Confirmation of Xylella fastidiosa infecting grapes Vitis vinifera in Costa Rica
In 2003, symptoms of Pierce Disease (PD) were observed in two vineyards established in two different localities in San Jose province (Santa Ana and La Uruca) and in La Garita, Alajuela province. Tw...
Lipopolysaccharide O-antigen delays plant innate immune recognition of Xylella fastidiosa
Lipopolysaccharides (LPS) are among the known pathogen-associated molecular patterns (PAMPs). LPSs are potent elicitors of PAMP-triggered immunity (PTI), and bacteria have evolved intricate mechani...
O antigen acts as a shield to delay early plant immune recognition of the pathogenic bacterium, Xylella fastidiosa
PAMP-triggered immunity (PTI) is the first line of plant defense against invading organisms. Initiated through the perception of conserved pathogen-associated molecular patterns (PAMPs), such as li...
Xylella fastidiosa outer membrane vesicles modulate plant colonization by blocking attachment to surfaces
Outer membrane vesicles (OMVs) of Gram-negative bacteria have been studied intensively in recent years, primarily in their role in delivering virulence factors and antigens during pathogenesis. How...
