5 Expression Patterns

| The expression of pha-1::lacZ with additional 2kb of 5'UTR showed identical expression pattern. | Expr1579 | The first expression of the pha-1:lacZ hybrid gene is detectable at the 100 cell stage of embryogenesis (130 minutes of embryonic development; all developmental times refer to time after the first cleavage at 20 degree) in cells that have positions in the embryo corresponding to the pharyngeal and body wall muscle precursors. Expression of the pha-1:lacZ hybrid gene at around 200 minutes of development is detected in about 25 cells that form a cylinder in the anterior part of the embryo. These pha-1:lacZ expressing cells are the pharyngeal precursors. The lineage of most of these cells (26 of 27) is restricted to pharyngeal fate and only the MSaaaaa cell produces pharyngeal cells and non-pharyngeal cells (two neurons of the ring ganglion). As soon as these 27 pharynx precursor cells divide (230-250 minutes), expression of the pha-1:lacZ gene in the pharyngeal precursors ceases and only a few cells in the presumptive pharynx region express the hybrid protein. At 420 minutes of development (2 fold stage) no pha-1:lacZ gene expression in the pharyngeal precursor cells is detectable. pha-1:lacZ expression was also observed in body wall muscle cell precursors. Expression of the pha-1 hybrid protein starts early in all body wall muscle cell precursors and is detectable throughout embryonic development in these cells. | ||
| Sequence: Z28377 Z28375 Z28376. | Expr12 | Embryonic expression consisting of three components. 1. A subset of cells in the AB lineage, initially organized in two clusters, from when the AB lineage is dividing to give 32 cells until the lineage forms 128 cells. Descendants of AB.alpa, AB.alpp, AB.araa, AB.plaa, AB.plpa, AB.praa, AB.prpa. 2. Members of the D cell lineage, starting as Da/Dp divide and ending once 16 cells have been generated in this lineage. 3. Z1 and Z4, from the end of their migration to the germ line progenitors, until shortly after hatching. | ||
| Expr10528 | Inferred Expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo. Quantitative expression data for all cells are located here: ftp://caltech.wormbase.org/pub/wormbase/datasets-published/murray2012/ | |||

| Reporter gene fusion type not specified. T14G12.4 = fkh-2 | Expr1472 | expression was observed in the descendants of the D founder cell. T14G12.4::gfp expression was also detected in many other cells more anteriorly that probably overlap with, but are not identical to, those of the AB founder cell lineage that express the pes-1::gfp fusion gene. |
