Low genomic diversity in tropical oceanic N2-fixing cyanobacteria.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
High levels of genomic and allelic microvariation have been found in major marine planktonic microbial species, including the ubiquitous open ocean cyanobacterium, Prochlorococcus marinus. Crocosphaera watsonii is a unicellular cyanobacterium that has recently been shown to be important in oceanic N2 fixation and has been reported from the Atlantic and Pacific oceans in both hemispheres, and the Arabian Sea. In direct contrast to the current observations of genomic variability in marine non-N2-fixing planktonic cyanobacteria, which can range up to >15% nucleotide sequence divergence, we discovered that the marine planktonic nitrogen-fixing cyanobacterial genus Crocosphaera has remarkably low genomic diversity, with <1% nucleotide sequence divergence in several genes among widely distributed populations and strains. The cultivated C. watsonii WH8501 genome sequence was virtually identical to DNA sequences of large metagenomic fragments cloned from the subtropical North Pacific Ocean with <1% sequence divergence even in intergenic regions. Thus, there appears to be multiple strategies for evolution, adaptation, and diversification in oceanic microbial populations. The C. watsonii genome contains multiple copies of several families of transposases that may be involved in maintaining genetic diversity through genome rearrangements. Although genomic diversity seems to be the rule in many, if not most, marine microbial lineages, different forces may control the evolution and diversification in low abundance microorganisms, such as the nitrogen-fixing cyanobacteria.
