X. fastidiosa is a plant pathogenic bacterium, which is causing the ‘Olive Quick Decline<br>
Syndrome’ (OQDS), on olive trees in the southern part of Apulia region. The knowledge of<br>
mechanisms regulating olive- X. fastidiosa interactions is fundamental to develop biocontrol strategies.<br>
In Pierce’s Disease (PD) the pathogen virulence relies on a fine balance between motile cells, which<br>
move and proliferate in xylem vessels, and sticky cells forming a biofilm and responsible for vessels<br>
blockage and insect acquisition. This different behaviour is regulated by diffusible signalling factors<br>
(DSF), synthesised by a bacterial rpfF...
