THE EXTRACELLULAR POLYSACCHARIDE OF XANTHOMONAS PHASEOLI
Canadian Journal of Biochemistry and Physiology, 1959The extracellular polysaccharide produced by Xanthomonas phaseoli has been purified and shown to be homogeneous by examination in the analytical ultra-centrifuge, by moving boundary electrophoresis, and by gradient precipitation with ethanol. Following hydrolysis the constituent sugars of the polysaccharide were isolated and positively identified as ...

The title of this chapter is not wholly accurate. Our primary purpose is not to describe Xanthomonas genetics as a topic per se but rather to illustrate the use of genetic approaches to analyse aspects of Xanthomonas biology. Most of the studies reported so far have been concerned either with phytopathogenicity or with the production of polysaccharide.

Intraspecific Variability of Xanthomonas albilineans
Systematic and Applied Microbiology, 1993Summary Sixty five Xanthomonas albilineans strains originating from 22 countries were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole-cell proteins, indirect-immunofluorescent antibody typing and gas-liquid chromatographic analysis of fatty acid methyl esters (FAMEs). The strains were separated into two major

The Genomics of Xanthomonas oryzae [PDF]
, 2014 Xanthomonas oryzae pathovars oryzae and oryzicola cause bacterial leaf blight and bacterial leaf streak of rice, respectively, two diseases that pose a significant threat to global rice yields. The first four complete genome sequences of X. oryzae strains yielded a wealth of information about virulence factor content, mobile genetic elements, and ...

Epiphytic growth of Xanthomonas arboricola and Xanthomonas citri on non‐host plants
Plant Pathology, 2017The population dynamics of Xanthomonas arboricola pv. pruni (Xap) and X. citri subsp. citri (Xcc) was assessed on over three dozen plant species/genotypes under field and greenhouse conditions. Both Xap and Xcc multiplied on red nightshade, black nightshade, bindweed, Chenopodium, common bean and wheat up to 20 days post‐inoculation (dpi) under ...

Production of xanthan gum using immobilized cells of Xanthomonas campestris and Xanthomonas pelargonii grown on glucose or hydrolyzed starch as carbon sources was investigated. Calcium alginate (CA) and calcium alginate-polyvinyl alcohol-boric acid (CA-PVA) beads were used for the immobilization of cells.

XylellaandXanthomonasMobil'omics [PDF]
OMICS: A Journal of Integrative Biology, 2005 The gamma-proteobacterium Xanthomonadales groups two closely related genera of plant pathogens, Xanthomonas and Xylella. Whole genome sequencing and comparative analyses disclosed a high degree of identity and co-linearity of the chromosome backbone between species and strains.

Management of Xanthomonas diseases
1993Effective disease control must be based on knowledge of the life cycle of the pathogen and the interaction between the pathogen and the host plant (Lozano and Wholey, 1974). The weakest link in the disease cycle, when control strategies are most effective, is during the survival phase of the pathogen.

Bacteria belonging to the genus Xanthomonas are, with the exception of X. maltophilia which is cosmopolitan in distribution and not known to be a plant pathogen (Swings et al., 1983), plant-associated bacteria and not usually encountered in other environments. They are not invariably plant pathogens. Isolates resembling X. campestris pv.

1981
The first reported observation of a phytopathogenic bacterium that nowadays would be referred to the genus Xanthomonas was made in 1881 by Wakker (1883), in the case of the yellows disease of hyacinths. In his brief initial report, Wakker recorded several salient features of the causal agent which today would alert any informed phytobacteriologist to ...
