The Pmar1-unresponsive genes wnt8, blimp1, and brachyury (Bra) (circled with hatched black lines) are dispensable for ectopic Pmar1-mediated endomesoderm induction, which probably occurs without inducing ectopic nuclearization of β-catenin in animal blastomeres.

(B) blimp1 expression at 14-16 h p.f. (C) wnt8 expression at 14-16 h p.f. (D) brachyury expression at 20 h p.f. Embryos shown are representative of 100\% of at least 50 embryos in each of three separate experiments in which gfp mRNA was detected in nonvegetal regions.

(B) Embryos were treated with either (a-c) DMSO or (g-i) SB (5 μM) and analyzed by WMISH to detect (a and g) brachyury at 18 h, (b and h) blimp1 at 14 h, and (c and i) wnt8 at 14 h.
