We describe a new class of mutants of Escherichia coli K-12 defective in conjugation (Con(-) mutants). They lack a major protein of the outer membrane and are defective as recipients with Hfr and F' donors and as recipients for several F-like R factors and Col factors. In the case of crosses with an Hfr donor, we have shown that the Con(-) recipient is defective in pair formation. The mutants are resistant to certain phages due to loss of receptor activity.
我们描述了一类新的大肠杆菌K-12接合缺陷型突变体(Con(-)突变体)。它们缺乏外膜的一种主要蛋白质,作为Hfr和F'供体的受体以及几种F样R因子和Col因子的受体存在缺陷。在与Hfr供体杂交的情况下,我们已经表明Con(-)受体在配对形成方面存在缺陷。由于受体活性丧失,这些突变体对某些噬菌体具有抗性。
