Abstract

A heat-inducible lysis-defective lambda prophage has been integrated directly into the E. coli chromosome at a site (bfe) very closely linked to the ribonucleic acid polymerase mutation rif(d), a dominant rifampin resistance allele. This unusual lysogen has facilitated the isolation of specialized transducing phages conferring rifampin resistance to sensitive cells, and carrying at least the beta subunit gene of RNA polymerase in intact form.

摘要

一种热诱导裂解缺陷型λ原噬菌体已直接整合到大肠杆菌染色体的一个位点(bfe),该位点与核糖核酸聚合酶突变rif(d)紧密连锁,rif(d)是一个显性利福平抗性等位基因。这种不同寻常的溶原菌有助于分离出能使敏感细胞获得利福平抗性的特异性转导噬菌体,这些噬菌体至少完整携带RNA聚合酶的β亚基基因。
