It is well known that the type III secretion system (T3SS) and type III (T3) effectors are essential for the pathogenicity of most bacterial phytopathogens and that the expression of T3SS and T3 effectors is suppressed in rich media but induced in minimal media and plants. To facilitate in-depth studies on T3SS and T3 effectors, it is crucial to establish a medium for T3 effector expression and...
The O-specific polysaccharides of Xanthomonas campestris pv. vignicola GSPB 2795 and GSPB 2796 were studied by sugar and methylation analyses, Smith degradation, ID, 2D 1H and 13C NMR spectroscopy. It was found that the polysaccharides are similar branched D-rhamnans lacking strict regularity, and their structures can be described as follows: [carbohydrate equation: see text] where Rha(v) is pr...
We report the draft genome sequence of the flagellated strain CFBP 4884 of Xanthomonas fuscans subsp. fuscans, which was isolated in an outbreak of common bacterial blight of beans along with non-flagellated strains. Comparative genomics will allow one to decipher the genomic diversity of strains cohabiting in epidemics.
After completing a three-year (1995-97) evaluation of bell pepper cultivars under induced bacterial spot (Xanthomonas campestris pv. vesicatoria or Xcv) and bacterial spot-free environments, we began a new series of trials in 2000 to compare new cultivars with previously recommended cultivars that were either highly resistant (‘Boynton Bell’) and/or that had very attractive fruits (‘X3R Wizard’...
Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis DW3F3, a strong pathogenic strain isolated from blighted walnut immature fruit (Juglans regia L. cv. Qingxiang). The genome consists of a single chromosome (5,144 kb).
Here, we report the draft genome sequence of Xanthomonas arboricola pv. juglandis J303, isolated from infected walnut trees in southern Chile. The size of the genome is 5,066,424 bp with a G+C content of 65.4%. X. arboricola pv. juglandis J303 has several genes related to virulence, antibiotic resistance, and copper resistance.
Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis 417, a copper-resistant strain isolated from a blighted walnut fruit (Juglans regia L. cv. Chandler). The genome consists of a single chromosome (5,218 kb).
The genomic sequence was determined for Xanthomonas axonopodis pv. glycines strain 12609, isolated in Taiwan. Based on the genome sequence, we predicted the encoded genes, rRNA, tRNA, a plasmid sequence, secretion systems, cyclic GMP- and cyclic di-GMP-mediated pathways, and the gene cluster rpfABCHGDE (regulation of pathogenicity factor).
The plant-pathogenic bacterium Xanthomonas citri subsp. citri is the causal agent of Asiatic citrus canker, a serious disease that affects all the cultivars of citrus in subtropical citrus-producing areas worldwide. There is no curative treatment for citrus canker; thus, the eradication of infected plants constitutes the only effective control of the spread of X. citri subsp. citri. Since the e...
شانکر باکتریایی مرکبات با عامل xanthomonas citri subsp. citri، یکی از مهم ترین بیماری های مرکبات در مناطق گرمسیر و نیمه گرمسیر محسوب می شود. تجمع پروتئین های مرتبط با بیماری زایی مانند بتا 1و 3 گلوکاناز در اثر حمله عوامل بیمارگر گیاهی، از جمله مکانیسم های دفاعی گیاهان علیه عوامل بیماری زا به شمار می رود. به منظور بررسی بیان ژن pr-2 مرتبط با آنزیم بتا 1و 3 گلوکاناز و نیز فعالیت آنزیم های مؤثر در...
