Fig 3. Substituting evolved metA alleles into R strains recapitulates cooperative phenotype.

Consortia growth rates of R strains with evolved metA alleles correlates with growth rates of the original evolved strains (p-value < 0.001), including the control metA^WT in the R1 background demonstrating the sufficiency of metA^EVO alleles in the R backgrounds. Error bars indicate the standard error of three biological replicates.
