Comments P.813 right column top paragraph: "Current estimates for Ua [beneficial mutation rate] fall around 10^–9 to 10^–8 for RNA viruses and Escherichia coli (primary sources). A similar beneficial mutation rate was estimated for Pseudomonas fluorescens under adaptation to stressful conditions (ref 9). A caveat for all of these estimates is that they were obtained from populations with very large effective population size (Ne) and followed adaptation to a new environment under conditions in which clonal interference had a strong effect. This led to downward biased estimates of Ua. Here, [investigators] provide estimates for the genomic mutation rate for beneficial mutations in E. coli that are less biased by clonal interference."
