Showing gene expression using the space filling model. Two different views show the same time point, comparing the observed expression with that reported in the literature. These are ventral views with anterior on the left. The coloring scheme on the left characterizes the expression level of the tagged gene: cells expressing the gene are shown clearly with different shades of green and red using the scheme of Figures 7 and 8; non-expressing cells are grayed out. On the right, the sublineages reported in the literature to express the gene are shown with sublineage specific colors and cells not reported to be expressing are grayed out. The sublineage color scheme is: ABal in pink; ABar in blue; E in yellow; MSaa in magenta; MSap in cyan.
