Expression Pattern :

Pattern  GFP expression was first observed in several posterior cells of comma stage embryos, then in the excretory cell and some head neurons in threefold stage embryos. In L1 to adult worms, continued expression of GFP was observed in several head neurons, the excretory cell and the excretory gland cells, as well as the sphincter muscles. One of the head neurons was identified as the AVG neuron based on the cell position and morphology. In addition, in L4 worms, GFP was seen in a set of hypodermal cells surrounding the vulva, which persisted in the hypodermal cells flanking the vulval opening in adult worms. No GFP expression was detected in the sensory neurons. Faint GFP expression was infrequently detected in one to four neurons in the ventral cord. No expression was observed in the sex myoblasts, nor was GFP detected in the body wall muscles at any stages. Primary Identifier  Expr2572
Reporter Gene  [unc-71::gfp] transcriptional fusion. To generate the unc-71 transcriptional GFP construct pCZ411, the 1.7 kb upstream regulatory region of unc-71 was amplified by PCR, and inserted into pPD95.79.
