Involvement of B-aat1 and Cbs in regulating mantle pigmentation in the Pacific oyster (Crassostrea gigas).

These results implied that pheomelanin synthesis was possible induced by CgB-aat1-CgTyr-CgCbs axis, and it played an essential role on mantle pigmentation in the oysters. These findings provide the useful genetic knowledge and enrich the physiological information for the shell color formation in bivalve aquaculture.
