Query: NC_008209:1097607 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.
Subject: NC_010125:74904 Gluconacetobacter diazotrophicus PAl 5, complete genome
Lineage: Gluconacetobacter diazotrophicus; Gluconacetobacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Gluconacetobacter diazotrophicus strain PAL5 (ATCC 49037) was isolated from sugarcane roots in Brazil and will be used for comparative analysis. Nitrogen-fixing plant symbiont. This acid-tolerant organism is endophytic and colonizes internal plant tissues, establishing a symbiotic relationship with its host. This bacterium has been found in sugarcane, coffee, rice, tea, and other plants. The nitrogen-fixation systems of the bacterium provide the plant with essential nitrogenous compounds while the plant provides a protected environment for the bacterium to grow in. Nitrogen-fixation is important for sugarcane production, and this organism can fix nitrogen even in the presence of nitrate.
