WormMine: ExpressionPattern Expr14875

• Pattern: To our surprise, we also found that the egl-1 reporter was expressed in adult animals in a very small subset of neurons, and in one pair especially strongly in all individuals. This expression persisted throughout the entire life of the worm. We used cell-specific reporters and morphological characterization to identify the neurons most brightly expressing the reporter as the bilaterally symmetric neuron pair URX (YU et al. 1997). By examining eggs, we found that egl-1 reporter expression was detectable in URX by at least the 3-fold stage, albeit at extremely faint levels compared to later expression. In addition to URX, we also found that AQR, PQR and one of the AWCon/off neuron pair expressed the reporter less often. Of these neurons, the expression in the URX neuron pair was the most consistent and robust.

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo.		fully-elongated embryo Ce	WBls:0000021
	A developmental life stage of the nematode Caenorhabditis elegans that occurs from egg hatching until adulthood.		larva Ce	WBls:0000023
	The C. elegans life stage spanning 520-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage.		3-fold embryo Ce	WBls:0000020
