WormMine: ExpressionPattern Expr13244

• Pattern: Pmemo-1::GFP is expressed in some neurons in the head of an L4 wild-type worm, e.g., amphid neurons, including ASJ, and also non-neuronal tissues, such as the pharynx (the procorpus, the anterior bulb, the isthmus and the terminal bulb). In young, adult wild-type worms, Pmemo-1::GFP is expressed in tail neurons, the posterior end of the intestine and the rectal area. Strong Pmemo-1::GFP expression was detected in tail neurons and weaker expression in the posterior end of the intestine and the rectal area. Pmemo-1::GFP is expressed in the adult vulva. Pmemo-1::GFP is expressed in the spermatheca of wild-type adults. Pmemo-1::GFP is expressed during vulva development at the L4 stage. In an early L4, Pmemo-1::GFP::GFP is expressed weakly around the vulva and expressed strongly in the anchor cell and the vulval precursor cells. There is also strong expression in the ventral cord neurons. Pmemo-1::GFP is expressed in the distal tip cells.

neuron with cell body associated with the ventral nerve cord.	ventral cord neuron	ventral cord motoneuron	WBbt:0005300
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
