Abstract

Several strains of Escherichia coli K-12 harboring two F factors were isolated from Hfr x Hfr crosses. These strains were transiently capable of initiating chromosome transfer from two separate points of origin, and of transferring two different sex factors as integrated chromosomal markers. Each strain tested invariably reverted to a simple Hfr by loss of one of the inherited F factors. The F factor persisting in the revertant was, in nearly every case, that which had been inherited from the recipient Hfr parent.

摘要

从高频重组(Hfr)×高频重组(Hfr)杂交中分离出了几株携带两个F因子的大肠杆菌K-12菌株。这些菌株能够短暂地从两个不同的起始点启动染色体转移,并作为整合的染色体标记转移两种不同的性因子。每个测试菌株总是通过丢失其中一个遗传的F因子而回复为简单的高频重组(Hfr)。在几乎所有情况下,回复体中持续存在的F因子是从受体高频重组(Hfr)亲本遗传而来的那个。
