Query: NC_007794:2839239 Novosphingobium aromaticivorans DSM 12444, complete genome
Lineage: Novosphingobium aromaticivorans; Novosphingobium; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: This strain, also known as F199, was isolated from a sample obtained at a depth of 410 m from a borehole sample that was drilled at the Savannah River Site in South Carolina, USA. Aromatic hydrocarbon-degrading bacterium. This organism is unusual in that it has glycosphingolipid in the cell envelope instead of the lipopolysaccharide found in most other gram negative organisms. It is typically isolated from a wide range of environmental sites.
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.
