Query: NC_007426:205390 Natronomonas pharaonis DSM 2160, complete genome

Lineage: Natronomonas pharaonis; Natronomonas; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea

General Information: Isolated from Lake Gabara in Egypt. Extreme haloalkaliphilic archeon. Natronomonas pharaonis is able to survive at high salt and pH conditions which results in limited nitrogen availability through ammonium. In order to compensate for this, Natronomonas pharaonis has developed three systems to promote nitrogen assimilation: direct uptake of ammonia, uptake of nitrate, and uptake of urea. Another problem with high pH environments is the use of a proton gradient for the generation of ATP, which other alkaliphiles have adapted to by substitution of sodium ions for protons. However, this organism utilizes protons for ATP generation as determined by experimental data.

Subject: NC_003047:74986 Sinorhizobium meliloti 1021, complete genome

Lineage: Sinorhizobium meliloti; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: Streptomycin resistant derivative of strain 2011. Plant symbiotic bacterium. This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, in this case the alfalfa plant (Medicago sativa). 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.
