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...
Feeding and survival of citrus sharpshooters (Hemiptera : Cicadellidae) on host plants
The liquid excretion and survival of the sharpshooters Dilobopterus costalimai Young and Oncometopia facialis (Signoret), vectors of Xylella fastidiosa in citrus, were measured on various host plan...
Functional and small-angle X-ray scattering studies of a new stationary phase survival protein E (SurE) from Xylella fastidiosa - evidence of allosteric behaviour
The genome data of bacterium Xylella fastidiosa strain 9a5c has identified several orfs related to its phytopathogenic adaptation and survival. Among these genes, the surE codifies a survival prote...
Importance of Xylella fastidiosa RNA metabolism for cold survival and plant virulence
Xylella fastidiosa (Xf) is a xylem-obligate plant pathogenic bacterium that causes diseases in diverse crop plants. In grapevines the infection known as Pierce’s disease, is limited to regions with...
Influences of Temperature on Homalodisca vitripennis (Hemiptera: Cicadellidae) Survival Under Various Feeding Conditions
Survival of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), was studied under various constant temperatures and feeding conditions. When provided a host ...
Persistence in Phytopathogenic Bacteria: Do We Know Enough?
Phytopathogenic bacteria affect a wide range of crops worldwide and have a negative impact in agriculture due to their associated economic losses and environmental impacts. Together with other biot...
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...
Xylella fastidiosa: An in vivo system to study possible survival strategies within citrus xylem vessels based on global gene expression analysis
Xylella fastidiosa inhabits the plant xylem, a nutrient-poor environment, so that mechanisms to sense and respond to adverse environmental conditions are extremely important for bacterial survival ...
