We detected embryonic expression of our rescuing
pal-1::gfp construct, containing the full genomic sequence of
pal-1, in two pairs of epidermal daughter cells, V3 and P7/8, and V4 and V6, from shortly after their birth. In contrast, we were unable to detect any expression of
pal-1 in L1 larvae, supporting the hypothesis that
pal-1 functions in embryos to coordinate L1 ventral epithelial morphogenesis.
