16S-23S RDNA: Polymorphisms and their use for detection and identification of Xylella fastidiosa strains
Strains of Xylella fastidiosa from several hosts (coffee, citrus, grape, almond, oleander, peach, plum, etc.) were characterized by analyzing the content of the nucleotide sequences of 16S- 23S rDN...
A cell-cell signaling sensor is required for virulence and insect transmission of Xylella fastidiosa
Cell-cell signaling in Xylella fastidiosa, a xylem-colonizing plant pathogenic bacterium, mediated by a fatty acid Diffusible Signaling Factor (DSF), is required to colonize insect vectors and to s...
A chitinase is required for Xylella fastidiosa colonization of its insect and plant hosts
Xylella fastidiosa colonizes the xylem network of host plant species as well as the foregut of its required insect vectors to ensure efficient propagation. Disease management strategies remain inef...
A high-molecular-weight outer membrane protein of Xanthomonas oryzae pv. oryzae exhibits similarity to non-fimbrial adhesins of animal pathogenic bacteria and is required for optimum virulence
Transposon insertions in a novel 3.798 kb open reading frame (ORF) of the rice pathogen, Xanthomonas oryzae pv. oryzae (Xoo) cause virulence deficiency and altered colony/lawn morphology. This ORF ...
A MotN Mutant of Ralstonia solanacearum Is Hypermotile and Has Reduced Virulence
Ralstonia solanacearum is a soil-borne plant pathogen that causes bacterial wilt disease on many plant species. We previously showed that swimming motility contributes to virulence of this bacteriu...
Analysis of Defense-Related Gene Expression in Citrus Hybrids Infected by Xylella fastidiosa
Resistance to Xylella fastidiosa was evaluated in 264 hybrids of crosses between Murcott tangor (Citrus reticulata x Citrus sinensis) and Pera sweet orange (C. sinensis) under field conditions. Uni...
Analysis of expressed sequence tags from Citrus sinensis L. Osbeck infected with Xylella fastidiosa
In order to understand the genetic responses resulting from physiological changes that occur in plants displaying citrus variegated chlorosis (CVC) symptoms, we adopted a strategy of comparing two ...
Analysis of resistance to Xylella fastidiosa within a hybrid population of Pera sweet orange x Murcott tangor
Resistance to Xylella fastidiosa was evaluated within a population of 20 interspecific hybrids of Pera sweet orange and Murcott tangor under greenhouse conditions. Efficiency of inoculation, multip...
Analysis of the biofilm proteome of Xylella fastidiosa
Xylella fastidiosa is limited to the xylem of the plant host and the foregut of insect vectors (sharpshooters). The mechanism of pathogenicity of this bacterium differs from other plant pathogens, ...
A nested-PCR assay for detection of Xylella fastidiosa in citrus plants and sharpshooter leafhoppers
Detection of Xylella fastidiosa in citrus plants and insect vectors. Chelex 100 resin matrix was successfully standardized allowing a fast DNA extraction of X. fastidiosa. An amplicon of 500 bp wa...
A new regulatory DNA motif of the gamma subclass proteobacteria: identification of the LexA protein binding site of the plant pathogen Xylella fastidiiosa
Escherichia coli LexA protein is the repressor of a gene network whose members are directly involved in the repair of damaged DNA and in the survival of bacterial cells until DNA lesions have been ...
Anterior Foregut Microbiota of the Glassy-Winged Sharpshooter Explored Using Deep 16S rRNA Gene Sequencing from Individual Insects
The glassy-winged sharpshooter (GWSS) is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidi...
