Shin, Anthraquinones and Sterols from the Korean Marine Echiura
Urechis unicintus, J.
Polychaeta Myzostomida, Pogonophora, Echiura
These data make it possible to confirm that the homeodomain of the Gbx family was highly conserved among five distinct families of bivalve molluscs (Solenidae, Pectinidae, Veneridae, Ostreidae, and Mytilidae), and the presence of Gbx genes in Mollusca, Annelida, Echiura
, Echinodermata, and Arthropoda supports the idea that Gbx genes were already present in the last common ancestor of the deuterostomes and protostomes.
