A cell-cell signaling sensor is required for virulence and insect transmission of Xylella fastidiosa.

Proceedings of the National Academy of Sciences of the United States of America - 19 Feb 2008

Abstract excerpt

Cell-cell signaling in Xylella fastidiosa, a xylem-colonizing plant pathogenic bacterium, mediated by a fatty acid Diffusible Signaling Factor (DSF), is required to colonize insect vectors and to suppress virulence to grape. Here, we show that a hybrid two-component regulatory protein RpfC is involved in negative regulation of DSF synthesis by RpfF in X. fastidiosa. X. fastidiosa rpfC mutants hyperexpress rpfF...
