Research Abstract

In this study, ocean basin-scale dynamics of microbial communities has been revealed with the use of 454 pyrosequencing technology and nucleoside tracer techniques. Although there are some caveats against insufficient read length and diversity inflation due to sequencing errors, deep sequencing of 16S rRNA genes shows the presence of diverse rare taxa and their active growth in seawater environments.
