show Abstracthide AbstractCoastal surface water was collected from the end of the pier located at the Scripps Institution of Oceanography, La Jolla, CA on October 10, 2006. A concentrated marine picoplankton sample was by filtration between a size range of 0.45-2.0 .M, and Synechococcus cells were concentrated by flow cytometry. Whole genomic DNA was prepared from the Synechococcus-enriched metagenomic sample, amplified by Genomphi and sequenced by 454 sequencing. 454 sequence data is available from the Short Read Archive (SRA): <a href="ftp://ftp.ncbi.nih.gov/pub/TraceDB/ShortRead/SRA001124 ">SRA001124</a>.
