Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  Staining observed using lacZ reporter (Expr7998) was confirmed. In addition, staining for the PHY-4.1 polypeptide was found in the excretory duct of the excretory system. Primary Identifier  Expr7999
Remark  Picture: Fig. 4B. Subcellular Localization  Staining was seen in the pharynx lumen and at the boundary between the pharynx and the gut.

Definition Name Synonym Primary Identifier
A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine. pharyngeal-intestinal valve cardia WBbt:0005767

  The third stage larva. At 25 Centigrade, it ranges 32.5-40 hours after fertilization, 18.5-26 hours after hatch. L3 larva Ce WBls:0000035
  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
