Xylella fastidiosa: Host Range and Advance in Molecular Identification Techniques
In the never ending struggle against plant pathogenic bacteria, a major goal is the early identification and classification of infecting microorganisms. Xylella fastidiosa, a Gram-negative bacterium belonging to the family Xanthmonadaceae, is no exception as this pathogen showed a broad range of vectors and host plants, many of which may carry the pathogen for a long time without showing any sy...
متن کاملCharacterization of novel virulent broad-host-range phages of Xylella fastidiosa and Xanthomonas.
The xylem-limited bacterium Xylella fastidiosa is the causal agent of several plant diseases, most notably Pierce's disease of grape and citrus variegated chlorosis. We report the isolation and characterization of the first virulent phages for X. fastidiosa, siphophages Sano and Salvo and podophages Prado and Paz, with a host range that includes Xanthomonas spp. Phages propagated on homologous ...
متن کاملInteraction between Xylella Fastidiosa and Curtobacterium Flaccumfaciens
Xylella fastidiosa (Xf) is a fastidious gram-negative, xylem-limited bacterium that causes diseases in many crops of economic importance, such as grape (Pierce’s disease), almond, peach, coffee, plum and citrus. Xf can infect all known Citrus sinensis cultivars and causes Citrus variegated chlorosis (CVC). One major endophyte isolated from CVC-asymptomatic plants is the bacterium Curtobacterium...
متن کاملTHE ROLE OF LIPOPOLYSACCHARIDES IN VIRULENCE, BIOFILM FORMATION, AND HOST SPECIFICITY OF XYLELLA FASTIDIOSA Principal Investigator:
This project focuses on the lipopolysaccharide (LPS) component of the outer membrane of Xylella fastidiosa (Xf). In particular, we are investigating if the O-antigen portion of this molecule contributes to Xf surface attachment and biofilm formation. More importantly, by targeting genes involved in O-antigen biosynthesis, we will determine if LPS is an important virulence factor for Xf infectio...
متن کاملTHE ROLE OF LIPOPOLYSACCHARIDE IN VIRULENCE, BIOFILM FORMATION, AND HOST SPECIFICITY OF XYLELLA FASTIDIOSA Principal Investigator:
This project aims to further elucidate the molecular mechanisms Xylella fastidiosa (Xf) employs during the infection of its host. We are focusing on the lipopolysaccharide (LPS) component of the outer membrane of Xf. LPS contains a conserved lipid A and core portion and a variable O-antigen portion. In particular, we are examining the variable portion of the LPS molecule, the O-antigen. O-antig...
