WormMine: ExpressionPattern Expr878

• Pattern: Fluorescence was first seen in some embryonic cells after gastrulation. All expression was confined to nuclei. Several cells in the head and tail, most of which appeared to be neuronal, were fluorescent in larvae and adults. The expression in at least some of the cells varied with time. Authors observed strongest expression and most continuous expression (lasting into the adult) in the FLP cells. The two HSN cells were seen in comma-stage to 1.5-fold stage embryos. Sometimes saw egl-1(+)-dependent expression in cells in the normal HSN position in L1 and L2 larvae, but never in L3 or older animals. In addition to these cells, GFP fluorescence was also found in 11 pairs of ventral cord neurons in the late L1 stage but not later. As many as 10 cells also fluoresced in the heads of L1 larvae. One cell in the tail also fluoresced at hatching, and two additional cells fluoresced at the end of the L1 stage and the beginning of the L2 stage. All of these cells lost their fluorescence as the animals matured. Unexpectedly, the touch cells also expressed the gfp::egl-46 fusion. This expression was transient (mainly in L2 larvae) and much fainter than the expression in the FLP cells (the postembryonically derived AVM and PVM cells fluoresced strongest). Some PVM fluorescence was seen at the L3 stage. gfp::egl-46 was also expressed in the PVD neurons. egl-46 is expressed transiently in the Q lineages.
