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 ...

SpotWhatR: a user-friendly microarray data analysis system

SpotWhatR is a user-friendly microarray data analysis tool that runs under a widely and freely available R statistical language (http://www.r-project.org) for Windows and Linux operational systems....

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...
