Fig. 1 Mhwatsu01sm mutant phenotype. (A) Morphogenesis of live wild-type (WT) and mutant embryos. The black arrowhead and arrows indicate the dorsal organizer and the thickening body axis, respectively; the red arrows in mutants indicate the thicker blastodermal marginal zone. See also movie S1. (B and C) Germ layer marker expression detected by WISH during gastrulation. Orientation: ntla and sox17, dorsal views with animal pole to the top at 75% epiboly stage; others, lateral views (gsc, chd, bmp4, eve1, and gata2a) or animal-pole view (otx2) with dorsal to the right. (D) Marker expression at 24 hpf. Lateral views with anterior to the left. Scale bars, 100 μm.
