27 Expression Patterns

• Primary Identifier: Expr13117
• Pattern: Refers to NEXTDB In-situ hybridization pattern in the adult gonad. central + proximal

• Primary Identifier: Expr12797
• Pattern: tat-2 reporter is first clearly detectable in 2-fold stage embryos in two sets of pharyngeal cells, the developing pharyngeal-intestinal valve and a set of cells in the posterior. By the first larval (L1) stage, GFP fluorescence also appears in the intestine. L4 and adult animals exhibit reporter signals in unidentified cells of the pharyngeal procorpus, the gland cells located in the posterior bulb of the pharynx, the pharyngeal-intestinal valve, rectal gland cells, the intestine and all cells of the excretory system. tat-2 reporter signals are also seen in L4 larvae in the primary vulval lineage vulE and vulF cells and in the proximal gonad. The vulval fluorescence vanishes and a moderately strong uterine signal appears after the uterine-vulval connection is complete in adults. The gonadal signal, emanating from spermatids, migrates to the spermatheca around the time of the first ovulation.

• Primary Identifier: Expr13120
• Pattern: Refers to NEXTDB In-situ hybridization pattern in the adult gonad.

• Primary Identifier: Expr1200109
• Pattern: Data from the TransgeneOme project

• Primary Identifier: Expr12799
• Pattern: Notable tat-4 reporter expression begins in 2-3 fold embryos in the developing pharyngeal-intestinal valve and unidentified cells at the posterior. In the fully formed alimentary system, GFP fluorescence emanates strongly from the pharyngeal-intestinal valve, rectal gland cells and the intestine. tat-4 reporter is also expressed in the uterus, during spermatogenesis in the proximal gonad and in the spermatheca of previously ovulated adults.
