• Pattern: unc-103::GFP construct expressed broadly in the head and ventral cord neurons in both males and hermaphrodites. In the male tail the SPC motor neurons and the PCB postcloacal sensory neurons expressed the construct. Many neurons express the construct, but because of variability in cell position and cellular localization of the fusion protein in processes, the list of unc-103-expressing cells is far from complete. In the head region ALA, ADL, ASK, AVH, AVJ, AIN, AVA, ASJ, SMDD, SIA, ADE, and AVD express the construct. In the tail region PHA, DVC, ALN, and PVP express the construct. The unc-103 fusion protein accumulates extensively in the processes of many ventral cord neurons; however, only some cells in the AS class of excitatory neurons was identified. In the adult hermaphrodite HSN expresses the unc-103::gfp construct.
• Subcellular Localization: The fusion protein aggregates mostly on the cytoplasmic membrane of neuronal processes and in many, but not all, cases of cell bodies. In larval hermaphrodites and males some of the cells had cell body localization of UNC-103::GFP.

• Primary Identifier: Expr8296
• Remark: Picture: Fig. 3C,D.
• Pattern: Expressed in the SPC motor neurons, PCB and PCA postcloacal sensilla (p.c.s.) neurons, male spicule protractor muscles and anal depressor muscle, VD and DD ventral cord neurons, some tail and nerve ring neurons, and body wall muscles. In hermaphrodites, YFP expression is in the same set of cells, except those specific to males.

• Primary Identifier: Expr9999
• Pattern: A 2.8 kb promoter of cysl-1 drove GFP expression mainly in the nervous system of adult hermaphrodites. The cysl-1::GFP expression pattern was similar for the transcriptional and translational reporters. GFP was observed in subsets of pharyngeal neurons, amphid sensory neurons and tail neurons, starting from late embryonic stages and persisting into adults. We identified GFP-positive cells as the AVM sensory neuron, the BDU interneurons, and the pharyngeal I1 interneurons and M2 motor neurons, based on their characteristic processes and nuclear positions. GFP in body wall muscles, hypoderm, and intestine was present in larvae but only weakly detectable in adult animals.

• Primary Identifier: Expr12313
• Pattern: In these transgenic males, UNC-7 expression was found, in addition to the sex muscles (Expr12312), in several mating circuit neurons (SPC, PCA, PCB, HOA, and unidentified ray neurons). Similar to previous studies (Starich et al., 2009; Yeh et al., 2009; Kawano et al., 2011), this reporter also expresses in head ganglion neurons, several ventral chord neurons, and tail neurons of the hermaphrodite, in addition to few unreported pharyngeal neurons (I5, M2, I4, M3, and I1).

• Primary Identifier: Expr10584
• Pattern: The prig-6RIG-6::GFP construct drives expression of all RIG-6 isoforms in fusion with GFP, under their endogenous promoter. rig-6 expression is detected during embryogenesis and is maintained throughout adulthood. rig-6 is expressed in I1 and I3 pharyngeal interneurons, NSM motor neurons and other unidentified head neurons. RIG-6::GFP is also localized in the cell bodies and axons of different subtypes of VNC motorneurons, in the HSN and the CAN neurons. Neuronal expression of rig-6 also includes the ALM and PLM touch receptor neurons. Non-neuronal cells expressing rig-6 include somatic muscles and the hypodermis. We also detected rig-6 expression in the developing and adult EC.

• Primary Identifier: Expr12408
• Pattern: With a construct including 8 kb upstream of the first exon and the entire unc-7 genomic region fused to YFP, UNC-7 expression was found, in addition to the sex muscles reported in Expr12407, in several mating circuit neurons (SPC, PCA, PCB, HOA, HOB, and unidentified ray neurons). Similar to previous studies (Starich et al., 2009; Yeh et al., 2009; Kawano et al., 2011), this reporter also expresses, in head ganglion neurons, several ventral chord neurons, and tail neurons of the hermaphrodite, in addition to few unreported pharyngeal neurons (I5, M2, I4, M3, and I1).

• Primary Identifier: Expr1818
• Remark: Only celluar expression patterns in the mail tale was reported. No detail on expression pattern in other tissues. --wjc.
• Pattern: PCB, PCC, and SPC neurons expressed an unc-17::gfp construct beginning at mid-L4 and continuing throughout adulthood.
