Abstract
Bacteria belonging to the Rhizobiaceae have more than a century now attracted scientific attention due to their ability to associate with plants and drastically affect plant development or well-being. Major role in the plant – microbe exchange that acts in host benefit or disease is played by indigenous plasmids of the bacteria, usually large in size and mobile among members of the same family or even order. Plasmids as such can be seen as a horizontally shared genetic pool that adds to the core genome of bacterial recipients and leads to an exchange of traits that promotes intricacy in plant–microbe interactions. Moreover, key functions on these replicons are prone to induction by plant–host or bacterial community signals. In this chapter reviewed are the plasmids of the Rhizobiaceae that mediate in interbacterial or transkingdom communication, particularly in light of the most recent advancements in the genomics field.
