Project description:Pseudomonas syringae pv. syringae 9644 (Pss9644) is a causal agent of bacterial cherry canker causing necrotic symptoms on leaves, fruits, gummosis and canker in woody tissues of sweet cherry (Prunus avium). To understand which virulent factor genes were expressed in vitro, Pss9644 was grown in rich media (King's B Broth) and minimum media (hrp-inducing minimum media). The latter mimics the in planta environment.
Project description:In order to obtain a global view about the strategies used by phytopathogenic bacteria, in response to physiologically relevant temperature changes. We used the DNA microarray technology to compare gene expression profile in the model bacterial pathogen P. syringae pv. phaseolicola NPS3121 grown at 18 M-BM-:C and 28M-BM-:C. To carry out this study, we used this DNA microarray of P. syringae pv. phaseolicola NPS3121. Each microarray experiment was repeated six times; two technical replicates with the same RNA samples and three biological replicates using RNA isolated from a different culture.
