Molecular Genetic Characterization of the Mating Pair Formation and Vegetative Replication Regions on the Agrobacterium Tumefaciens Ti Plasmid pTiC58
… of several large plasmids found in the family Rhizobiaceae. The TraR recognition sites located in the traI-repA intergenic region affected expression of both traI-trb operon and repA. Copy number of a minimal rep plasmid and the Ti plasmid increased in the presence of TraR and AAI. We concluded …
