Query: NC_009937:4768500 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_008209:695269 Roseobacter denitrificans OCh 114, complete genome
Lineage: Roseobacter denitrificans; Roseobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: The aerobic phototrophic bacteria are ubiquitous as plant symbionts, free-living in lakes and ocean surface waters, soils and even near deep sea hydrothermal vents. Marine bacterium capable of aerobic anoxygenic photosynthesis. This bacterium was first isolated from a marine sediment collected on the coast of Australia. This organism's PufC photosynthetic protein has been studied as a classical tetraheme cytochrome, as it has all four possible heme-binding motifs.
