A Conjugative 38 kB Plasmid Is Present in Multiple Subspecies of Xylella fastidiosa

A similar to 38kB plasmid (pXF-RIV5) was present in the Riv5 strain of Xylella fastidiosa subsp. multiplex isolated from ornamental plum in southern California. The complete nucleotide sequence of ...

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-...

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 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...

BACTERIAL DISEASES THAT MAY OR DO EMERGE, WITH (POSSIBLE) ECONOMIC DAMAGE FOR EUROPE AND THE MEDITERRANEAN BASIN: NOTES ON EPIDEMIOLOGY, RISKS, PREVENTION AND MANAGEMENT ON FIRST OCCURRENCE

Bacterial diseases are difficult to control (both chemically and biologically), and are restrained primarily by preventive measures. Most important risk factors for the introduction or spread of ba...

Calcium Increases Xylella fastidiosa Surface Attachment, Biofilm Formation, and Twitching Motility

Xylella fastidiosa is a plant-pathogenic bacterium that forms biofilms inside xylem vessels, a process thought to be influenced by the chemical composition of xylem sap. In this work, the effect of...

Citrus genomics

Citrus fruits (sweet orange, mandarin, pummelo, grapefruit, lemon, lime and assorted hybrids) are among the most widely grown and economically important fruit tree crops in the world. As fresh frui...

Detecting Genetic Introgression: High Levels of Intersubspecific Recombination Found in Xylella fastidiosa in Brazil

Documenting the role of novel mutation versus homologous recombination in bacterial evolution, and especially in the invasion of new hosts, is central to understanding the long-term dynamics of pat...

Differentiation of Xylella fastidiosa Strains via Multilocus Sequence Analysis of Environmentally Mediated Genes (MLSA-E)

Isolates of the plant pathogen Xylella fastidiosa are genetically very similar, but studies on their biological traits have indicated differences in virulence and infection symptomatology. Taxonomi...

Disrupting the Transmission of a Vector-Borne Plant Pathogen

Approaches to control vector-borne diseases rarely focus on the interface between vector and microbial pathogen, but strategies aimed at disrupting the interactions required for transmission may le...

EFFECT OF CONTACT AND SYSTEMIC INSECTICIDES ON THE SHARPSHOOTER BUCEPHALOGONIA XANTHOPHIS (HEMIPTERA: CICADELLIDAE), A VECTOR OF XYLELLA FASTIDIOSA IN CITRUS

The knockdown and toxic effects of insecticides of different chemical groups and modes of action registered for citrus in Brazil were investigated for effective control of Bucephalogonia xanthophis...
