TL;DR: The genome of A. tumefaciens strain C58 is described, which has an unusual structure consisting of one circular and one linear chromosome and additional genes potentially involved in virulence and metabolic parasitism of host plants.

TL;DR: It is suggested that gene duplication and divergence were major contributors to genomic expansion from its progenitor, and families of genes encoding the production of secondary metabolites are overrepresented in the genome but may have been received by horizontal gene transfer and are likely to be important for predation.

TL;DR: The complete genome sequence of A. vinelandii DJ is reported, which identified the chromosomal locations of the genes coding for the three known oxygen-sensitive nitrogenases, as well as genes codes for other oxygen- sensitive enzymes, such as carbon monoxide dehydrogenase and formate dehydrogen enzyme.

TL;DR: Together, these results define the evolution of chromosome architecture and gene content among the Rhizobiaceae and support a generalized mechanism for second-chromosome formation among bacteria.

TL;DR: Findings indicate that evolutionary changes shaped by symbiotic interactions can follow different routes to achieve similar end points.
