Abstract
Mutants of the R factor R100 have been isolated that mediate high-frequency transfer of the R factor during conjugation. Complementation tests revealed two classes of mutants, operator-constitutive and repressor-negative. Some of the latter class were suppressible by amber and ochre suppressors. The results support a simple model of regulation for the control of R-factor-mediated piliation.
摘要
已分离出R因子R100的突变体，这些突变体在接合过程中介导R因子的高频转移。互补试验揭示了两类突变体，即操纵子组成型突变体和阻遏物阴性突变体。后一类中的一些突变体可被琥珀突变和赭石突变抑制基因所抑制。这些结果支持了一个控制R因子介导菌毛形成的简单调控模型。
