| contents | Hybridization breaks species barriers in long-term coevolution of a cyanobacterial population. Birzu, Gabriel Subrahmaniam Muralidharan, Harihara Goudeau, Danielle Malmstrom, Rex R Fisher, Daniel S Bhaya, Devaki Cyanobacteria Hybridization, Genetic Genome, Bacterial Genetic Variation Evolution, Molecular Hot Springs Recombination, Genetic Biological Evolution Biological Coevolution Selection, Genetic Bacterial species often undergo rampant recombination yet maintain cohesive genomic identity. Ecological differences can generate recombination barriers between species and sustain genomic clusters in the short term. But can these forces prevent genomic mixing during long-term coevolution? Cyanobacteria in Yellowstone hot springs comprise several diverse species that have coevolved for hundreds of thousands of years, providing a rare natural experiment. By analyzing more than 300 single-cell genomes, we show that despite each species forming a distinct genomic cluster, much of the diversity within species is the result of hybridization driven by selection, which has mixed their ancestral genotypes. This widespread mixing is contrary to the prevailing view that ecological barriers can maintain cohesive bacterial species and highlights the importance of hybridization as a source of genomic diversity. |
