A recently emerging bleeding canker disease, caused by Pseudomonas syringae pathovar aesculi (Pae), is threatening European horse chestnut in northwest Europe. Very little is known about the origin and biology of this new disease. We used the nucleotide sequences of seven commonly used marker genes to investigate the phylogeny of three strains isolated recently from bleeding stem cankers on European horse chestnut in Britain (E-Pae). On the basis of these sequences alone, the E-Pae strains were ...[more]
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 ºC and 28ºC. 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.
