Microarray: a global analysis of biomineralization-related gene expression profiles during larval development in the pearl oyster, Pinctada fucata

Background The molluscan Pinctada fucata is an important pearl-culturing organism to study biomineralization mechanisms. Several biomineralization-related genes play important roles regulating shell formation, but most previous work has focused only on their functions in adult oysters. Few studies have investigated biomineralization during larval development, when the shell is initially constructed and formed until the juvenile stage in dissoconch shells. Here, we report, for the first time, a global gene analysis during larval development of P. fucata based on a microarray and reveal the relationships between biomineralization-related genes and the shell formation process.
