Lineage: Liberibacter solanacearum; Liberibacter; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This unculturable bacterium causes Zebra Chip disease of potato. The bacterium was identified in 2008 and named as "Candidatus Liberibacter solanacearum" The disease causes million dollar loss in U.S. potato industry. Liberibacters are phloem-limited bacteria that are spread from infected to healthy plants. The species epithet 'solanacearum' refers to the family of plant hosts found to contain these organisms.
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.
