WormMine: ExpressionPattern Expr9278

• Pattern: rgef-1 promoter activity is evident in a high proportion of neurons in four independently isolated strains. GFP is not detected in nonneuronal cells. Terminal divisions and differentiation of neurons are completed before rgef-1 promoter activity is switched on during late embryonic development. Panneuronal GFP fluorescence is sustained from the end of embryogenesis (hatching) through adulthood. The rgef-1 promoter is active throughout the nervous system. GFP is evident in head neurons, nerve ring, tail neurons, and nerve cord.
• Primary Identifier: Expr9278

Remark	Definition	Other Name	Public Name	Primary Identifier
	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
