Morphological evidence for phages in Xylella fastidiosa [PDF]

Virology Journal, 2008
Presumptive phage particles associated with Xylella fastidiosa strain Temecula-1 grown in PW broth were observed by transmission electron microscopy (TEM) in ultrathin sections of bacterial cell-containing low speed centrifugation pellets and in partially purified preparations from CsCl equilibrium centrifugation density gradients.

Pest categorisation of Xylella taiwanensis

EFSA Journal, 2023
The EFSA Plant Health Panel performed a pest categorisation of Xylella taiwanensis, a Gram-negative bacterium belonging to the Xanthomonadaceae. The pathogen is a well-defined taxonomic entity, and it is the causal agent of the pear leaf scorch. X. taiwanensis is present in subtropical and temperate areas of the island of Taiwan, where it affects low ...

Secondary Metabolites in Xylella fastidiosa–Plant Interaction [PDF]

Pathogens, 2020
During their evolutionary history, plants have evolved the ability to synthesize and accumulate small molecules known as secondary metabolites. These compounds are not essential in the primary cell functions but play a significant role in the plants’ adaptation to environmental changes and in overcoming stress.

Updated pest categorisation of Xylella fastidiosa [PDF]

EFSA Journal, 2018
Following a request from the European Commission, the EFSA Plant Health Panel updated its pest categorisation of Xylella fastidiosa, previously delivered as part of the pest risk assessment published in 2015. X. fastidiosa is a Gram-negative bacterium, responsible for various plant diseases, including Pierce's disease, phony peach disease, citrus ...

Contribution of rpfB to Cell-to-Cell Signal Synthesis, Virulence, and Vector Transmission of Xylella fastidiosa

Molecular Plant-Microbe Interactions, 2012
In Xylella fastidiosa the fatty acid signal molecule diffusible signaling factor (DSF) is produced and sensed by components of the regulation of pathogenicity factors (rpf) cluster; lack of DSF production in RpfF mutants results in a non-vector ...
