title: Recombinant plasmids formed in vivo carrying and expressing two incompatibility regions.
abstract: The formation in vivo of recombinants between a plasmid of incompatibility group N (R1010-10) and plasmids of groups P (R751) and W (R388) is described. From examination of the molecular weights of these recombinant plasmids, they appear to be cointegrates. These cointegrates have the incompatibility properties of both 'parent' plasmids.
