Table 3 Effect of antisense MO on the ventralizing activity of Bmps. Capped mRNA and glce MOs were injected into the yolk of one- to two-cell embryos as in the experiments of table 1. The resulting phenotypes were scored at 48 hpf. For the rescue experiments, embryos were first injected with bmp2b or bmp4 mRNA and after randomization half received the indicated amount of MO before reaching the 4-cell stage. Phenotype severity was scored as in Table 1.
