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...
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...
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...
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...
Anthocyanin Accumulation in Muscadine Berry Skins Is Influenced by the Expression of the MYB Transcription Factors, MybA1, and MYBCS1
The skin color of grape berry is very important in the wine industry. The red color results from the synthesis and accumulation of anthocyanins, which is regulated by transcription factors belongin...
Application of competitive enzyme-linked immunosorbent assay for the quantification of imidacloprid titers in xylem fluid extracted from grapevines
A competitive enzyme-linked immunosorbent assay (ELISA) technique was evaluated for quantifying titers of imidacloprid in xylem fluid extracted from Vitis vinifera L. grapevines that were treated w...
A Survey of Sharpshooters (Hemiptera: Cicadellidae) in Virginia Vineyards, a Region of Expanding Concern for Pierce's Disease
A survey was conducted during the 2006 and 2007 growing seasons to record the presence of sharpshooters (Hemiptera: Cicadellidae) vectors of Pierce's disease in Vitis vinifera L. growing regions of...
Biocontrol of Pierce's disease of grapevine and citrus greening with a benign strain of Xylella fastidiosa
Vascular diseases caused by xylem-limited Xylella fastidiosa subspp. and phloem-limited Candidatus Liberibacter spp. result in large economic losses in many agricultural plants. X. fastidiosa is ra...
Biological and genetic factors regulating natural competence in a bacterial plant pathogen
For naturally competent bacteria, spatially structured growth can provide an environment for enhanced horizontal gene transfer through transformation and recombination. DNA is often present in the ...
Biological traits of Xylella fastidiosa strains from grapes and almonds
Xylella fastidiosa is a xylem-limited bacterium that causes various diseases, among them Pierce's disease of grapevine (PD) and almond leaf scorch (ALS). PD and ALS have long been considered to be ...
Cell-cell signaling controls Xylella fastidiosa interactions with both insects and plants
Xylella fastidiosa, which causes Pierce's disease of grapevine and other important plant diseases, is a xylem-limited bacterium that depends on insect vectors for transmission. Although many studie...
