Deuterostomes comprise a monophyletic group of animals that include chordates, xenoturbellids, and the Ambulacraria, which consists of echinoderms and hemichordates. The ancestral chordate probably had 14Hoxgenes aligned linearly along the chromosome, with the posterior six genes showing an independent duplication compared to protostomes. In contrast, ambulacrarians are characterized by a duplication of the posteriorHoxgenes, resulting in three genes known asHox11/13a,Hox11/13b, andHox11/13c. Here, we isolated 12Hoxgenes from the hemichordateBalanoglossus misakiensisand found an extraHoxgene that has not been reported in hemichordates. The extraB. misakiensisgene was suggested to beHox8from paralog-characteristic residues in its hexapepetide motif and homeodomain and a comparison withStrongylocentrotus purpuratus Hoxgenes. Our data suggest that the ancestor of echinoderms and hemichordates may have had a full complement of 12Hoxgenes.
