Three related F'arg+ plasmids isolated by Guyer and Clark were used to analyze some properties of strain MG751, a recipient derivative of an HfrC mutant (MG7) carrying a previously described pleiotropic mutation in the integrated F plasmid. Strains MG7 and MG751 both failed to produce recombination-stimulating factor, were sensitive to monofunctional alkylating agents and UV irradiation, and were temperature sensitive for growth and DNA synthesis. It was shown that these phenotypes are controlled by F plasmids genes (designated rsf, prt, and rep) that can be separated by deletion mutations occurring on the F plasmid.
盖耶尔和克拉克分离出的三种相关的F'arg+质粒被用于分析菌株MG751的一些特性,MG751是HfrC突变体(MG7)的受体衍生物,其整合的F质粒中携带一个先前描述的多效性突变。菌株MG7和MG751都不能产生重组刺激因子,对单功能烷化剂和紫外线照射敏感,并且对生长和DNA合成具有温度敏感性。结果表明,这些表型由F质粒基因(命名为rsf、prt和rep)控制,这些基因可通过F质粒上发生的缺失突变而分离。
