Etude de l'implantation épiphylle de Xanthomonas campestris pv. corylina, X. campestris pv. juglandis, Erwinia herbicola et Pseudomonas paucimobilis sur feuilles de noisetier

Biological role of xanthomonadin pigments in Xanthomonas campestris pv. campestris.

Previous studies have indicated that the yellow pigments (xanthomonadins) produced by phytopathogenic Xanthomonas bacteria are unimportant during pathogenesis but may be important for protection against photobiological damage. We used a Xanthomonas campestris pv. campestris parent strain, single-site transposon insertion mutant strains, and chromosomally restored mutant strains to define the bi...

Genome Sequence of Xanthomonas campestris pv. campestris Strain Xca5

An annotated high-quality draft genome sequence for Xanthomonas campestris pv. campestris race 1 strain Xca5 (originally described as X. campestris pv. armoraciae), the causal agent of black rot on Brassicaceae plants, has been determined. This genome sequence is a valuable resource for comparative genomics within the campestris pathovar.

Bactericidal activity of glycinecin A, a bacteriocin derived from Xanthomonas campestris pv. glycines, on phytopathogenic Xanthomonas campestris pv. vesicatoria cells.

The ability of glycinecin A, a bacteriocin derived from Xanthomonas campestris pv. glycines 8ra, to kill closely related bacteria has been demonstrated previously by our group. In the present study, we aimed at determining the glycinecin A-induced cause of death. Treatment with glycinecin A caused slow dissipation of membrane potential and rapid depletion of the pH gradient. Glycinecin A treatm...

Walnut Blight: Genetic Variation in English Walnut in Response to Inoculation with Xanthomonas Campestris Pv. Juglandis

This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...
