- 摘要：
- Beneficial mutations fuel adaptation by altering phenotypes that enhance the fit of organisms to their environment. However, the phenotypic effects

- 摘要：
- fits of beneficial mutations once genotypes become better adapted (called diminishing-returns epistasis) in unicellular microbes and single genes. Here, we use Fisher
Data from: Negative epistasis between beneficial mutations in an evolving bacterial population

- 摘要：
- , but they have rarely considered beneficial mutations. We analyzed the effects of epistasis on fitness for the first five mutations
Data from: The basis of antagonistic pleiotropy in hfq mutations that have opposite effects on fitness at slow and fast growth rates
- 负责人：
- DOI：
- doi:10.5061/dryad.5bd50
- 摘要：
- Mutations beneficial in one environment may cause costs in different environments, resulting in antagonistic pleiotropy. Here we describe a nove
Data from: Benefit of transferred mutations is better predicted by the fitness of recipients than by their ecological or genetic relatedness

- 摘要：
- e demonstrated that such interactions are common among beneficial mutations and often follow a pattern consistent with declining evolvability of more fit genotypes
Data from: Evolution of fitness trade-offs in locally adapted populations of Pseudomonas fluorescens
