A diet rich in diatom improves the antibacterial capacity of Pacific oyster Crassostrea gigas by enhancing norepinephrine-regulated immunomodulation
Microalgae such as dinoflagellate and diatom are the major food source of bivalve species, and sufficient food intake contributes to the immunity and the growth of bivalves. In the present study, a monoamine oxidase gene (named as CgMAO), which is the rate-limiting enzyme of norepinephrine (NE) bios...
