Overview
We aim to identification of several genes (e.g., neuropeptides, steroidogenic enzymes, which are supposed to be under the control of GnRH and hormones related with reproduction) from several bivalve species by using PCR and in silico cloning with next-generation sequencing. In addition, we plan to carry out the in vivo experiment with the neuropeptides whether they have a potential for controlling scallop gonad maturation in vivo. While, we also plan to produce the recombinant protein for oocyte maturation arresting factor (OMAF) which inhibitory regulates oocyte release in bivalves by using brand-new bacterial expression system.
