Presence of Proboscipedia and Caudal Gene Homologues in a Bivalve Mollusc

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...
