Negative frequency-dependent selection contributes to modular structure of effector repertoires in Pseudomonas syringae

The paper uses a computational model to show that negative frequency-dependent selection contributes to the modular structure of effector repertoires in Pseudomonas syringae.

The evolutionary cost of homophily: social stratification facilitates stable variant coexistence and increased rates of evolution in host-associated pathogens

This study shows that host population social stratification increases pathogen strain diversity by creating balancing selection pressures that support stable viral coexistence.
