Fig. 8. Projection of three-dimensional images of reporter expression patterns for
PAL-1 target genes likely to be involved in patterning. Dorsal and lateral
views of chromosomally integrated transcriptional reporters 210 minutes after
the four-cell stage (22°C; 
200 cells, 16 C-lineage cells) are shown
for 13 validated targets. Images are orthogonal perspectives following
three-dimensional volume rendering of many optical sections. A broken gray
line marks the approximate outline of each egg case. (A) Ordination: 8 C
ectodermal nuclei in blue, 8 C muscle nuclei in red and 4 D muscle nuclei in
yellow; (B) pal-1; (C) vab-7; (D) cwn-1; (E)
C55C2.1; (F) unc-120; (G) hnd-1; (H) hlh-1; (I)
elt-3; (J) mab-21; (K) nhr-25; (L) nob-1;
(M) tbx-8; (N) tbx-9. Movies for each reporter are available
in the supplementary material.
