Abstract
As first recognized by Jacob, Brenner, and Cuzin (13), a successful plasmid must have an efficient replication control system that ensures its stable maintenance by the host. It is now very apparent that bacterial plasmids have evolved an intriguing variety of regulatory strategies to accomplish this (23). However, it is important to realize that for any such system to work effectively, there are certain requirements which concern the plasmid-host interaction. (i) Plasmid genes for replication control must be expressed adequately by the host at the proper time in the cell cycle. (ii) For initiation of replication, the plasmid initiation complex must interact productively with the host’s replication apparatus. (iii) Expression of the plasmid replication determinants must be tightly controlled to prevent an unnecessary metabolic burden or potentially lethal titration of host replication components. (iv) The plasmid must interact with host cell components to guarantee segregation of at least one plasmid copy to each daughter cell at division.
