Effect of Zn2+ on bacterial conjugation: increase in ability of F- cells to form mating pairs.
Incubation of F(-) cells at 37 C with 10(-3) M Zn(2+) 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 Zn(2+) treatment can form mating pairs efficiently with males from which F pili were removed or inactivated with 10(-3) M Zn(2+).
