Biological traits of Xylella fastidiosa strains from grapes and almonds
Xylella fastidiosa is a xylem-limited bacterium that causes various diseases, among them Pierce's disease of grapevine (PD) and almond leaf scorch (ALS). PD and ALS have long been considered to be ...
Host colonization differences between citrus and coffee isolates of Xylella fastidiosa in reciprocal inoculation
Citrus variegated chlorosis (CVC) and coffee stern atrophy (CSA) are important diseases in Brazil associated with closely-related strains of Xylella fastidiosa, but little is know about host overla...
Modulation of growth, twitching movement and biofilm formation in Xylella fastidiosa mediated by gene PD0913 under different calcium concentrations
Xylella fastidiosa (Xf) is an insect transmitted, xylem-limited bacterium that causes disease in many economic and ecologically important host plants. A key feature involved in the virulence mechan...
MULTIPLICATION AND MOVEMENT OF XYLELLA-FASTIDIOSA WITHIN GRAPEVINE AND 4 OTHER PLANTS
Xylella fastidiosa, a xylem-limited bacterium that causes Pierce's disease of grapevine and other plant diseases, has numerous symptomless hosts. The multiplication and spread of X. fastidiosa with...
Passive Pathogen Movement via Open Xylem Conduits in Grapevine Graft Unions
In grapevines, scion-rootstock grafting is a common practice to impart pathogen resistance and to manipulate aspects of grapevine physiology, including vigor, yield, and fruit composition. Successf...
Xanthomonas campestris RpfB is a fatty Acyl-CoA ligase required to counteract the thioesterase activity of the RpfF diffusible signal factor (DSF) synthase
In Xanthomonas campestris pv. campestris (Xcc), the proteins encoded by the rpf (regulator of pathogenicity factor) gene cluster produce and sense a fatty acid signal molecule called diffusible sig...
Xylella fastidiosa infection and ethylene exposure result in xylem and water movement disruption in grapevine shoots
It is conventionally thought that multiplication of the xylem-limited bacterium Xylella fastidiosa (Xf) within xylem vessels is the sole factor responsible for the blockage of water movement in gra...
Xylem structure and connectivity in grapevine (Vitis vinifera) shoots provides a passive mechanism for the spread of bacteria in grape plants
Bacterial leaf scorch occurring in a number of economically important plants is caused by the xylem-limited bacterium Xylella fastidiosa (Xf). In grapevine, Xf systemic infection causes Pierce's di...
