چکیده
Introduction Xylella fastidiosa (Xf) is a Gram negative, xylem-limited, insect-vectored bacterium and is the causal agent of Pierce's Disease (PD) of grapevine (Hopkins and Purcell 2002). PD is endemic to California but the recent introduction of a more effective vector, the Glassy-Winged SharpShooter (GWSS), Homalodisca vitripennis, to Southern California shifted the epidemiology of PD from a monocylic to a polycyclic disease. This led to a PD epidemic with severe economic consequences for the Southern California grape industry. GWSS has move to the San Joaquin valley and has impacted table grape production and it now threatens to become established in the heart of the wine grape production area including Napa and Sonoma Counties. Current PD management guidelines largely rely on vector control through the use of insecticides.

The goal of this project is to develop a technology to block the vector transmission of Xylella fastidiosa to plants. The approach focuses on the disruption of X. fastidiosa-vector interactions, so that the transmission of X. fastidiosa from one plant to another is affected. Our work has demonstrated that this approach is feasible and that we can disrupt sharpshooter transmission of X. fastidio...

The goal of this research was to identify fungal endophytes and fungal natural products antagonistic to Xylella fastidiosa (Xf) that could be implemented as preventative and curative treatment for Pierce’s Disease (PD) management. We showed in in vitro bioassays that several fungal endophytes isolated from grapevine wood possess anti-Xf properties, due to the production of natural products. One...
