Nitrate assimilation contributes to Ralstonia solanacearum root attachment, stem colonization, and virulence.

Abstract excerpt

Ralstonia solanacearum, an economically important plant pathogen, must attach, grow, and produce virulence factors to colonize plant xylem vessels and cause disease. Little is known about the bacterial metabolism that drives these processes. Nitrate is present in both tomato xylem fluid and agricultural soils, and the bacterium's gene expression profile suggests that it assimilates nitrate during pathogenesis. A...
