Analyzing the origin of adaptive mutations in saccharomyces cerevisiae

In this study, we use dna sequences from four closely related clades of saccharomyces paradoxus and saccharomyces cerevisiae to identify and polarize new mutations and estimate their fitness effects by progressively restricting the analyses to narrower categories of sites, we further seek to characterize sites with predictable mutational . In the yeast saccharomyces cerevisiae , beneficial mutations selected during sulfate-limited growth are typically amplifications of the [sul1][1] gene, which encodes the high-affinity sulfate transporter, resulting in fitness increases of 35% .
