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 ...
An engineered innate immune defense protects grapevines from Pierce disease
We postulated that a synergistic combination of two innate immune functions, pathogen surface recognition and lysis, in a protein chimera would lead to a robust class of engineered antimicrobial th...
A novel protein refolding protocol for the solubilization and purification of recombinant peptidoglycan-associated lipoprotein from Xylella fastidiosa overexpressed in Escherichia coli
Xylella fastidiosa is a Gram-negative xylem-limited plant pathogenic bacterium responsible for several economically important crop diseases. Here, we present a novel and efficient protein refolding...
A Simple Defined Medium for the Production of True Diketopiperazines in Xylella fastidiosa and Their Identification by Ultra-Fast Liquid Chromatography-Electrospray Ionization Ion Trap Mass Spectrometry
Diketopiperazines can be generated by non-enzymatic cyclization of linear dipeptides at extreme temperature or pH, and the complex medium used to culture bacteria and fungi including phytone pepton...
Expression of putative pathogenicity-related genes in Xylella fastidiosa grown at low and high cell density conditions in vitro
Xylella fastidiosa is the causal agent of economically important plant diseases, including citrus variegated chlorosis and Pierce's disease. Hitherto, there has been no information on the molecular...
EXTRACELLULAR GENOMIC DNA MEDIATES ENHANCEMENT OF XYLELLA FASTIDIOSA BIOFILM FORMATION IN VITRO
Xylella fastidiosa (Xf) produces extracellular DNA in PD3 liquid medium. This extracellular DNA could enhance biofilm formation, a factor in successful establishment of Xf in planta. The relative a...
Genome sequence of Xanthomonas fuscans subsp fuscans strain 4834-R reveals that flagellar motility is not a general feature of xanthomonads
Xanthomonads are plant-associated bacteria responsible for diseases on economically important crops. Xanthomonas fuscans subsp. fuscans (Xff) is one of the causal agents of common bacterial blight ...
Genomic insights into strategies used by Xanthomonas albilineans with its reduced artillery to spread within sugarcane xylem vessels
Background: Xanthomonas albilineans causes leaf scald, a lethal disease of sugarcane. X. albilineans exhibits distinctive pathogenic mechanisms, ecology and taxonomy compared to other species of Xa...
In vitro Determination of Extracellular Proteins from Xylella fastidiosa
The phytopathogen Xylella fastidiosa causes economic losses in important agricultural crops. Xylem vessel occlusion caused by biofilm formation is the major mechanism underlying the pathogenicity o...
Localization and characterization of Xylella fastidiosa haemagglutinin adhesins
Xylella fastidiosa is a Gram-negative, xylem-inhabiting, plant-pathogenic bacterium responsible for several important diseases including Pierce's disease (PD) of grapevines. The bacteria form biofi...
Regulation of resistance to copper in Xanthomonas axonopodis pv. vesicatoria
Copper-resistant strains of Xanthomonas axonopodis pv. vesicatoria were previously shown to carry plasmid-borne copper resistance genes related to the cop and pco operons of Pseudomonas syringae an...
Stable transformation of the Xylella fastidiosa citrus variegated chlorosis strain with oriC plasmids
Xylella fastidiosa is a gram-negative, xylem-limited bacterium affecting economically important crops (e,g,, grapevine, citrus, and coffee). The citrus variegated chlorosis (CVC) strain of X. fasti...
