Pathogenicity Genes of Xanthomonas Campestris

1987
Following mutagenesis, strains of Xanthomonas campestris pv. campestris showing altered pathogenicity were isolated by screening on turnip seedlings. The mutants grew normally on laboratory media. A “library” of wild-type X. c. campestris DNA was prepared using a broad host range cloning vector (pLAFRl) and recombinant plasmids were identified which ...

Structure of the extracellular polysaccharide from xanthomonas campestris

Carbohydrate Research, 1975
Abstract Xanthan gum, the extracellular polysaccharide from Xanthomonas campestris , has been reinvestigated by methylation analysis, and by uronic acid degradation followed by oxidation and elimination of the oxidized residue. The polysaccharide is composed of pentasaccharide repeating-units with the following structure:

Биосинтеза на ксантан от Xanthomonas campestris

Biotechnology & Bioindustry, 1987
РЕЗЮМЕИсследованы 15 штаммов вида Xanthomonas campestris (Pammel) Dowson относительно выхода внеклеточного продуцированного ксантана на среде с 2-процентной сахарозой. Штаммы были разделены на три группы: слабопродуктивные (с выходом до 1,1 g/dm3), среднепродуктивные (с выходом от 2,0 до 3,8 g/dm3) и высокопродуктивные (с выходом от 4,3 до 7,5 g/dm3 ...

Evidence for clustered pathogenicity genes in Xanthomonas campestris pv. campestris

Molecular and General Genetics MGG, 1985
Plasmid pIJ3000 contains DNA from the plant pathogen Xanthomonas campestris pv. campestris which restores symptom production to a non-pathogenic mutant. pIJ3000 was mutagenised with the kanamycin resistance transposon Tn5 in Escherichia coli, and the sites of insertion were mapped physically. Derivatives of pIJ3000 containing Tn5 inserted in X.

Culture fluorescence dynamics in Xanthomonas campestris

Process Biochemistry, 2001
Abstract Culture (NAD(P)H) fluorescence dynamics have been used to provide information on culture behaviour when Xanthomonas campestris was grown in a bioreactor. Culture fluorescence decreased by 1150 units in response to an increase in extracellular pH from 3.1 to 7.6. A mathematical model incorporating the effect of pH on the bulk NADH depletion

Xanthomonas campestris pv. campestris regulates virulence mechanisms by sensing blue light

Photochemical & Photobiological Sciences
Light is an environmental stimulus to which all living organisms are exposed. Numerous studies have shown that bacteria can modulate virulence factors through photoreceptor proteins. Xanthomonas campestris pv. campestris (Xcc) is the causative agent of the systemic vascular disease black rot, which affects cruciferous crops worldwide.

Xanthomonas campestris pv. campestris (black rot).

2021
Abstract Black rot is considered the most important worldwide disease of crucifers. The disease is known to exist in the cool coastal climates of northern Europe and North America but was seldom a problem there until the 1990s. Its potential for crop damage is also considered low in New Zealand, and parts of Australia.

2019
The ethylene synthesize ability and fatty acid composition of cell lipids of collection and isolated from the diseased rape plants strains of pathogenic bacteria of the genus Xanthomonas have been investigated. It has been shown that the fatty acid spectrum of cell lipids is an important marker for identification of the rape roots bacteriosis agent ...
