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.
分离出了两株表现出不同表型的大肠杆菌B链霉素依赖菌株。它们携带不同的rpsL等位基因，这些等位基因赋予了对该药物两种不同程度的依赖性，并且当与其他rpsL等位基因处于杂合状态时表现出不同的表达，其他rpsL等位基因编码对该药物的敏感性或抗性。
