| 英文摘要 | Synechococcus is one of the most abundant picocyanobacteria in marine ecosystem, and the absence of Prochlorococcus would make it indispensable as a primary producer in the Bohai Sea, North China. However, the abundance distribution and genetic diversity of Synechococcus in this region have rarely been reported. In this study, the distribution pattern of Synechococcus abundance was investigated during four cruises in April, June, August, and November from 2018 to 2019, moreover, its phenogenetic diversity was studied based on high-throughput sequencing of the cpe BA operon. The results demonstrate that phycoerythrin-containing Synechococcus was most abundant in August when temperature was high and oxygen saturation was low. During this period, Synechococcus pigment type(PT) 2 was abundant in the Bohai Bay and Laizhou Bay under conditions of high nutrient concentration, temperature, and turbidity. In comparison, PT3, especially those clusters characterized with high or variable ratio of phycourobilin and phycoerythrobilin, was predominant in the Bohai Strait and Liaodong Bay under conditions of high salinity, p H, and oxygen saturation. Furthermore, co-occurrence correlations using network analysis revealed that Synechococcus PTs were related to 15.37%-43.48% of the prokaryotic genera. Synechococcus PT3c/PT3d and PT2 were the most important PTs in the network. The hierarchical clustering revealed that taxa cooccurred with Synechococcus PTs differed among samples. It could be attributed to the substance exchange and the environmental impact, which calls for more studies in the future. |
