title: Small is Plentiful.
abstract: Rhizobia are legume symbionts that arise through horizontal transfer of symbiotic genes among soil bacteria. A recent study shows that these transfers occur frequently at a micro-scale, leading to unexpected rhizobial diversity and emergence of symbiovars within species. This confirms the disconnection between function and taxonomy in bacterial communities.
