Xylella fastidiosa is one of the most important threats to plant health worldwide. This bacterial pathogen has a long history, causing disease in the Americas on a range of agricultural crops and t...

Certain pathogens evolve with their hosts in a stepwise arms race of virulence and resistance, mediated by one or a few genetic loci in their genomes. Other pathogens may retain the ability to colo...

Plum leaf scald (PLS) is a serious disease caused by Xylella fastidiosa, which is transmitted by sharpshooters (Hemiptera: Cicadellidae: Cicadellinae). Disease management is based on planting healt...

Generalist pathogens frequently exist as a complex of genetically differentiated strains, which can differ in virulence and transmissibility. A description of the extent to which strain variability...

Vectors play a major role in epidemiology of diseases caused by Xylella fastidiosa. Information on vector ecology, behavior and transmission sets the basis for identifying key species involved in p...
