WormMine: ExpressionPattern Expr11871

• Pattern: AJM-1::GFP is first detected in wildtype embryos beginning at the lima-bean stage (350 min post-fertilization) in the central region of the primordial pharynx. Expression of AJM-1::GFP is also observed in the region corresponding to the arcade cells beginning at around the comma stage (400 min), coincident with the onset of reorientation. Expression of AJM-1::GFP increases throughout the 1.5- and 2.0-fold stages of embryogenesis in both the pharynx and arcade regions of wild-type embryos (430-450 min).

	The C. elegans life stage spanning 420-460min 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 fold back 50%. A stage between comma embryo and 2-fold embryo.		1.5-fold embryo Ce	WBls:0000018
	The C. elegans life stage spanning 390-420min 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 looks like a comma. A stage between bean embryo and 1.5-fold embryo.		comma embryo Ce	WBls:0000017
	The C. elegans life stage spanning 460-520min 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 double fold. A stage between 1.5-fold embryo and 3-fold embryo.		2-fold embryo Ce	WBls:0000019
	The C. elegans life stage spanning 350-390min 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. Emrbyo elongation started but have not formed comma shape yet. The shape of embryo looks like a lima bean. A stage right before comma embryo. Also called lima embryo or lima bean stage.		bean embryo Ce	WBls:0000016
