Selection of laboratory wild-type phenotype from natural isolates of Escherichia coli in chemostats.

abstract：:Negative genetic regulators of phenotypic heterogeneity, or phenotypic capacitors/stabilizers, elevate population-average fitness by limiting deviation from the optimal phenotype and increase the efficacy of natural selection by enhancing the phenotypic differences among genotypes. Stabilizers can presumably be switch...
