Evolution of the accessory genome

2026-01-26

Abstract excerpt

The accessory genome, the set of genes variably present across members of a bacterial species, plays a central role in shaping microbial diversity and adaptation. Instead of a random collection of mobile elements, evidence has shown that the accessory genome is structured by selective forces, particularly negative frequency-dependent selection, and underpins the long-term stability of multi-strain bacterial popula...
