title: Characterization of the phenotype conferred by two different rpsL alleles coding for streptomycin dependence.
abstract: Two streptomycin-dependent strains of E. coli B showing different phenotypes were isolated. They carried different rpsL alleles which conferred two levels of dependence on the drug, and showed a different expression when present in heterozygous conditions with other rpsL alleles, coding for sensitivity or resistance on the drug.
