An Evolutionary Perspective of Pierce’s Disease of Grapevine, Citrus Variegated Chlorosis, and Mulberry Leaf Scorch Diseases [PDF]
Xylella fastidiosa causes diseases on a growing list of economically important plants. An understanding of how xylellae diseases originated and evolved is important for disease prevention and management.

Stable transformation of the Xylella fastidiosa citrus variegated chlorosis strain with oriC plasmids. [PDF]
ABSTRACT Xylella fastidiosa is a gram-negative, xylem-limited bacterium affecting economically important crops (e.g., grapevine, citrus, and coffee). The citrus variegated chlorosis (CVC) strain of X. fastidiosa is the causal agent of this severe disease of citrus in Brazil and represents the ...

Gene disruption by homologous recombination in the Xylella fastidiosa citrus variegated chlorosis strain. [PDF]
ABSTRACT Mutagenesis by homologous recombination was evaluated in Xylella fastidiosa by using the bga gene, coding for β-galactosidase, as a model. Integration of replicative plasmids by homologous recombination between the cloned truncated copy of bga and ...

Variegated chlorosis (CVC) is a citrus disease, reported initially in the northwest of São Paulo state and in the Triângulo Mineiro region of Minas Gerais state in 1987. The CVC is caused by the xylematic bacteria Xylella fastidiosa.

A Survey for Strains of Xylella fastidiosa in Citrus Affected by Citrus Variegated Chlorosis and Citrus Blight in Brazil [PDF]
Polymerase chain reaction amplification of DNA from various strains of Xylella fastidiosa with tRNA consensus primers produced three different fingerprint groups. The citrus variegated chlorosis (CVC) and mulberry leaf scorch strains were unique and readily separated from each other and all other strains tested. Internal primers were designed based on

Update of the Xylella spp. host plant database – systematic literature search up to 30 June 2023
Abstract This scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updates a database of host plant species of Xylella spp.

Summary Priming is an adaptive mechanism that fortifies plant defense by enhancing activation of induced defense responses following pathogen challenge. Microorganisms have signature microbe‐associated molecular patterns (MAMPs) that induce the primed state. The lipopolysaccharide (LPS) MAMP isolated from the xylem‐limited pathogenic bacterium, Xylella
