Project description:This is the study of the Heat Shock response of phytopathogenic bacteria Xylella fastidiosa. This series keeps the 25 minutes 40oC stimulus response (Aug 2005). Keywords: stress response; heat shock response
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.
Project description:In this study, we showed that three bacteria were able to inhibit the mycelial growth of the phytopathogenic fungus Thielaviopsis ethacetica, by the emission of microbial volatile organic compounds (mVOCs). Aiming to understand the molecular mechanisms of these interactions, we evaluated the transcriptomic response of T. ethacetica to the mVOCs produced by one of these bacterial isolates.

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.
Project description:adt09-02_fireman - fireman vs wt erwinia infection - A meta-analysis ot the CATMA transcriptomic data has shown that an orphan gene of Arabidopsis: AT5E39460, recently remaned AT5G 44585, is highly responsive to biotic stresses. An homozygous mutant of this gene, named fireman has been produced and displays less cell death symptoms in comparison to the wild type in response to Erwinia amylovora infection. The purpose of this transcriptomic analysis is to understand which pathways are altered in this mutant versus the wild-type in response to this phytopathogenic bacteria. - 3 inoculated leaves of 5 weeks old plants, per plant, have been harvested 24h after inoculation with H20 or E. amylovora, strain 1430. Keywords: normal vs disease comparison, normal vs transgenic comparaison 8 dye-swap - CATMA arrays
