New economically important diseases on crops and forest trees emerge recurrently. An understanding of where new pathogenic lines come from and how they evolve is fundamental for the deployment of accurate surveillance methods. We used kiwifruit bacterial canker as a model to assess the importance of
Levansucrases of a Pseudomonas syringae pathovar as catalysts for the synthesis of potentially prebiotic oligo- and polysaccharides.

Gut microbiota influences more physiological and developmental processes of humans and animals than earlier expected. Therefore, the possibility to shape the composition and activity of this bacterial population by prebiotics becomes especially important. Inulin, a β-2,1 linked fructan polymer, fro
The bacterial alarmone (p)ppGpp is required for virulence and controls cell size and survival of Pseudomonas syringae on plants.

The stringent response, mediated by second messenger (p)ppGpp, results in swift and massive transcriptional reprogramming under nutrient limited conditions. In this study, the role of (p)ppGpp on virulence of P. syringae pv. syringae B728a (PssB728a) was investigated. The virulence of the relA/spoT
