Abstract

Many sequences from picoeukaryotes were found in DNA sequence data assembled from Sargasso seawater.

Highlights

  • With genome sequencing becoming more and more affordable, environmental shotgun sequencing of the microorganisms present in an environment generates a challenging amount of sequence data for the scientific community

  • These sequence data enable the diversity of the microbial world and the metabolic pathways within environments to be investigated [3,4,5], a previously unthinkable achievement when using traditional approaches, since it has been estimated that 99% of marine microorganisms can not be cultured in the laboratory [6]

  • To retrieve the eukaryotic scaffolds from the Sargasso Sea Database (SSD), we used a reference dataset for each gene chosen as an anchor

Summary

Introduction

With genome sequencing becoming more and more affordable, environmental shotgun sequencing of the microorganisms present in an environment generates a challenging amount of sequence data for the scientific community These sequence data enable the diversity of the microbial world and the metabolic pathways within an environment to be investigated, a previously unthinkable achievement when using traditional approaches. Genome sequencing is becoming more and more affordable and shotgun sequencing using DNA from environmental microbial communities provides the scientific community with a challenging amount of sequence data (see [1,2], for a review) These sequence data enable the diversity of the microbial world and the metabolic pathways within environments to be investigated [3,4,5], a previously unthinkable achievement when using traditional approaches, since it has been estimated that 99% of marine microorganisms can not be cultured in the laboratory [6]. The two genera Prochlorococcus and Synechococcus were clearly dominant, as described for many other areas [9,13]
