Project description:We used three different strains of Pseudomonas syringae pv tomato DC3000 to investigate systemic responses to infection in Arabidopsis and the development of SAR. Wildtype DC3000, the hrpA mutant and DC3000 carrying the avirulence gene avrRpm1 were syringe infiltrated into 4-week-old plants at a concentration of 10e8 cfu/ml. At least 5 leaves per plant were infiltrated and at least 10 plants were pooled for each sample. Systemic, uninfected tissue was then harvested at 8, 12 and 21h after inoculation. Three independent experiments were carried out to give three biological replicates for each timepoint. 27 samples were used in this experiment.

Project description:Plants have developed a complicated resistance system, and they exhibit various defense patterns in response to different attackers. However, the determine factors of plant defense patterns are still not clear. Here, we hypothesized that damage patterns of plant attackers play an important role in determining the plant defense patterns. To test this hypothesis, we selected leafminer, which has a special feeding pattern more similar to pathogen damage than chewing insects, as our model insect, and Arabidopsis thaliana as the response plants. The local and systemic responses of Arabidopsis thaliana to leafminer feeding were investigated using the Affymetrix ATH1 genome array. Damaged leaves of Arabidopsis thaliana for local damage analysis and the intact leaves on the same plant for systemic damage analysis were separately frozen by liquid nitrogen. Then, we used an Affymetrix ATH1 Arabidopsis microarray to study the expression changes pattern of Arabidopsis thaliana to pea leafminers damage, both locally (LI) and systemically (SI). We downloaded data from the web database and used hierarchical clustering to explore the relationships of Arabidopsis thaliana expression pattern to different kinds of attackers.

Project description:ra04-07_pgpr - profiling of the pgpr induced systemic resistance (isr) - Experiment 1 : Which genes are up- or down-regulated in Arabidopsis thaliana cultivated in vitro with increased lateral root development in response to Phyllobacterium STM196 inoculation. Experiment 2 : Which genes are up- or down-regulated during the ISR triggered by a rhizobacteria, in comparison with those affected by a pathogenic interaction. Experiment 3 : which genes are specifically induced or repressed in Arabidopsis thaliana by inoculation of the soil with a PGPR vs a bacteria that has the ability to trigger nodule formation in a Legume. - Seeds were sawn on 0.8% (W/V) agar mineral medium (see below). 4 days after storage in the dark at 4degreeC, seedling were cultivated 6 days in a growth chamber (16 h daily, 20-22degreeC) and then transferred on soil inoculated or not with 107 cfu.g-1 of Bradyrhizobium strain ORS278. Three weeks later, 3 leaves per plant were infiltrated with a suspension of Pseudomonas syringae pv. tomato (2.105 cfu.ml-1) or with MgSO4 10 mM alone for control plants. Infiltrated leaves were collected 24h later. Keywords: normal vs rnai mutant comparaison,treated vs untreated comparison

Project description:During their co-evolution, plants have learned to counteract bacterial infection by preparing yet uninfected tissues for an enhanced defence response, the so-called systemic acquired resistance or priming response. Primed leaves express a wide range of genes that enhance the defence response once an infection takes place. While hormone-driven defence signalling and generation of defensive metabolites has been well studied, less focus has been set on the reorganization of primary metabolism in systemic leaves. Since primary metabolism plays an essential role for fuelling and optimizing defences in terms of providing energy and chemical building blocks, we investigated medium-term primed changes in primary metabolism at RNA and metabolite levels in systemic leaves of Arabidopsis thaliana plants that were locally infected with Pseudomonas syringae. While known defence genes were still activated 3-4 days after infection, we also found several parts of primary metabolism to be significantly altered. Nitrogen (N)-metabolism and content of amino acids and other N-containing metabolites were significantly reduced, whereas the organic acids fumarate and malate were strongly increased. We suggest that reduction of N-metabolites in systemic, yet non-infected leaves primes defence against bacterial infection by reducing the nutritional value of systemic tissue. The increased organic acids serve as a quickly available metabolic resource of energy and carbon-building blocks for the production of defence metabolites during subsequent secondary infections.

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.
