WormMine: ExpressionPattern Expr16391

• Pattern: We examined a GRH-1:: GFP::3xFLAG fusion protein expressed from the endogenous grh-1 locus. We observed the first detectable signal in elongating embryos, that is, at the time when oscillatory gene expression initiates (Meeuse et al, 2020). In larvae, GFP signal accumulated in various cell types, including seam cells, vulva precursor cells, non-seam hypodermal cells, pharyngeal cells, and head neurons. Finally, in adults, which lack oscillatory gene expression (Meeuse et al, 2020), GFP levels were diminished or altogether absent in various tissues.

	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 350-620min 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 stage that embryo starts elongation until elongation is over.		elongating embryo Ce	WBls:0000015
