background and objective : the genus xanthomonas is composed of phytopathogenic bacterial species. in addition to causing crops diseases, most of the xanthomonas species especially xanthomonas campestris produce xanthan gum via an aerobic fermentation process. xanthan gum is, an important exopolysaccharide from xanthomonas campestris, mainly used in the food, petroleum and other industries. the...

Xanthomonas vesicatoria, Xanthomonas euvesicatoria, and Xanthomonas gardneri cause bacterial spot disease. Copper has been applied since the 1920s as part of integrated management programs. The first copper-resistant strains were reported some decades later. Here, we fully sequenced six Xanthomonas strains pathogenic to tomato and/or pepper and having a copper-resistant phenotype.

The phytopathogenic genus Xanthomonas comprises numerous species and pathovars described primarily on their host and tissue specificities. Stenotrophomonas maltophilia , which is non-phytopathogenic and taxonomically closely related to Xanthomonas , has undergone several classifications from Pseudomonas to Xanthomonas and finally to Stenotrophomonas . In this study, we have investigated the phy...

De Ley, J. (State University, Ghent, Belgium), and S. Friedman. Similarity of Xanthomonas and Pseudomonas deoxyribonucleic acid. J. Bacteriol. 89:1306-1309. 1965.-Pronounced deoxyribonucleic acid (DNA) hybridization was detected with the DNA-agar method within the group of Xanthomonas and between Xanthomonas and Pseudomonas. Sheared, denatured C(14)-DNA from X. pelargonii hybridized 80 to 100% ...

Xanthomonas arboricola pv. fragariae was described in 2001 as the causal agent of strawberry bacterial leaf blight. We report here the first draft whole-genome sequences of five X. arboricola pv. fragariae isolates from Italy and France.

We report the annotated genome sequence of Xanthomonas arboricola pv. pruni strain Xap33, isolated from almond leaves showing bacterial spot disease symptoms in Spain. The availability of this genome sequence will aid our understanding of the infection mechanism of this bacterium as well as its relationship to other species of the same genus.

Here, we report the draft genome sequence of Xanthomonas campestris LMG 8031, for which nearly no genetic information is available, despite its good xanthan-producing properties. We performed an Illumina-based sequencing approach of LMG 8031. The genome revealed a 5.0-Mb chromosome having 4,434 coding sequences and a G+C content of 65%.

Citrus canker is a citrus disease species that created by the bacterium Xanthomonas citri subsp.citri. Many citrus, such as oranges, lime, and grapefruit are affected by the infectious bacteria and stems, leaves and fruits are experiencing loss. In this experiment antibacterial effects of five kinds of antibiotics including ampicillin, kanamycin, chloramphenicol, penicillin, streptomycin, Crono...
