WormMine: ExpressionPattern Expr983

• Pattern: In the gonads of wild-type hermaphrodites, a mid-to-proximal region including pachytene stage cells and oocytes was strongly stained. This strong expression was retained in early embryos and decreased gradually after the 200 cell stage until complete disappearance at the 2-fold stage.
• Primary Identifier: Expr983
• Remark: Topoisomerase IIIa, referred to sequence Y56A3A, identified by curator as Y56A3A.27.

	The C. elegans life stage spanning 0-350min after first cleavage at 20 Centigrade. Proliferate from 1 cell to 560 cells. From start of first cleavage until cleavage is over.		proliferating embryo Ce	WBls:0000004
	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 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 stage after an hermaphrodite animal is fully-developed and reaches maturity.		adult hermaphrodite Ce	WBls:0000057
	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
