Abstract
In matings between F' donors and recombination-deficient Hfr recipients, we isolated progeny which transferred both episomal markers and Hfr markers early and with high frequency. A number of these progeny had two integrated sex factors. Investigation of these double Hfr strains showed that the F' nearly always integrated in a homologous region of the chromosome. In any particular mating system integration was specific as to location and direction of chromosome transfer.
摘要
在F'供体与重组缺陷型Hfr受体之间的交配中，我们分离出了早期高频转移附加体标记和Hfr标记的后代。其中一些后代有两个整合的性因子。对这些双Hfr菌株的研究表明，F'几乎总是整合在染色体的同源区域。在任何特定的交配系统中，整合在染色体转移的位置和方向上都是特异性的。
