WormMine: ExpressionPattern Expr10802

• Pattern: Prominent gtr-1 expression was observed in the head and tail neurons and along the ventral cord. gtr-1 is expressed in chemosensory neurons. gtr-1 is expressed in neither the AFD thermosensory neurons, nor in AIY interneurons. Temporal analysis of gtr-1 expression revealed that signal was first observed in a single location at the 1.5-fold embryonic stage. At the 3-fold stage, clear signals were detected in two areas corresponding to the head and tail regions of the developing embryo, whereas at late morphogenesis, signals were seen in the head and tail and along the developing embryo's body. In L1 larvae signals were observed in the head, tail, and ventral cord and in L2 and L3 larvae in ADL and AIZ neurons.
