Query: NC_012587:1181004 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_012796:3600630 Desulfovibrio magneticus RS-1, complete genome
Lineage: Desulfovibrio magneticus; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Isolated from freshwater sulfide-rich mud of a waterway near Kameno river, Wakayama, in Japan. This organism is a sulfate-reducing delta proteobacterium which synthesizes intracellular magnetite particles. Desulfovibrio magneticus produces irregular, membrane-bound magnetite particles, unlike other magnetite-producing bacteria which contain crystalline magnetite in the cytoplasm. Desulfovibrio magneticus does not migrate along a magnetic field but swims randomly.
