Low energy cost for cultured pearl formation in grafted chimeric Pinctada margaritifera

Abstract The pearl oyster is one of the rare animal models that support two distinct genomes, through the surgical graft process operated for culture pearl production. This grafted organism is assimilated to a chimera whose physiological functioning remains poorly known. The question of the energy e...
