主　　题：Synechococcus phenogenetic diversity co-occurrence network coastal ecosystem Bohai Sea 

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 ***,the abundance distribution and genetic diversity of Synechococcus in this region have rarely been *** 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 *** results demonstrate that phycoerythrin-containing Synechococcus was most abundant in August when temperature was high and oxygen saturation was *** this period,Synechococcus pigment type(PT)2 was abundant in the Bohai Bay and Laizhou Bay under conditions of high nutrient concentration,temperature,and *** 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,pH,and oxygen ***,co-occurrence correlations using network analysis revealed that Synechococcus PTs were related to 15.37%-43.48%of the prokaryotic *** PT3c/PT3d and PT2 were the most important PTs in the *** hierarchical clustering revealed that taxa co-occurred with Synechococcus PTs diff ered among *** could be attributed to the substance exchange and the environmental impact,which calls for more studies in the future.
