Query: NC_012587:3177583 Rhizobium sp. NGR234, complete genome
Lineage: Sinorhizobium fredii; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: 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.
Subject: NC_008340:362000 Alkalilimnicola ehrlichei MLHE-1, complete genome
Lineage: Alkalilimnicola ehrlichii; Alkalilimnicola; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria
General Information: This chemoautotrophic strain was isolated from Mono Lake in California, which contains arsenic and has high pH and salt concentrations. Arsenite-oxidizing bacterium. Alkalilimnicola ehrlichei is capable of growth with arsenite [As(III)] as the electron donor with nitrate as electron acceptor. It may be responsible for production of arsenate [As(V)] in anoxic lake bottom.
