Query: NC_009937:958576 Azorhizobium caulinodans ORS 571, complete genome
Lineage: Azorhizobium caulinodans; Azorhizobium; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This species is a stem-nodulating nitrogen-fixing organism isolated from Sesbania rostrata. Azorhizobium caulinodans ORS571 is a microsymbiont of the water-tolerant tropical legume Sesbania rostrata.A. caulinodans ORS571 is able to fix nitrogen in the free-living state, which is not the case for most rhizobia.
Subject: NC_007577:353755 Prochlorococcus marinus str. MIT 9312, complete genome
Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria
General Information: This strain was isolated by flow cytometry from water collected from the Gulf Stream in the north Atlantic Ocean. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.
