Abstract

SUMMARY: Colicine factors I and E1 enable , like , to pair at high frequency (e.g. with 50-90 % of recipient cells) either with its own derivatives or with those of other species such as and However, genetic recombinants occur at only low frequency in intraspecific crosses (about 10 of recipient cells); whereas in interspecific crosses with as donor, recombination with involving either closely linked or single markers occurred at an even lower frequency (about 10 of recipient cells). No detectable recombinants were isolated when using either or as donor and as recipient, although colicine factors were transferred at high frequency.
