Derepression of alkaline phosphatase in Hfr of Escherichia coli during conjugation

  • P. N. Bhavsar
  • O. Siddiqi


In a mating mixture of Hfr and F- bacteria the gene for alkaline phosphatase undergoes a transient derepression at the time of transfer. It is shown that this escape from repression occurs in the donor cells and is probably connected with the synchronous duplication of the transferred genome.
