英文摘要The marine Synechococcus isa major primary producer in the global oceans. It is phylogenetically highly diverse, and its major phylogenetic lineages display clear spatial segregation among different marine environments. Here, we showed that the composition of the associated bacterial communities was related to the geographic origin of the different Synechococcus strains, and it was stable during long-term lab incubation. Of all the Synechococcus cultures investigated, the Rhodobacteraceae had a relatively high abundance and was the core bacterial family of the associated bacterial communities. In contrast, the Flavobacteriaceae were only abundant in the cultures collected from the South China Sea (which is warm and oligotrophic), whereas those of the Alteromonadaceae were abundant in the cultures from the coastal waters off Hong Kong and Xiamen. We also found that the Rhodobacteraceae had more ABC transporters and utilized a wider spectrum of carbon sources than did the Flavobacteriaceae and Alteromonadaceae. Moreover, the Alteromonadaceae had more transporters for importing phosphate and amino acids, but fewer transporters for importing oligosaccharides, polyol, and lipid, than the Flavobacteriaceae. Furthermore, metagenomic analysis demonstrated that bacteria involved in nitrateammonification prevailed in all the cultures. These results imply that networks formed by phytoplankton and heterotrophic bacteria might vary across habitats, and that different dominant bacterial groups play different roles in the phycosphere. This study provides new insight into the unique interactive and interdependent bond between phytoplankton and their associated microbiome, which may enhance our understanding of carbon and nutrient cycling in marine environments.
