The link between independent acquisition of intracellular gamma-endosymbionts and concerted evolution in Tremblaya princeps.

abstract：:In the environment, bacteria live in complex multispecies communities. These communities span in scale from small, multicellular aggregates to billions or trillions of cells within the gastrointestinal tract of animals. The dynamics of bacterial communities are determined by pairwise interactions that occur between di...
