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...
Accumulation of Azelaic Acid in Xylella fastidiosa-Infected Olive Trees: A Mobile Metabolite for Health Screening
Monitoring Xylella fastidiosa is critical for eradicating or at least containing this harmful pathogen. New low-cost and rapid methods for early detection capability are very much needed. Metabolom...
Acquisition and Evolution of Plant Pathogenesis-Associated Gene Clusters and Candidate Determinants of Tissue-Specificity in Xanthomonas
Background: Xanthomonas is a large genus of plant-associated and plant-pathogenic bacteria. Collectively, members cause diseases on over 392 plant species. Individually, they exhibit marked host- a...
A delivery system for field application of paratransgenic control
As an alternative to chemical pesticides, paratransgenesis relies on transformation of symbiotic bacteria of an arthropod vector to deliver molecules that disrupt pathogen transmission. For over a ...
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 kinetic model for Xylella fastidiosa adhesion, biofilm formation, and virulence
Xylella fastidiosa is the causal agent of citrus variegated chlorosis and Pierce's disease which are the major threat to the citrus and wine industries. The most accepted hypothesis for Xf diseases...
Alfalfa and Pastures: Sources of Pests or Generalist Natural Enemies?
Pierce’s disease of grapevine and almond leaf scorch disease are both caused by the bacterial pathogen Xylella fastidiosaWells et al. In the Central Valley of California, Draeculacephala minerva Ba...
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...
A multigene phylogenetic study of clonal diversity and divergence in North American strains of the plant pathogen Xylella fastidiosa
Xylella fastidiosa is a pathogen that causes leaf scorch and related diseases in over 100 plant species, including Pierce's disease in grapevines (PD), phony peach disease (PP), plum leaf scald (PL...
Analysis of 16S rRNA and mxaF genes revealing insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-...
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 ...
