Fig. 5. Expression of goosecoid and chordin is ventrally expanded in embryos lacking vox and vent function. Expression of gsc (A-H) and chd (I-P) at 40% epiboly (5 hours) was examined by whole-mount in situ hybridization in wild type (A,I), vox^st9 mutants (B,J), Df^st7/vox^st9 mutants (C,K), Df^st7 mutants (D,L), control MO-injected embryos (E,M), vox MO-injected embryos (F,N), vent MO-injected embryos (G,O), and in embryos co-injected with vox and vent MO (H,P). In B,C,J,K, genotypes were determined by PCR assay after the photographs were taken. Animal pole views, dorsal towards the right.
