Query: 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.
Subject: NC_011186:515214 Vibrio fischeri MJ11 chromosome II, complete sequence
Lineage: Aliivibrio fischeri; Aliivibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: This strain was isolated from a pinecone fish, Monocentris japonica, light-emitting organs in Japan. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. This organism is found in marine environments and was originally named by Bernard Fischer during a sea voyage in the 1800s. It is a symbiont in fish and squids and is responsible for light generation in those organisms, which use it as a defense mechanism to avoid predators.
