• Primary Identifier: Expr11217
• Pattern: kpc-1 is expressed in numerous neuronal and epithelial cells during dauer. Processes adjacent to the body wall in dauers resemble those of IL2Q 4 dendrites. To determine whether kpc-1 is expressed in the IL2s, we coinjected the Pkpc-1::GFP reporter with a Pklp-6::tdTomato reporter that is expressed exclusively in the IL2s. During nondauer stages, kpc-1 is not expressed in the IL2 neurons (data not shown). In dauers, Pkpc-1::GFP and Pklp-6::tdTomato are coexpressed, indicating that kpc-1 is upregulated in the IL2s during dauer. Nondauer expression was consistently observed in the ventral nerve cord and pharynx with strong expression in the g2 pharyngeal gland cells and vpi pharyngeal intestinal valve cells.

• Primary Identifier: Expr162
• Remark: Other strains-- UL856, UL853
• Pattern: Strong expression is seen in the excretory cells and canals. Expression in the canals is concentrated in unidentified subcellular structures. Expression is also seen in the terminal bulb of the pharynx, possibly in the g2 gland cell. Expression is most frequently seen in young larvae, but is occasionally seen in embryos and adults.

• Primary Identifier: Expr11043
• Pattern: F48A11.1 was expressed specifically in the period immediately preceding each moult. Expression appeared limited to the pharynx and specifically to the glandular cells g1 and g2 (5 nuclei) in the terminal bulb, the three m4 myo-epithelial cells (6 nuclei) in the metacorpus and the three m3 myo-epithelial cells (6 nuclei) in the pro- corpus. No GFP was detected elsewhere in transgenic nematodes despite careful examination of the reproductive tissues and intestine.
