| Abstract |
The genus Prochlorococcus is globally abundant and dominates the total phytoplankton biomass and production in the oligotrophic ocean. The single species, Prochlorococcus marinus, comprises six named ecotypes. Our aim was to analyze the taxonomic structure of the genus Prochlorococcus. We analyzed the complete genomes of 13 cultured P. marinus type and reference strains by means of several genomic taxonomy tools (i.e., multilocus sequence analysis, amino acid identity, Karlin genomic signature, and genome to genome distance). In addition, we estimated the diversity of Prochlorococcus species in over 100 marine metagenomes from all the major oceanic provinces. According to our careful taxonomic analysis, the 13 strains corresponded, in fact, to ten different Prochlorococcus species. This analysis establishes a new taxonomic framework for the genus Prochlorococcus. Further, the analysis of the metagenomic data suggests that, in total, there may only be 35 Prochlorococcus species in the world's oceans. We propose that the dearth of species observed in this study is driven by high selective pressures that limit diversification in the global ocean. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 December 2013.
All research outputs
#13,661,887
of 23,577,654 outputs
Outputs from Microbial Ecology
#1,193
of 2,090 outputs
Outputs of similar age
#104,828
of 200,602 outputs
Outputs of similar age from Microbial Ecology
#11
of 15 outputs
Altmetric has tracked 23,577,654 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,090 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 41st percentile – i.e., 41% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 200,602 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
