Query: NC_004463:1749000 Bradyrhizobium japonicum USDA 110, complete genome
Lineage: Bradyrhizobium diazoefficiens; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain was isolated from Glycine hispida in 1959 in Florida, USA, and has been widely studied because of its superior symbiotic nitrogen fixation with soybeans as compared to other strains. This strain contains a 681 Kb symbiosis island that contains genes for nitrogen fixation and root nodule formation. The chromosome also contains genes resembling those of type III and IV secretion systems.
Subject: NC_007761:3047321 Rhizobium etli CFN 42, complete genome
Lineage: Rhizobium etli; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: It is a nitrogen-fixing symbiotic bacteria that interacts with the root of the common bean plant Phaseolus vulgaris. P. etli and its relation to other nitrogen/fixing symbionts has been well studied. The genomic sequence will provide information on the process of symbiosis, on the genetic systems that allow the survival and adaptations of this bacteria to the soil, and on the evolutionary relationship and the symbiosis origin of this organism.
