Query: NC_007643:889755 Rhodospirillum rubrum ATCC 11170, complete genome
Lineage: Rhodospirillum rubrum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: This bacterium can grow using carbon monoxide as the sole carbon and energy source and the cells contain a well characterized nitrogenase system that is post-translationally modified by ADP-ribosylation. Phototrophic bacterium. This organism is an anoxygenic phototrophic bacterium that does not produce oxygen, but instead produces extracellular elemental sulfur when harvesting light energy. The bacterium lacks the light harvesting complex 2 (LHC2) normally found in photosynthetic bacteria meaning it contains one of the simplest photosynthetic systems studied.
Subject: NC_010577:151926 Xylella fastidiosa M23, complete genome
Lineage: Xylella fastidiosa; Xylella; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from an almond tree in California. Causal agent of citrus variegated chlorosis. This organism was first identified in 1993 as the causal agent of citrus variegated chlorosis, a disease that affects varieties of sweet oranges. Other strains of this species cause a range of diseases in mulberry, pear, almond, elm, sycamore, oak, maple, pecan and coffee which collectively result in multimillion dollar devastation of economically important plants. It does not contain a type III secretion system, but possesses genes for a type II secretion system for export of exoenzymes that degrade the plant cell wall and allow the bacterium to colonize the plant xylem. The cell produces an exopolysaccharide that is similar to the xanthan gum produced by Xanthomonas campestris pv. campestris.
