Anterior Foregut Microbiota of the Glassy-Winged Sharpshooter Explored Using Deep 16S rRNA Gene Sequencing from Individual Insects
The glassy-winged sharpshooter (GWSS) is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidi...
A survey of potential insect vectors of the plant pathogenic bacterium Xylella fastidiosa in three regions of Spain
The emergence of a rapid-spreading olive disease associated with Xylella fastidiosa in southern Italy represents a high risk to susceptible crops in other countries of the Mediterranean basin, if i...
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 ...
Breaking dogmas: the plant vascular pathogen Xanthomonas albilineans is able to invade non-vascular tissues despite its reduced genome
Xanthomonas albilineans, the causal agent of sugarcane leaf scald, is missing the Hrp type III secretion system that is used by many Gram-negative bacteria to colonize their host. Until now, this p...
BRIEF HISTORICAL ACCOUNT OF OLIVE LEAF SCORCH ("BRUSCA") IN THE SALENTO PENINSULA OF ITALY AND STATE-OF-THE-ART OF THE OLIVE QUICK DECLINE SYNDROME
"Brusca" (leaf scorch or marginal leaf burn) is a disease of olive (Olea europaea) typically characterized by the desiccation and death of tissues at the tip and/or along the edge of the leaf blade...
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...
Characterization and Correlation of EPG Waveforms of Bactericera cockerelli (Hemiptera: Triozidae): Variability in Waveform Appearance in Relation to Applied Signal
The tomatoDpotato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), was recently shown to be a vector of " Candidatus Liberibacter solanacearum" (Lso), a phloem-limited bacterium that ...
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...
Cooperative efforts contained spread of Pierce's disease and found genetic resistance
An outbreak of Pierce's disease of grapevine in the Temecula Valley in the late 1990s was one in a decades-long series of sporadic appearances of this infection in California. However, the new outb...
DETECTION OF XYLELLA FASTIDIOSA IN OLIVE TREES BY MOLECULAR AND SEROLOGICAL METHODS
Xylella fastidiosa has recently been identified in the Apulian province of Lecce (south-eastern Italy) in olive trees affected by a devastating disease denoted Olive Quick Decline Syndrome (OQDS), ...
Direct tissue blot immunoassay for detection of Xylella fastidiosa in olive trees
A direct tissue blot immunoassay (DTBIA) technique has been compared with ELISA and PCR for detection of Xylella fastidiosa in olive trees from Apulia (southern Italy). Fresh cross-sections of youn...
Diversity and abundance of leafhoppers in Canadian vineyards
Leafhoppers (Hemiptera: Cicadellidae) are pests of many temperate crops, including grapevines (Vitis species). Uncontrolled populations can induce direct and indirect damage to crops due to feeding...
