Tóm tắt

The cnidarian microbiome consists of a wide variety of beneficial microbes that play vital roles in maintaining and fortifying host health. Photosynthesis from symbiotic dinoflagellates (in the family Symbiodiniaceae) is crucial for their symbiosis establishment with the cnidarian host. Although more is known regarding interactions between the host and its associated bacteria and dinoflagellates, there has been little investigation into the relationship between the two microbes themselves and whether photosynthesis plays a role. Through two different methods of photosynthetic inhibition of dinoflagellates (incubation in the dark or pre-treatment with a photosystem II inhibitor), we investigated how pathogenic versus beneficial bacteria physically interact with three Symbiodiniaceae strains (symbiotic and free-living). The beneficial bacterium
