"As expected, in the absence of heat shock, approximately 25% of JG48 embryos were arrested in development and all showed fewer than 17
dpy-7::GFP-expressing cells (Fig. 5A). In contrast, heat shock induction of
elt-3 expression in JG48 embryos caused widespread
dpy-7::GFP expression in almost all of the embryos examined, 25% of which were predicted to be
elt-1(
zu180) homozygotes (Fig. 5B). Indeed, comparison of heat-shocked JG48 embryos with heat-shocked JG10 embryos (genotype cals10 ijls12 but wild type for the
elt-1 gene) revealed no differences either in the proportion of embryos with widespread
dpy-7::GFP expression (Fig. 5B and C) or in the number of
dpy-7::GFP-expressing cells in individual arrested embryos (data not shown)."
