Abstract
Plasmids transferred between bacteria prevented from expressing genes by the presence of bacteriostatic antibiotics. Whereas it has long been known that de novo gene expression is not required in donor cells for conjugation, the observations reported here extend the autonomy of plasmid transfer to the early events of establishment in recipients. In addition, this phenomenon was extended to bacteriophage lambda.
摘要
在抑菌性抗生素存在的情况下，细菌之间转移的质粒无法表达基因。虽然长期以来人们都知道供体细胞在进行接合时不需要从头进行基因表达，但此处报道的观察结果将质粒转移的自主性扩展到了受体细胞中质粒建立的早期事件。此外，这种现象还扩展到了λ噬菌体。
