Analysis of the genome-wide variations among multiple strains of the plant pathogenic bacterium Xylella fastidiosa
The Gram-negative, xylem-limited phytopathogenic bacterium Xylella fastidiosa is responsible for causing economically important diseases in grapevine, citrus and many other plant species. Despite i...
Calcium-Enhanced Twitching Motility in Xylella fastidiosa Is Linked to a Single PilY1 Homolog
The plant-pathogenic bacterium Xylella fastidiosa is restricted to the xylem vessel environment, where mineral nutrients are transported through the plant host; therefore, changes in the concentrat...
Complete sequence and evolutionary genomic analysis of the Pseudomonas aeruginosa transposable bacteriophage D3112
Bacteriophage D3112 represents one of two distinct groups of transposable phage found in the clinically relevant, opportunistic pathogen Pseudomonas aeruginosa. To further our understanding of tran...
Multilocus sequence type system for the plant pathogen Xylella fastidiosa and relative contributions of recombination and point mutation to clonal diversity
Multilocus sequence typing (MLST) identifies and groups bacterial strains based on DNA sequence data from (typically) seven housekeeping genes. MLST has also been employed to estimate the relative ...
Natural Competence of Xylella fastidiosa Occurs at a High Frequency Inside Microfluidic Chambers Mimicking the Bacterium's Natural Habitats
Xylella fastidiosa is a xylem-limited bacterium that is the causal agent of emerging diseases in a number of economically important crops. Genetic diversity studies have demonstrated homologous rec...
Presence of calcium-binding motifs in PilY1 homologs correlates with Ca-mediated twitching motility and evolutionary history across diverse bacteria
Twitching motility, involving type IV pili, is essential for host colonization and virulence of many pathogenic bacteria. Studies of PilY1, a tip-associated type IV pili protein, indicate that PilY...
The iron stimulon of Xylella fastidiosa includes genes for type IV pilus and colicin V-like bacteriocins
Xylella fastidiosa is the etiologic agent of a wide range of plant diseases, including citrus variegated chlorosis (CVC), a major threat to citrus industry. The genomes of several strains of this p...
Type I and type IV pili of Xylella fastidiosa affect twitching motility, biofilm formation and cell-cell aggregation
Xylella fastidiosa, an important phytopathogenic bacterium, causes serious plant diseases including Pierce's disease of grapevine. It is reported here that type I and type IV pili of X fastidiosa p...
Xylella fastidiosa Differentially Accumulates Mineral Elements in Biofilm and Planktonic Cells
Xylella fastidiosa is a bacterial plant pathogen that infects numerous plant hosts. Disease develops when the bacterium colonizes the xylem vessels and forms a biofilm. Inductively coupled plasma o...
Xylella fastidiosa outer membrane vesicles modulate plant colonization by blocking attachment to surfaces
Outer membrane vesicles (OMVs) of Gram-negative bacteria have been studied intensively in recent years, primarily in their role in delivering virulence factors and antigens during pathogenesis. How...
