Pseudomonas viridiflava causes foliar and stem necrosis, as well as stem and root rot on a wide range of plants. We report here the first complete genome of a P. viridiflava strain, isolated from diseased tissue of a cherry tree.

The production of peptide siderophores and the variation in siderophore production among strains of Pseudomonas syringae and Pseudomonas viridiflava were investigated. An antibiose test was used to select a free amino acid-containing agar medium favorable for production of fluorescent siderophores by two P. syringae strains. A culture technique in which both liquid and solid asparagine-containi...

The contribution of arms race dynamics to plant-pathogen coevolution has been called into question by the presence of balanced polymorphisms in resistance genes of Arabidopsis thaliana, but less is known about the pathogen side of the interaction. Here we investigate structural polymorphism in pathogenicity islands (PAIs) in Pseudomonas viridiflava, a prevalent bacterial pathogen of A. thaliana...

The pectinolytic species Pseudomonas viridiflava has a wide host range among plants, causing foliar and stem necrotic lesions and basal stem and root rots. However, little is known about the molecular evolution of this species. In this study we investigated the intraspecies genetic variation of P. viridiflava amongst local (Cretan), as well as international isolates of the pathogen. The genetic...

A virulent Pseudomonas viridiflava-related bacterium has been identified as a new pathogen of soybean, one of the most important crops worldwide. The bacterium was recovered from forage soybean leaves with dark-reddish spots, and damage on petioles and pods was also observed. In contrast, common bean was not affected.

Here, we report the draft genome sequence of Pseudomonas viridiflava strain CDRTc14 a pectinolytic bacterium showing herbicidal activity, isolated from the root of Lepidium draba L. growing as a weed in an Austrian vineyard. The availability of this genome sequence allows us to investigate the genetic basis of plant-microbe interactions.

Species-level genetic diversity and recombination in bacterial pathogens of wild plant populations have been nearly unexplored. Pseudomonas viridiflava is a common natural bacterial pathogen of Arabidopsis thaliana, for which pathogen defense genes and mechanisms are becoming increasing well known. The genetic variation contained within a worldwide sample of P. viridiflava collected from wild p...

Pseudomonas strains with an atypical LOPAT profile (where LOPAT is a series of determinative tests: L, levan production; O, oxidase production; P, pectinolitic activity; A, arginine dihydrolase production; and T, tobacco hypersensibility) can be regarded as emergent pathogens in the Principality of Asturias (Spain), where they have been causing, since 1999, severe damage in at least three taxon...
