Query: NC_004463:2158116 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_000914:135534 Rhizobium sp. NGR234 plasmid pNGR234a, complete sequence
Lineage: Sinorhizobium fredii; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Sinorhizobium fredii NGR234 NGR234 is unusual in that it is able to form nodules on the roots of more than 112 plants. This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, such as soybean, cowpea or pigeon pea. Expression of nodulation genes results in production of a nodulation signal which the plant cell recognizes inducing root nodule formation. The plant cell provides carbon compounds for the bacterium to grow on.
