Query: NC_003902:1858349 Xanthomonas campestris pv. campestris str. ATCC 33913, complete
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This strain was originally isolated from cabbage. Causes black rot disease in crucifers. This genus consists of plant-specific yellow-pigmented microbes, some of which are economically important phytopathogens that devastate crops such as citrus plants, rice, beans, grape, and cotton. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. This species is a major cause of black rot in crucifers, a disease that results in massive tissue degeneration. It also produces an extracellular polysaccharide known as xanthan, which is harvested commercially as a food stabilizing agent for use in industry.
Subject: NC_007005:98488 Pseudomonas syringae pv. syringae B728a, complete genome
Lineage: Pseudomonas syringae; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This strain is the causal agent of brown spot disease on beans. It was isolated from a snap bean leaflet in Wisconsin, USA. Plant pathogen. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This species includes many plant pathogens of important crops, which makes it a model organism in plant pathology. Its natural environment is on the surface of plant leaves and it can withstand various stressful conditions, like rain, wind, UV radiation and drought. It can colonize plants in a non-pathogenic state and can rapidly take advantage of changing environmental conditions to induce disease in susceptible plants by shifting gene expression patterns.
