Picocyanobacterial Diversity and Distribution During Summer in the Northern East China Sea
In order to understand the spatial distribution of picocyanobacterial diversity during the summer in the northern East China Sea (ECS), their genetic diversity were investigated using barcoded amplicon pyrosequencing of 16S-23S internal transcribed spacer sequences. Eleven Synechococcus clades and five Prochlorococcus ecotypes were found to have a proportion higher than 1% among picocyanobacterial sequences, indicating high picocyanobacterial diversity in the ECS. The picocyanobacterial compositions were markedly different among stations, as well as among depths.
