WS295

Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  Strong expression is seen in the large posterior nuclei of the intestine, in adults and late larval stages. There is some variability in the number of nuclei staining. Usually the extreme posterior nuclei stain first. Occasionally in 3-fold embryos a few nuclei show b-galactosidase expression. All injected lines show this expression. This fusion contains all the intergenic region, though this region is only separated from F38B6.5 (the next upstream gene) by ~0.5kb, and so could be a downstream gene; the promoter driving expression of F38B6.4 would then not be included in the construct. Primary Identifier  Expr104
Remark  Other strains-- UL335, UL336 late embryo(author) = 3-fold embryo(curator).

any of 20 large epithelial cells which form a tube and are mostly situated as bilaterally symmetric pairs around the tubular lumen. Each of these cell pairs forms an intestinal ring ( II-IX int rings). The most anterior intestinal ring (int ring I), however, is made of four cells. Intestinal cells contain large nuclei with large nucleoli and numerous autofluorescent granules in their cytoplasm. intestinal cell   WBbt:0005792

  The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch. L4 larva Ce WBls:0000038
  The C. elegans life stage spanning 520-620min 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 tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage. 3-fold embryo Ce WBls:0000020
