Characterization and transcriptional analysis of an ECF sigma factor from Xanthomonas campestris pv. campestris
The genomic DNA segment encoding the rpoE gene and its flanking region was cloned from Xanthomonas campestris pv. campestris strain 11 (Xc11). The transcriptional start site of rpoE was located at ...
Characterization of regulatory pathways in Xylella fastidiosa: Genes and phenotypes controlled by algU
Many virulence genes in plant bacterial pathogens are coordinately regulated by "global" regulatory genes. Conducting DNA microarray analysis of bacterial mutants of such genes, compared with the w...
Global gene expression analysis of the heat shock response in the phytopathogen Xylella fastidiosa
Xylella fastidiosa is a phytopathogenic bacterium that is responsible for diseases in many economically important crops. Although different strains have been studied, little is known about X. fasti...
Global gene expression under nitrogen starvation in Xylella fastidiosa: contribution of the sigma(54) regulon
Xylella fastidiosa, a Gram-negative fastidious bacterium, grows in the xylem of several plants causing diseases such as citrus variegated chlorosis. As the xylem sap contains low concentrations of ...
Identification and in silico analysis of the Citrus HSP70 molecular chaperone gene family
The completion of the genome sequencing of the Arabidopsis thaliana model system provided a powerful molecular tool for comparative analysis of gene families present in the genome of economically r...
The iron stimulon of Xylella fastidiosa includes genes for type IV pilus and colicin V-like bacteriocins
Xylella fastidiosa is the etiologic agent of a wide range of plant diseases, including citrus variegated chlorosis (CVC), a major threat to citrus industry. The genomes of several strains of this p...
The single "Extracytoplasmic-Function sigma factor of Xylella fastidiosa is involved in the heat shock response and presents an unusual regulatory mechanism
Genome sequence analysis of the bacterium Xylella fastidiosa revealed the presence of two genes, named rpoE and rseA, predicted to encode an extracytoplasmic function (ECF) sigma factor and an anti...
