Characterization of Novel Virulent Broad-Host-Range Phages of Xylella fastidiosa and Xanthomonas
The xylem-limited bacterium Xylella fastidiosa is the causal agent of several plant diseases, most notably Pierce's disease of grape and citrus variegated chlorosis. We report the isolation and cha...
Control of Pierce's Disease by Phage
Pierce's Disease (PD) of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf), is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control m...
Genomic and Biological Analysis of Phage Xfas53 and Related Prophages of Xylella fastidiosa
We report the plaque propagation and genomic analysis of Xfas53, a temperate phage of Xylella fastidiosa. Xfas53 was isolated from supernatants of X. fastidiosa strain 53 and forms plaques on the s...
Morphological evidence for phages in Xylella fastidiosa
Presumptive phage particles associated with Xylella fastidiosa strain Temecula-1 grown in PW broth were observed by transmission electron microscopy (TEM) in ultrathin sections of bacterial cell-co...
Small RNA populations for two unrelated viruses exhibit different biases in strand polarity and proximity to terminal sequences in the insect host Homalodisca vitripennis
Next generation sequence analyses were used to assess virus-derived small RNA (vsRNA) profiles for Homalodisca coagulata virus-1 (HoCV-1), family Dicistroviridae, and Homalodisca vitripennis reovir...
The filamentous phage XacF1 causes loss of virulence in Xanthomonas axonopodis pv. citri, the causative agent of citrus canker disease
In this study, filamentous phage XacF1, which can infect Xanthomonas axonopodis pv. citri (Xac) strains, was isolated and characterized. Electron microscopy showed that XacF1 is a member of the fam...
The prophage sequences of Lactobacillus plantarum strain WCFS1
The Lactobacillus plantarum commensal WCFS1 contains four prophage elements in its genome. Lp1 and Lp2 are two about 40-kb-long uninducible prophages that share closely related DNA packaging, head ...
