The global biogeography of amino acid variants within a single SAR11 population is governed by natural selection.

Delmont, T. O., Kiefl, E., Kilinc, O., Esen, Ö. C., Uysal, I., Rappé, M. S., Giovannoni, S., and Eren, A. M.
- Using single-amino acid variants to investigate genome variation within a single SAR11 population across large geographies.
- Application of a novel Deep Learning algorithm to resolve relationships between metagenomes through complex SAAV data.
- Partitioning of SAAVs suggests natural selection, rather than neutral evolution, is the main driver of the evolution of SAR11.

- An FMT study with metagenome-assembled genomes (see public data).
- Bacteroidales: high-colonization rate. Clostridiales: low colonization rate. Colonization success is negatively correlated with the number of genes related to sporulation.
- MAGs with the same taxonomy showed different colonization properties, highlighting the importance of high-resolution analyses.
- Populations colonized both recipients were also prevalent in the HMP cohort (and the ones that did not, distribute sporadically across the HMP cohort).
