WormMine: ExpressionPattern Expr9756

• Pattern: Strains generated for this reporter gene fusion appeared quite mosaic with most individuals showing few GFP expression pattern components. Several cells expressed GFP in and around the posterior pharyngeal bulb. GFP expression was also observed in the intestine. Rarely, GFP expression in the pharyngeal-intestinal valve and hypodermis was observed. Approximately 4 cells [possibly rectal muscle] sometimes gave GFP expression in the tail.

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
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772
