Abstract
The temperature-sensitive conjugational transfer-deficient mutant Escherichia coli JCFL39, carrying a traD(Ts) mutation, is herein described as also being temperature sensitive for group I RNA phages (MS2, f2, and R17) but not for Q beta. Temperature shift experiments showed that the growth of group I phage MS2 in the mutant could be inhibited by a post-penetration event at high temperature. A possible role for the traD cistron of sex factor F in the intracellular development of MS2 is suggested.
摘要
本文描述了携带traD（Ts）突变的温度敏感型接合转移缺陷型突变体大肠杆菌JCFL39，它对I组RNA噬菌体（MS2、f2和R17）也具有温度敏感性，但对Qβ不敏感。温度转换实验表明，高温下的穿透后事件可抑制I组噬菌体MS2在该突变体中的生长。这表明性因子F的traD顺反子在MS2的细胞内发育中可能发挥作用。
