• Primary Identifier: Expr2720
• Remark: No GO_term assigned.
• Pattern: Strong reporter gene expression was first observed in the hypodermal seam cells during embryogenesis and subsequently in the seam cells of all larval stages. The main hypodermal syncytium, hyp7, of larvae and young adult nematodes also displayed reporter gene activity. Strong GFP expression was observed in the toroid cells that form the developing vulva in the L4 larval stage and expression persisted into early adulthood, but was not present in the vulva of mature hermaphrodites. In addition to the hypodermal expression described above for hermaphrodites, intense reporter gene activity was also observed in the developing ray papillae of the L4 male tail. Young adult males exhibited weak expression, restricted to the hypodermis just anterior to the tail. No transgene expression was detected in the dauer larvae, but expression re-appeared approximately 12 h after dauers had been transferred to a fresh lawn of E. coli.
• Subcellular Localization: The expression in individual seam cells was often highly punctate.
