Abstract

Wild-type R plasmids of the P1 incompatibility group mediated the transfer of chromosomal genes in , but only at very low frequencies. Two P1 R plasmids, which had originally been selected in for enhanced donor properties, promoted much higher levels of gene transfer in . One of these, R68.45, was used for linkage mapping. All markers tested mapped on a single circular linkage group. Segments of donor chromosome up to at least one-seventh of its total length were transferred and integrated into the recipient chromosome.
