CSIC ORCID | Fecha de publicación: | mar-2016 | Editor: | Nature Publishing Group | Citación: | Nature Communications 7: 11071 (2016) | Resumen: | The unicellular cyanobacterium UCYN-A, one of the major contributors to nitrogen fixation in the open ocean, lives in symbiosis with single-celled phytoplankton. UCYN-A includes several closely related lineages whose partner fidelity, genome-wide expression and time of evolutionary divergence remain to be resolved. Here we detect and distinguish UCYN-A1 and UCYN-A2 lineages in symbiosis with two distinct prymnesiophyte partners in the South Atlantic Ocean. Both symbiotic systems are lineage specific and differ in the number of UCYN-A cells involved. Our analyses infer a streamlined genome expression towards nitrogen fixation in both UCYN-A lineages. Comparative genomics reveal a strong purifying selection in UCYN-A1 and UCYN-A2 with a diversification process ~91 Myr ago, in the late Cretaceous, after the low-nutrient regime period occurred during the Jurassic. These findings suggest that UCYN-A diversified in a co-evolutionary process, wherein their prymnesiophyte partners acted as a barrier driving an allopatric speciation of extant UCYN-A lineages | Descripción: | Cornejo-Castillo, Francisco M. ... et al.-- 9 pages, 3 figures, 1 table, supplementary data, supplementary information http://dx.doi.org/10.1038/ncomms11071.-- This article is contribution number 37 of Tara Oceans | Versión del editor: | https://doi.org/10.1038/ncomms11071 | URI: | http://hdl.handle.net/10261/131710 | DOI: | 10.1038/ncomms11071 | Identificadores: | e-issn: 2041-1723 |
