英文摘要	Synechococcus is a widely distributed photosynthetic pico-phytoplankton, which contributes mainly to carbon fixation and maintains the stability of the marine ecosystem. To investigate its distribution patterns in the Yellow Sea, seawater samples were collected during September 2018. Results of flow cytometry analysis showed that the Synechococcus abundance ranged from 6.36 x 10(2) to 4.51 x 10(4) cells mL(-1), which correlated with salinity (P <0.01) and temperature (P <0.05). At deeper off-shore sites, Synechococcus showed high abundance at the subsurface thermo-halocline, which was in accordance with chlorophyll a (Chl a) content along the vertical column. Based on the high-throughput sequencing data of rpoC1 (partial gene encoding RNA polymerase), two Synechococcus subclusters, S5.1 and S5.2, were found to coexist in the studied area. Several clades of S5.1, including Clades I, II, and III, were the dominant components, accounting for 6.63%, 26.11%, and 45.5% of the total genus, respectively. Redundancy analysis (RDA) showed that nitrite was the main environmental factor that explained the genus composition among samples. Furthermore, co-occurrence network revealed that the main phyla that coexisted with Synechococcus were Proteobacteria, Bacteroidetes, Actinobacteria, Planctomycetes, and Verrucomicrobia, which were involved in the carbon (C), nitrogen (N), sulfur (S), and manganese (Mn) cycles. Overall, Synechococcus exhibited biogeographic distribution correlated with temperature-salinity and nitrite in the Yellow Sea, and their geochemical function showed diverse but should be further verified in the future.
