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 p...

Studies on some bacterial diseases of fruit plants from Aurangabad district was carried out during 2003-2009. They are: Leaf necrosis of Custard apple caused by Xanthomonas annonae; Citrus canker caused by Xanthomonas campestris pv. citri; Bacterial canker of Mango caused by Xanthomonas campestris pv. mangiferaeindicae; Leaf necrosis of Guava caused by Xanthomonas psidae; and leaf spot of Badam...

The phylogenetic relationships of all validly described species of the genus Xanthomonas and the type strain of Stenotrophomonas maltophilia were analyzed by sequencing and comparing 16S ribosomal DNAs (rDNAs). The two genera exhibited a mean sequence similarity value of 96.6%, corresponding to differences at 50 nucleotide positions on average. The species of the genus Xanthomonas exhibited rel...

The secondary metabolites such as essential oil and pure compounds (limonin and imperatorin) from Poncirus trifoliata Rafin were tested for in vitro control of phytopathogenic bacteria of Xanthomonas spp. In vitro studies showed that the oil had inhibitory effect on Xanthomonas campestris pv. compestris KC94-17-XCC, Xanthomonas campestris pv. vesicatoria YK93-4-XCV, Xanthomonas oryzae pv. oryza...

Scientific name: Xanthomonas axonopodis pv. allii (Roumagnac et al., 2004a,b). Synonyms: Xanthomonas campestris pv. allii (Kadota et al., 2000). Taxonomic position: Proteobacteria: Gammapropteobacteria: Xanthomonadales: Xanthomonasdaceae. Common names: Xanthomonas axonopodis pv. allii is the causal agent of onion bacterial blight (syn. Xanthomonas leaf blight of onion). EPPO code: XANTAA. Phyto...

We present draft genome sequences for three strains of Xanthomonas species, each of which was associated with banana plants (Musa species) but is not closely related to the previously sequenced banana-pathogen Xanthomonas campestris pathovar musacearum. Strain NCPPB4393 had been deposited as Xanthomonas campestris pathovar musacearum but in fact falls within the species Xanthomonas sacchari. St...

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% ...
