An engineered innate immune defense protects grapevines from Pierce disease
We postulated that a synergistic combination of two innate immune functions, pathogen surface recognition and lysis, in a protein chimera would lead to a robust class of engineered antimicrobial th...
Bacteriocins from plant pathogenic bacteria
Many bacteria produce antimicrobial substances such as nonribosomally synthesized antibiotics and ribosomally synthesized proteinaceous compounds referred to as bacteriocins. Secretion of antimicro...
Differential Susceptibility of Xylella fastidiosa Strains to Synthetic Bactericidal Peptides
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 CYC...
Effect of five antimicrobial peptides on the growth of Agrobacterium tumefaciens, Escherichia coli and Xylella fastidiosa
Five lytic peptides, cecropin A (CA), cecropin B (CB), magainin I (MI), magainin II (MII) and Shiva-1 (a synthetic analog of CB), were evaluated for their antimicrobial activity against Escherichia...
Effects of the antimicrobial peptide gomesin on the global gene expression profile, virulence and biofilm formation of Xylella fastidiosa
In the xylem vessels of susceptible hosts, such as citrus trees, Xylella fastidiosa forms biofilm-like colonies that can block water transport, which appears to correlate to disease symptoms. Besid...
Global Expression Profile of Biofilm Resistance to Antimicrobial Compounds in the Plant-Pathogenic Bacterium Xylella fastidiosa Reveals Evidence of Persister Cells
Investigations of biofilm resistance response rarely focus on plant-pathogenic bacteria. Since Xylella fastidiosa is a multihost plant-pathogenic bacterium that forms biofilm in the xylem, the beha...
Influence of Vitis xylem fluid and xylem fluid plus cecropin on growth of Xylella fastidiosa
Colony growth of Xylella fastidiosa (UCLA ID and STL PD strains) was quantified after incubation for 48 h in xylem fluid of Vitis rotundifolia Michx. cv. Noble and Vitis vinifera L. cv. Chardonnay....
In vitro activities of antibiotics and antimicrobial peptides against the plant pathogenic bacterium Xylella fastidiosa
The objective of this study was to evaluate the effectiveness of antibiotics and antimicrobial peptides against 10 strains of Xylella fastidiosa. The minimal inhibitory concentration (MIC) of 12 a...
Xylella fastidiosa subsp pauca (CoDiRO strain) infection in four olive (Olea europaea L.) cultivars: profile of phenolic compounds in leaves and progression of leaf scorch symptoms
Xylella fastidiosa subsp. pauca (Xfp), strain CoDiRO, infects a broad range of olive (Olea europaea L.) cultivars. The profile of phenolic compounds, progression of leaf scorch symptoms and populat...
