The RepA and RepB autorepressors and TraR play opposing roles in the regulation of a Ti plasmid repABC operon

Summary The replicator regions of the Ti plasmids of Agrobacterium tumefaciens belong to the repABC family of replication and partitioning systems, members of which are widely distributed among alpha proteobacteria. In the region upstream of the octopine‐type Ti plasmid repABC operon, three promoter...
