclei, it was detected in the cytoplasm as well as the nucleus in pm4 and pm5 cells by the 1.5-fold stage. Cytoplasmic expression was not homogeneous. Rather, TBX-2::GFP appeared filamentous, as though it was associated with the cytoskeleton. Cytoplasmic expression was observed even in lines expressing very low levels of TBX-2::GFP, suggesting that cytoplasmic TBX-2::GFP did not reflect over-expression from transgenes. The same pattern was observed in tbx-2(ok529); tbx-2::GFP embryos. This localization pattern suggests that the timing of tbx-2 transcriptional function likely initiates before the 1.5-fold stage, when TBX-2 appears completely nuclear. |

The transgenic strain cop-136(PW08E12.3/4::GFP) was visualized at L4 stage using an inverted fluorescence microscope, which revealed that the expression of W08E12.3/ W08E12.4 is, at large, confined to the pharynx, and in particular pronounced in the dorsal epithelial pm8 cells present above the pharyngeal-intestinal valve. |

pax-1 was expressed in 14 pharyngeal cells, which included nine marginal cells, the e2 epithelial cells and the pm8 muscle, based on morphology, position and co-staining for marginal cell filaments. Expression of pax-1::GFP in marginal cells was first detectable in two rows of pharyngeal nuclei shortly after embryonic cell division ceased, at the late-bean to early-comma stages of development. Expression gradually faded during later embryogenesis and was undetectable in larvae or adult worms. |

This Expr_pattern is about CeTMIV, an isoform of tmy-1 transcription. To confirm the CeTMIV isoform expression pattern, corresponding tmy-1::gfp vectors were assayed. Similar GFP expressions induced in pharynx and intestines respectively. These results show that the CeTMIV isoform was expressed in the pharyngeal muscles and intestinal cells and establish that the primary promoter region was located within 853 bp upstream of the initial ATG. pretzel stage (author) = fully-elongated embryo (wjc). |

The constructs pTMZIV4349 and pTMZIV1957 induced beta-galactosidase expressions in both the pharyngeal muscles and intestinal cells with similar intensities. Specifically, pharyngeal expressions were observed in all the eight muscle cells (m1-m8), one marginal cell (mc), one epithelial cell (e1) and the four cells of the pharyngo-intestinal valve (PIV). The 20 intestinal cells, some of which are binucleated and localized alongside the intestine, posterior of pharynx and anterior of anus were all stained with intense staining occurring at the most posterior end. Intestinal staining was limited only to intestinal cells, although there were slight variations in position of nuclei and staining intensity. Expression was also detected in embryos between gastrulation and the comma stage. At this stage of development, the exact nuclei are difficult to identify, but the positions and topology suggest pharynx and intestines. By the pretzel stage, identification of the different pharyngeal muscles showing expression becomes possible. A similar expression was also observed in the pharynx of males, although the intestinal staining was more restricted to the posterior region. No expression was induced by the further deletion construct pTMZIV1219. In all cases, the most uniform and intense expression patterns were observed between L1 and L2 worms, and were completed by L2. From L3 to adult, there was a reduction in expression intensity. Both pharyngeal and intestinal expressions were evident within six hours after staining. |

Expression becomes detectable around the comma stage of embryogenesis and persists through adulthood. Expression in vulval precursor cells is strong and can first be seen in L3. PQN-47::GFP is expressed in seam cells, peaking at L2 and ceasing after the seam cells differentiate in late L4, concurrent with the appearance of alae. The intestine shows variably undetectable to low pqn-47 expression (always less than in the neurons) and gets dimmer as development progresses, especially after L3. The two bulbs of the pharynx, specifically pharyngeal muscle cells pm3-8 (not pm6), are variably bright. Overall expression levels are lower in adults than younger animals, with only some expression in head and tail neurons remaining. Head and nerve ring neurons, pharyngeal cells, ventral nerve cord cells, vulval precursor cells, seam (though interestingly not hyp7), as well as cells in the tail show the strongest pqn-47 expression. Muscle, intestine, the distal tip cells of the gonad, the spermatheca, and a large neuron that may be CAN that is essential for survival but of unknown function near the vulva (also bathed in pseudocoelom fluid, and next to the seam and canal cells), as well as a subset of the ciliated neurons of the head (amphid neurons ASI, ADL, ASK, or AWB) and tail including phasmid cilia PHA and PHB, also express pqn-47. We could not detect expression in the pharyngeal glands as reported for a different promoter pqn-47 fusion construct made as part of a high-throughput analysis of gene expression, although other tissues did show similar patterns. Promoter and translational reporters show pqn-47 expression in numerous somatic cells, including cells uniquely poised to mediate or transmit signal(s) involved in the regulation of molting, some of which have been implicated in molting. For example, many cells expressing PQN-47 have significant exposure to the pseudocoelom, and as such are candidates to transmit or detect endocrine signals; the H-shaped excretory cell and its ducts, which form extensive gap junctions with the hypodermis and lie against the pseudocoelom along the entire body of the worm (Nelson and Riddle, 1984), the head mesodermal cell (hmc) lies in the pseudocoelom up against the (excretory) gland cell and forms gap junctions with them and muscle, and the VPI cells at the juncture of the pharynx and intestine are bathed by the pseudocoelom, as well as the intestine itself. |

The second component is in the vm2 vulval muscles. The expression here is cytoplasmically localised, and covers only the period around the L4 to adult molt This gene has two distinct modes of expression. The earlier component is in a subset of cells of the pharynx, and is nuclear localised. Expression here is from late embryogenesis onwards, the subset consisting of the m4 muscles in the mid metacorpus,the m2 muscles and e1 and e2 epithelial cells of the procorpus, and the m8 muscle of the posterior terminal bulb. |

The last expression component to appear is in certain cells of the somatic gonad. The D-cells of the vulval labia and unidentified cells of the spermathecal structures begin expression in L4, whilst gonadal morphogenesis is ongoing. The D-cells do not express beyond the first oocyte fertilisations (no zygotes are usually visible when these cells are stained), the spermathecal staining lasting slightly longer into adulthood The next stage at which expression is evident is during the elongation phase of late embryogenesis when the worm is approximately 2 fold. The nuclei of the M2 motor neurones in the terminal bulb of the pharynx stain strongly. More pharyngeal cells show expression as morphogenesis proceeds until at hatching the two I1 interneurones of the metacorpus, either the e2 or m2 cells of the procorpus, and the m8 muscle cell at the pharyngeal-intestinal boundary can all be seen. This pattern remains through the rest of the life cycle, although the m8 expression is lost during early larval stages These early larval stages also see the appearance of expression in the tail region. The nuclei of the anal sphincter cell and 3/4 neuronal cells of the posterior ganglia comprise this regional component of the pattern This gene gives rise to a complicated multicomponent developmental expression pattern. Earliest expression is seen during the cleavage stage of embryogenesis, in the clonal descendants of the E blastomere, the founder cell giving rise the whole of the gut of the adult animal. Expression begins in Ea and Ep just after gastrulation, and continues into each of the granddaughters of these two cells. At this stage, the expressing cells clearly outline the emerging form of the gut. This component ends at about the 150/200 cell stage |

By hatching, its hypodermal expression disappears, while postembryonically born ventral cord motor neurons express it at low levels. Its pharyngeal (strong) and neuronal (faint) expressions continue to adulthood. |

The distribution of signal in transgenic worms was unique and highly restricted with respect to tissue and/or stage of development but did not correspond to the descendants of a particular branch of the cell lineage. Fluorescence was first detectable at the comma stage in cells that divided and appeared to migrate during the 2-fold and 3-fold stages. Neuronal staining was obvious from L1 onward and by early L4 was seen to occur in both the dorsal and ventral nerve chords. During this stage, a strong signal was noted in the developing vulva (most likely the vulE and/or vulF cells). By late L4 an intense GFP signal in the spermathecal valve as well as other vulval and/or uterine structures was evident. Expression in the uv1 and uv2 cells was suggested by the pattern of fluorescence around the vulva. However, the nuclear-localized reporter construct stained more nuclei than can be accounted for by expression in these cells alone. With this construct, nuclear localized signal was observed in all four nuclei of the syncytial spermathecal valve cell. Although GFP fluorescence was seen to be strongest in the late L4 and early adult for the spermathecal valve and vulval/uterine structures previously noted, it was seen to persist throughout adulthood. The M8 cell of the terminal bulb of the pharynx, all six cells of the pharyngeal-intestinal valve, and neuronal cell bodies within the metacorpus and around the isthmus of the pharynx also expressed gly-2p::GFP. At least 37 neurons with cell bodies lying next to the ventral nerve chord were positive for gly-2-directed reporter expression in the adult hermaphrodite, although with widely varying levels of staining. There was also GFP fluorescence present in other neurons associated with the preanal, dorso-rectal, and/or lumbar ganglia. In adult males, expression was similar in non-sexually dimorphic tissues and was also observed in axons that project into rays 2, 3, 5, 6, and either 8 or 9 of the copulatory bursa. |
