Fig. 2 Increase and decrease in Bmp activity have distinct effects on CE of tissues and embryonic morphology. Graphs showing results of morphometric analysis of WT (blue), sbn (red), and din (green) mutant embryos: (A) embryo length, (B) animal–vegetal length, (C) dorsal mesendodermal length, and (D) thickness of dorsal margin. (E) Lateral view of a WT embryo at the end of the gastrula period (9.5 hpf) with animal pole (AP), vegetal pole (Vg), ventral (V), and dorsal (D) marked. The dorsal and ventral margin thickness and the animal–vegetal dimension are shown. (F) din embryo at 9.5 hpf; embryo length measure is shown. (G) sbn embryo at 9.5 hpf; mesendodermal length measure is indicated (ML). (H) WT, (I) din, and (J) sbn embryos at the beginning of segmentation; mediolateral embryo width is indicated (M-LW; 10.7 hpf). Arrows denote anterior tip of mesendoderm, and arrowheads mark tail region (H–J). A–V, animal–vegetal length; EL, embryo length; ML, mesendoderm length; M-LW, mediolateral width. Scale bar, 100 μm.
