A GFP reporter transgene with 5.8 kb of the nsy-5 promoter was expressed exclusively in sensory neurons and interneurons in the head and tail. The neurons that expressed nsy-5::GFP included AWC, ASH, AFD, ASI, ADL, ASK, BAG, AWB, and ADF (head sensory neurons); ADA, AIZ, RIC, AIY, and AIM (head interneurons); PHA and PHB (tail sensory neurons); and PVC and PVQ (tail interneurons). Expression began about halfway through embryogenesis, was strongest in late embryogenesis and the L1 larval stage, and faded thereafter. Adults maintained weak expression in several neurons, including ASH but not AWC. |

ceGAT-1 is expressed in all of the GABA-ergic neurons. These GFP-positive neurons include the VD and DD neurons in the ventral cord, the RMED, RMEV, RMEL, RMER, AVL, and RIS neurons in the head area and the DVB neuron in the tail region. There are two additional GFP-positive neurons in the tail region. These two neurons are PVQR and PVQL. The identity of these GFP-positive neurons were confirmed by epifluorescence microscopy and by the location of the neurons as revealed by a combination of Nomarski-differential interference contrast microscopic observation and 4',6-diamidino-2-phenylindole nuclei-staining method. This expression pattern is evident from the early larva stage through the adult stage. An identical expression pattern was observed with at least 10 transgenic animals. |

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. |

asic-1 is expressed in eight neurons comprising the C. elegans dopaminergic system (the four cephalic neurons; two anterior deirid neurons and two posterior deirid neurons; CEP, ADE, PDE, respectively). Expression is also detected in four additional neurons in the tail, two of which are the bilaterally symmetric PVQ interneurons. |
A full-length ASIC-1::GFP and an amino-terminal ASIC-1N::GFP chimaeras showed prominent punctuate distribution along the processes of dopaminergic neurons, in synapse-rich areas. A DsRED-synaptobrevin fusion colocalizes with both ASIC- 1::GFP and ASIC-1N::GFP in these puncta. Thus, ASIC-1 localizes at presynaptic termini of dopaminergic neurons. |

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. |

cam-1 is broadly expressed in many cell types, including muscle, hypodermis, and neurons (Forrester et al. 1999), making direct identification of relevant cells difficult. To determine whether cam-1 is expressed in PVP and PVQ neurons, the Pcam-1::cam-1::GFP strain was crossed with hdIs26[Podr-2::CFP; Psra-6::dsRed2], which expresses CFP in PVP and dsRed in PVQ. Strong CAM-1 expression was observed in PVQ but only weak expression in PVP. CAM-1 is also expressed in PVT. |

The timing expression pattern of coq-8 gene reported herein correlates with the overall Q content in C. elegans. Higher expression of coq-8 gene, and presumably Q biosynthesis activity, correspond with those tissues with particularly active bioenergetics in different development stages during life cycle. Thus coq-8 expression pattern may directly or indirectly reflect bioenergetics and cellular activity in vivo. |

As adult animals progressed towards the post-fertile period, COQ-8::GFP expression became restricted to nervous system, whilst in other tissues, including muscles, progressively diminished until it completely disappeared. During the adult stage stained neurons could be individually identified. These included at least the ASIL, ASIR, PHAL, PHAR, PVDR and PVDL sensory neurons. The interneurons AVKL, AVKR, PVT, PVQL, PVQR, and motoneurons AS1 to AS8, DA1 to DA9, DD1 to DD6, and VC1 to VC6, were also stained. COQ-8 expression in hypodermis was not evident until worms reached the L2 stage, however not all hypodermal cells showed similar expression levels. Lateral hypodermal syncytium appeared heavily stained whereas seam cells, that form a protruding hypodermal ridge termed alae, did not show significant fluorescence. Neuronal cells stained in L1 remained stained during L2 stage. COQ-8 expression pattern changed in L4 larvae and young adult stages of very active and fertile young individuals. Hypodermis fluorescence decreased abruptly and GFP signal appeared restricted to muscles and nervous system. It worth noting that hypodermal COQ-8::GFP expression was readily observed during moulting period but decreases abruptly in young adults, that no further moults, allowing the detection of COQ-8::GFP fluorescence in smaller cells as coelomocytes, which were not readily visible in earlier larval stages. Coelomocytes are defensive phagocytes that produce reactive oxygen species (ROS) in worms and other invertebrates and a high Q content would be needed to prevent oxidative damage derived from this particular oxygen metabolism. During egg development fluorescence was readily detectable in early pre-morphogenetic stages about 4 to 5 h post-fertilization, becoming higher in both intensity and number of fluorescent cells during later embryogenesis. 4D microscopy revealed some spatial and temporal variability in the initial expression of COQ-8::GFP from embryo to embryo. The beginning of the COQ-8::GFP expression was detected between the 8th and the 10th embryonic mitosis and was triggered by a group of several blastomeres in all the analyzed embryos. These blastomers are committed to differentiate into specific tissues with high energetic requirements, such as neurons and muscles, but also hypodermis and coelomocytes. These tissues also showed fluorescence during later life stages. Fluorescence reached its maximum intensity in L3 stage of development, supporting a genetic basis to previous observations that showed highest Q content in L2 ~ L4 stages. Longitudinal nervous ventral and dorsal cords showed high fluorescence and some muscular innervations were also stained at this stage. Expression of COQ-8::GFP was clearly evident in hypodermis, neurons and cords, and muscle cells. This expression pattern cannot exclude other tissues showing much weaker fluorescence that may not be readily observed. The expression in muscle and neuronal cells was detected during larval development as early as in the first larval stage (L1). At this stage, longitudinal muscles quadrants were GFP-stained tail and pharyngeal ring neural centres displayed significantly higher COQ-8 expression levels than other tissues. The nervous system of L1 wild type larvae is not entirely developed and contains fewer connections between neurons than in older animals, as it is observed by the GFP staining. |

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. |
