Effect of Zn2+ on Bacterial Conjugation: Increase in Ability of F− Cells to Form Mating Pairs

Ou, Jonathan T.

RESUMO

Incubation of F− cells at 37 C with 10−3 M Zn2+ before mating was found to increase the ability of F− cells to form mating pairs when mated. This increased pair-forming ability is persistent, at least for the duration of mating. The F− cells with increased pair-forming ability obtained by the 10−3 M Zn2+ treatment can form mating pairs efficiently with males from which F pili were removed or inactivated with 10−3 M Zn2+.
