fireman vs wt erwinia infection-Impact of the fireman mutation in the Erwinia amylovora response of Arabidopsis

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

potyvirus effect-Transcriptionnal response to potyviruses infection in Arabidopsis

Project description:ra06-05_potyvirus-ecotypes - potyvirus effect - Common and specific genes deregulated in response to various potyviruses in different Arabidopsis genetic backgrounds. - Arabidopsis thaliana ecotype Ler was inoculated with three different Potyviruses. About 4 weeks after sowing, the 6 expanded leaves plants were inoculated with the different viruses or were mock-inoculated. Seven days after inoculation, inoculated leaves were collected, RNA was extracted and virus infection controlled. Three biological repeats have been done and two dye-swaps. Keywords: normal vs disease comparison

The AmyR regulon in Erwinia amylovora

Project description:Microarray analysis was used to identify genes that were controlled by AmyR in minimal and on immature pear fruits. Consistent with amylovoran production, an inverse correlation was observed between amyR expression and the expression level of amylovoran biosynthetic genes in liquid media. Interestingly, over-expression of AmyR suppressed the expression of type III secretion system genes including hrpA, hrpN and dspEF after pear fruit infection. Consistent with levan production and swarming motility, levasucrase and flagellar genes were both down-regulated both in the amyR mutant and over-expression strains in liquid media. Together, our results suggest that AmyR plays an important role in regulating bacterial exopolysaccharide production and virulence in E. amylovora. A total of 14 samples were analyzed in two conditions: For the in vitro condition (MBMA medium + 1% sorbitol), Erwinia amylovora wild type strain (2 replicates); E. amylovora amyR mutant strain (3 replicates); E. amylovora amyR over-expression strain (3 replicates); For the in vivo condition (on wounded immature pear fruits), Erwinia amylovora wild type strain (2 replicates); E. amylovora amyR mutant strain (2 replicates); E. amylovora amyR over-expression strain (2 replicates).
