Dataset of the bacterial fitness estimation values and mutation identifications from: Rapid decline of adaptation of Pseudomonas fluorescens to soil biotic environment

Interactions between microbes can both constrain and enhance adaptation, but to date, most studies employ simplified communities and environments. We measured fitness of populations of the soil bacterium Pseudomonas fluorescens that have been evolved in both the presence and absence of a natural potting soil microbial community. Populations from both environments showed similar fitness increases with respect to the ancestor in the absence of the community, suggesting no significant cost of evolving with the community. By contrast, fitness in the presence of the community increased for community-evolved populations, but decreased considerably below the ancestral state for populations evolved in the absence of the community. This suggests some abiotic beneficial mutations are costly in the presence of the community, while others are not, with the former only selected against in the presence of the community. Most mutations underpinning fitness changes were clone specific, supporting the v...
