Expression of Mox In all panels, anterior is to the left, except panel F (dorsal view, anterior up). Panel A represents a ventral view. Panels B–E represent lateral views, dorsal up Panels A´ and C´ represent SYBR Green staining of the embryos shown in panels A and C. The dashed circle in panel A marks the region of the posterior pit. The arrow and arrowhead in panel A point to expression in the last-formed posterior somites. The arrowhead in panel C (thin section) points to expression in the mesoderm. Developmental stages are indicated (staging system after [9], their supplementary data). Abbreviations: ect, ectoderm; hl, head lobe; j, jaw; L, leg; mes, mesoderm; pp, posterior pit; sp, slime papilla
