Abstract excerpt

We demonstrate for the first time that the broad-host-range stabilization loci from plasmid RK2 cause total retention of plasmids in cells of Rhizobium meliloti during symbiosis with alfalfa. Two derivatives of plasmid RK2, pRK290 and a 7.3-kb mini-RK2 plasmid, were stabilized in R. meliloti cell...
