Complete Circularized Genome Resources of Seven Strains of Xylella fastidiosa subsp. fastidiosa Using Hybrid Assembly Reveals Unknown Plasmids
Xylella fastidiosa is a vascular plant pathogenic bacterium native to the Americas that is causing significant epidemics and economic losses in olive and almonds in Europe, where it is a quarantine pathogen. Since its first detection in 2013 in Italy, mandatory...
On 4 April Xylella-files seminar on priming response to Xf in grapevines
On 4 April 2023, in the context of the “Xylella Files” spring seminars, professor of plant pathology at UC Riverside Caroline Roper will discuss her research on Defense Priming and Grapevine Immune Responses to Xylella fastidiosa. "Priming" is a mechanism triggering...
Parallel host shifts in a bacterial plant pathogen suggest independent genetic solutions
While there are documented host shifts in many bacterial plant pathogens, the genetic foundation of host shifts is largely unknown. Xylella fastidiosa is a bacterial pathogen found in over 600 host plant species. Two parallel host shifts occurred—in Brazil and...
