We extended the study of Escherichia coli mutants defective in conjugation and showed that the mutants with altered lipopolysaccharide, which are defective as recipients with F-like donors, are also defective with the I-like plasmid R64-11. However, the extent of reduction in recipient ability for I-like donors does not correlate either with the effect on recipient ability for F-like donors or with the degree of alteration to the lipopolysaccharide.
我们扩展了对大肠杆菌接合缺陷型突变体的研究,并表明脂多糖发生改变的突变体作为F类供体的受体是有缺陷的,对于I类质粒R64-11也是有缺陷的。然而,I类供体受体能力的降低程度既与对F类供体受体能力的影响无关,也与脂多糖的改变程度无关。
