Foundation Plant Services is pleased to announce the release of five new Pierce’s disease (PD) resistant grapevine cultivars developed in Dr. Andy Walker’s grape breeding program. Walker used classic breeding techniques to confer PD resistance from the North American wild grape species Vitis arizonica to the cultivated winegrape V. vinifera. The five newly released cultivars […]

Authors: Brian Michael Ingel; Advisor: Caroline Roper. Published: December, 2019 Abstract: Xylella fastidiosa is a xylem-limited bacterium that causes Pierce’s Disease (PD) in grapevine. PD symptom progression is correlated with systemic colonization by X. fastidiosa, which occurs via pit membrane degradation. Previous studies determined that a polygalacturonase, one of several cell wall degrading enzymes (CWDEs) […]

Authors: Aina Baró; Isabel Mora; Laura Montesinos; Emilio Montesinos. Published: January 27, 2020 Abstract: The kinetics of cell inactivation and the susceptibility of Xylella fastidiosa subspecies fastidiosa, multiplex and pauca, to synthetic antimicrobial peptides from two libraries (CECMEL11 and CYCLO10), were studied. The bactericidal effect was dependent on the relative concentrations of peptide and bacterial […]
