ABSTRACT: Experiment 1
Gene profiling upon biotic stress treatment
Biological question : What are the genes (incuding microRNA precursors) that are differentially regulated upon flg22 treatment?

Experiment 2

Biological question : What are the genes (including miRNA precursors) that are differentially regulated in a set of microRNA mutants?
Experiment description : Ler, dcl1-9, hen1-1 and hasty were grown for 12-day on MS solid medium ,seedlings were then transferred in MS liquid medium and harvested 2 days after.

Experiment 3
Gene profiling in siRNA mutants
Biological question : What are the genes (including miRNA precursors) that are differentially regulated in a set of siRNA mutants?
Experiment description : Col-0, dcl2-1, dcl3-1 and rdr2-1 were grown for 12-day on MS solid medium ,seedlings were then transferred in MS liquid medium and harvested 2 days after.

Experiment 4
Gene profiling in Agrobacterium-induced tumors and auxin-induced calli.
Biological question : What are the genes (including miRNA precursors) that are differentially regulated in an Agrobacterium-induced tumors compared to auxin-induced calli?
Experiment description : Col-0 plants were infected with wt Agrobacterium tumefaciens (strain A208) by stabbing the emerging stems. 18 days later, growing tumors were harvested as were the non-infected part of the stabbed-stem.In parallel, Col-0 seeds were germinated on Callus Induction Media (CIM) and 18 days later, calli were harvested.

Experiment 5
Gene profiling in tasiRNA mutants
Biological question : What are the genes (including miRNA precursors) that are differentially regulated in a set of tasiRNA mutants?
Experiment description : Col-0, dcl4-1, rdr6-1 were grown for 12-day on MS solid medium ,seedlings were then transferred in MS liquid medium and harvested 2 days after.

Experiment 6
Gene profiling upon biotic stress treatment
Biological question : What are the genes (incuding microRNA precursors) that are differentially regulated upon flg22 treatment?
Experiment description : 14-day old seedlings (Col-0 and fls2 KO) treated with 10uM of flg22 (flagellin- derived peptide) over a one hour timecourse.

Project description:Title : Characterization of genes differentially expressed in roots of transgenic arabidopsis lines expressing the p25 protein of beet necrotic yellow vein virus. Biological question : Rhizomania ("crazy root") is a severe disease of sugar beet caused by beet necrotic yellow vein virus (BNYVV), which is transmitted by the soil-inhabiting fungus Polymyxa betae. Symptoms of virus infection are characterized by a constricted tap root and a massive proliferation of fine rootlets that often undergo necrosis. BNYVV RNA-3 encodes a 25 kDa (p25) which is an important determinant of leaf symptom phenotype. It also governs BNYVV invasion of the plant root system and induction of rootlet proliferation in sugar beet. In order to obtain a better understanding of molecular aspects of disease development in roots and to characterize specific host genes involved in response to viral infection, transgenic Arabidopsis overexpressors of p25 viral protein was obtained and better characterized. It was shown that transgenic plants that efficiently expressed p25 protein produced more lateral roots. Comparative analysis (microarray) was performed between wild type Arabidopsis roots and transgenic Arabidopsis roots expressing p25 protein, in order to identify Arabidopsis genes differentially expressed in response to p25 viral protein. Experiment description: Seeds were surface sterilized, chilled at 4C for 4 days, and then germinated and grown on square Petri plates containing sterilized Murashige and Skoog (MS) medium with 1% sucrose. Such stock plates were arranged vertically in plastic racks and placed into growth chamber. After 5 days, plants were transferred carefully onto fresh MS medium big round plates. On each plate, 60 Wild Type (WT) plantlets were transferred on the half right of the plate, and 60 transgenic plantlets (B, E or T lines) were transferred on the half left of the plate. Plates were arranged horizontally and placed into growth chamber. Experiment 1 : 5 plates containing WT0A control plants and B0A transgenic plants. Experiment 2 : 5 plates containing WT1 control plants and B transgenic plants. 5 plates containing WT2 control plants and E transgenic plants. 5 plates containing WT3 control plants and T transgenic plants. Plants were harvested after 7 days (experiment 1) or 12 days (experiment 2), and WT roots or transgenic roots were pooled and conserved at -80C.

Project description:Arabidopsis thaliana transcriptome analysis in response to plant growth promoting rhizobacteria (PGPR) Experiment 1 : Changes in gene expression profile triggered during root architecture response to Phyllobacterium. Biological question : 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 description: Seeds of wild-type Arabidopsis thaliana (ecotype Columbia) were surface-sterilized and sown on agar mineral medium (see below). 4 days after storage in the dark at 4C, seedling were cultivated 6 days in a growth chamber (16 h daily, 20-22C) and then transferred on a fresh agar mineral medium inoculated or not with Phyllobacterium STM196 (2.108 cfu/ml). 6 days later, root and leaves were collected, froze on liquid nitrogen and stored at -80C. Experiment 2 : Changes in gene expression profile triggered during induced systemic resistance (ISR) Biological question : Which genes are up- or down-regulated during the ISR triggered by a rhizobacteria, in comparison with those affected by a pathogenic interaction. Experiment description: Seeds were sown on 0.8% (W/V) agar mineral medium (see below). 4 days after storage in the dark at 4C, seedling were cultivated 6 days in a growth chamber (16 h daily, 20-22C) 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. Experiment 3 : Comparison of the effects of 3 rhizobacteria on Arabidopsis thaliana transcriptome Biological question : 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. Experiment description: Seeds of wild-type Arabidopsis thaliana (ecotype Columbia) were surface-sterilized and sown on agar mineral medium. Four days after storage in the dark at 4C, seedlings were cultivated 6 days in a growth chamber (16 h daily, 20-22C) and then transferred on soil inoculated or not with 108 cfu.g-1 of Mesorhizobium loti, or 108 cfu.g-1 of Phyllobacterium STM196, or 107 cfu.g-1 of Bradyrhizobium ORS278.
