Fig. 5. tlp-1 expression. A functional tlp-1 reporter construct is strongly expressed in the nuclei of the posterior intestine cells, weakly expressed in the nuclei of T and its descendent cells, as well as the tail hypodermal cells. (A-G) Fluorescence (upper) and DIC optics (lower). Scale bars: 10 µm. (A) GFP expression in most nuclei of an embryo at approximately 100 minutes when four E cell descendants were present, (B) most nuclei of a gastrulating embryo, (C) the nuclei of posterior cells in an embryo at approximately 270 minutes and (D) the nuclei of posterior cells in a 1.5-fold embryo. (E) GFP expression in the T cell. We also observed that few animals had GFP expression in the hyp9, hyp10 and hyp11 cells. (F) GFP expression in the T.p cell and (G) the T.app cell.
