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 ...
A Short Protocol for Gene Knockout and Complementation in Xylella fastidiosa Shows that One of the Type IV Pilin Paralogs (PD1926) Is Needed for Twitching while Another (PD1924) Affects Pilus Number and Location
Twitching motility is one of the major virulence factors of the plantpathogenic bacterium Xylella fastidiosa, and it is mediated by type IV pili (TFP) that are present at one of the cell poles. Gen...
Ca2+-Induced Two-Component System CvsSR Regulates the Type III Secretion System and the Extracytoplasmic Function Sigma Factor AlgU in Pseudomonas syringae pv. tomato DC3000
Two-component systems (TCSs) of bacteria regulate many different aspects of the bacterial life cycle, including pathogenesis. Most TCSs remain uncharacterized, with no information about the signal(...
Detection of a Single-Copy Plasmid, pXFSL21, in Xylella fastidiosa Strain Stag's Leap with Two Toxin-Antitoxin Systems Using Next-Generation Sequencing
Plasmids are important genetic elements contributing to bacterial evolution and environmental adaptation. Xylella fastidiosa is a nutritionally fastidious Gram-negative bacterium causing economical...
Genome features of Leptospira interrogans serovar Copenhageni
We report novel features of the genome sequence of Leptospira interrogans serovar Copenhageni, a highly invasive spirochete. Leptospira species colonize a significant proportion of rodent populatio...
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...
GIS Analysis of Land-Use Change in Threatened Landscapes by Xylella fastidiosa
Land-use/land-cover analysis using Geographic Information System (GIS) application can describe and quantify the transformation of the landscape, evaluating the effectiveness of municipal planning ...
Grapevine susceptibility to Pierce's disease II: Progression of anatomical symptoms
The progression of anatomical symptoms of Pierce's disease in susceptible Vitis vinifera cv. Chardonnay grapevines was studied over a time course following controlled inoculation of Y-shaped, two-s...
Identification and analysis of seven effector protein families with different adaptive and evolutionary histories in plant-associated members of the Xanthomonadaceae
The Xanthomonadaceae family consists of species of non-pathogenic and pathogenic gamma-proteobacteria that infect different hosts, including humans and plants. In this study, we performed a compara...
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...
Local and Landscape Constraints on Coffee Leafhopper (Hemiptera: Cicadellidae) Diversity
The intensification of agriculture drives many ecological and environmental consequences including impacts on crop pest populations and communities. These changes are manifested at multiple scales ...
MULTIPLICATION AND TRANSLOCATION OF XYLELLA-FASTIDIOSA IN PETIOLES AND STEMS OF GRAPEVINE RESISTANT, TOLERANT, AND SUSCEPTIBLE TO PIERCES DISEASE
Petioles of Vitis vinifera ‘French Colombard’ (susceptible to Pierce’s disease), and V. rotundifolia ‘Carlos’ (tolerant) and ‘Noble’ (resistant) were inoculated with virulent strain FC of Xylella f...
