Query: NC_014816:545441 Asticcacaulis excentricus CB 48 chromosome 1, complete sequence
Lineage: Asticcacaulis excentricus; Asticcacaulis; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Environment: Fresh water; Isolation: Pondwater; Temp: Mesophile; Isolation: pond water. Asticcacaulis excentricus inhabits aquatic environments and plays an important part in biogeochemical cycling of organic nutrients. This bacterium undergoes an unusual developmental cycle in which a swarming motile cell becomes a stalked cell that is attached to a solid surface. The stalked cell then undergoes asymmetric cell division and produces one flagellated motile daughter cell and one stalked daughter cell. Thus, the asymmetric processes in this organism provide useful models for differentiation and development.
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.
