resistance of cotton towards Xanthomonas campestris pv malvacearum
Annual Review of Phytopathology, 2005Co-Authors: Etienne Delannoy, B R Lyon, Philippe Marmey, Aida Jalloul, Jeanfrancois Daniel, Jeanluc Montillet, M Essenberg, Michel NicoleAbstract:Interactions between Gossypium spp. and the bacterial pathogen Xanthomonas campestris pv. malvacearum are understood in the context of the gene-for-gene concept. Reviewed here are the genetic basis for cotton resistance, with reference to resistance genes, resistance gene analogs, and bacterial avirulence genes, together with the physiological mechanisms involved in the hypersensitive response to the pathogen, including production of signaling hormones, synthesis of antimicrobial molecules and alteration of host cell structures. This host-pathogen interaction represents the most complex resistance gene/avr gene system yet known and is one of the few in which phytoalexins are known to be specifically localized in HR cells at anti-microbial concentrations.

insights into genome plasticity and pathogenicity of the plant pathogenic bacterium Xanthomonas campestris pv vesicatoria revealed by the complete genome sequence
Journal of Bacteriology, 2005Co-Authors: Frank Thieme, Thomas Bekel, Ralf Koebnik, Carolin Berger, Jens Boch, Daniela Buttner, Camila Caldana, Lars Gaigalat, Alexander Goesmann, Oliver KirchnerAbstract:The gram-negative plant-pathogenic bacterium Xanthomonas campestris pv. vesicatoria is the causative agent of bacterial spot disease in pepper and tomato plants, which leads to economically important yield losses. This pathosystem has become a well-established model for studying bacterial infection strategies. Here, we present the whole-genome sequence of the pepper-pathogenic Xanthomonas campestris pv. vesicatoria strain 85-10, which comprises a 5.17-Mb circular chromosome and four plasmids. The genome has a high G+C content (64.75%) and signatures of extensive genome plasticity. Whole-genome comparisons revealed a gene order similar to both Xanthomonas axonopodis pv. citri and Xanthomonas campestris pv. campestris and a structure completely different from Xanthomonas oryzae pv. oryzae. A total of 548 coding sequences (12.2%) are unique to X. campestris pv. vesicatoria. In addition to a type III secretion system, which is essential for pathogenicity, the genome of strain 85-10 encodes all other types of protein secretion systems described so far in gram-negative bacteria. Remarkably, one of the putative type IV secretion systems encoded on the largest plasmid is similar to the Icm/Dot systems of the human pathogens Legionella pneumophila and Coxiella burnetii. Comparisons with other completely sequenced plant pathogens predicted six novel type III effector proteins and several other virulence factors, including adhesins, cell wall-degrading enzymes, and extracellular polysaccharides.

The cloning, crystallization and preliminary X‐ray analysis of XC2113, a YaeQ protein from Xanthomonas campestris
Acta Crystallographica Section F-structural Biology and Crystallization Communications, 2006Co-Authors: Kuo-cheng Chio, Ko-hsin Chin, Andrew H.-j. Wang, Shan-ho ChouAbstract:Xanthomonas campestris is a Gram-negative bacterium that is phytopathogenic to cruciferous plants and causes worldwide agricultural loss. It is therefore important to identify potential pathogenic factors involved in this plant disease. Here, the cloning, expression, crystallization and preliminary X-ray analysis of XC2113, a YaeQ protein possibly involved in the production of virulence factors in Xanthomonas campestris pathovar campestris, are reported. The XC2113 crystals diffracted well to a resolution of at least 1.28 A. They are orthorhombic and belong to space group P212121, with unit-cell parameters a = 32.86, b = 62.69, c = 79.96 A.

Letter to the Editor: NMR structure note - Solution structure of a bacterial BolA-like protein XC975 from a plant pathogen Xanthomonas campestris pv. campestris
Journal of Biomolecular NMR, 2005Co-Authors: Ko-hsin Chin, Yu-chen Hu, Shan-ho ChouAbstract:[[abstract]]Xanthomonas campestris (XC) is a Gram-negative bacterium that is phytopathogenic to cruciferous plants and causes worldwide agricultural loss (da Silva et al., 2002). However, it also produces exopolysaccharide (xanthan gum) that is of enormous industrial importance. To identify and characterize novel protein structures and functions in Xanthomonas campestris, we have initiated a structural genomics program of a local strain Xanthomonas campestris pv. campestris 17 (Tseng et al., 1999). Its genome has been successfully sequenced using the shotgun method (P. Tsai, unpublished result, 2004) and the encoded ORFs were predicted using a bioinformatics approach.[[fileno]]2050134010023[[department]]生科
