Examples of conserved Fox gene expression domains. (A-E) FoxB expression (blue) in multiple species. The expression of FoxB seems to be correlated to the expression of chordin, a BMP inhibitor. The endodermal gut expression domain seems to be unique to echinoderms and hemichordates. (F-I) FoxD expression (blue) in the hindgut of different species. The conservation of the expression in the hindgut across deuterostomes indicates that it was likely already present in the hindgut of the deuterostome ancestor. (J-O) Ectodermal expression domains of FoxQ2 (blue) in multiple species across phyla. Expression across bilateria suggest a conserved role in apical (apical neural) patterning. Expression at the aboral side in cnidarians suggests a deep evolutionary origin for this expression in patterning terminal neural structures. For literature summary see Table 1 and for additional discussion see Additional file 12. A: anterior, P: posterior, D: dorsal, V: ventral, oa: aboral, o: oral.
