A new regulatory DNA motif of the gamma subclass proteobacteria: identification of the LexA protein binding site of the plant pathogen Xylella fastidiiosa
Escherichia coli LexA protein is the repressor of a gene network whose members are directly involved in the repair of damaged DNA and in the survival of bacterial cells until DNA lesions have been ...
Disruption of Xylella fastidiosa CVC gumB and gumF genes affects biofilm formation without a detectable influence on exopolysaccharide production
Xylella fastidiosa causes citrus variegated chlorosis (CVC), a destructive disease of citrus. Xylella fastidiosa forms a biofilm inside plants and insect vectors. Biofilms are complex structures in...
DNA microarray-based genome comparison of a pathogenic and a nonpathogenic strain of Xylella fastidiosa delineates genes important for bacterial virulence
Xylella fastidiosa is a phytopathogenic bacterium that causes serious diseases in a wide range of economically important crops. Despite extensive comparative analyses of genome sequences of Xylella...
Gene disruption by homologous recombination in the Xylella fastidiosa citrus variegated chlorosis strain
Mutagenesis by homologous recombination was evaluated in Xylella fastidiosa by using the bga gene, coding for R-galactosidase, as a model. Integration of replicative plasmids by homologous recombin...
Stable transformation of the Xylella fastidiosa citrus variegated chlorosis strain with oriC plasmids
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. fasti...
