Homeobox genes encode a family of transcription factors that have essential roles in regulating the development of eukaryotes. Although they have been extensively studied in different phyla, relatively little is known about homeobox-containing genes and their function in molluscs. In this study, we used a polymerase chain reaction to investigate homeobox genes in the bivalve mollusc Pecten maximus. Four different homeobox sequences were identified; two were homologues of the non-Hox cluster gene caudal and the two remaining sequences had a significant homology to the ANT-C gene proboscipedia. These sequences represent the first cad and pb homologues isolated from a member of the class Bivalvia, phylum Mollusca.
