Comparison after 4 and 52 h (Chloro-Sap)

ABSTRACT: cea12-02_chlorosap - comparison after 4 and 52h - To observe the effects of guanosine penta/tetraphosphate on gene expression - Plants of four different genotypes (43A10.6, 44B1.3, H1 P3.2 and Col-0) were grown for ten days on MS/2 plates with 1% sucrose under 80ÂµE light in long-day conditions (16 hours of light, 8 hours of dark). Plants were treated at 10:30 in the morning (Time 0; 10:30 is 3 and a half hours after the onset of the light period) by flooding with 30uM dexamethasone (in aqueous solution with 0,3 % DMSO and 0,033 % Silwet L-77) for 5 minutes . Samples were taken at 4 hrs and 52 hrs after T0. Aerial parts of the seedlings were rapidly harvested and frozen in liquid nitrogen. 9 dye-swap - normal vs transgenic comparaison,time course

Project description:ra09-01_qtlleafgrowth - ego3 - What are the transcriptional consequences of the allelic contrast at SG3, SG1 and EGO3 loci mapped for its effect on shoot growth and identified at the gene level - Plants were grown in the in vitro conditions with 60 mM mannitol, where we have mapped and cloned the concerned QTL which allows us to see the phenotype linked to the segregation of the natural alleles. We are comparing 2 genotypes descending from a RIL from the Cvi x Col (H1 is Col allele containing HIF, and A2 is Cvi allele containing HIF). 2 dye-swap - genotype comparison

septante project-Impact of genetically modified plants on bacteria from rhizosphere

Project description:rs11-02_opine - septante project - We have tools to estimate this modification for the bacterial part. On the other hand, concerning the plant part, we know plants produce opines compounds but we dont know if this expression can modify the transcriptional state of the plant. - Transgenic lines producing respectively octopine and mannopine and the WT line were grown in hydroponic tanks (containing nutritive solution) under short day conditions (8h light, 24Â°C). Whole plant aged of one month were harvested and frozen in nitrogen liquid. The plants were ground with a mortar and pestle and RNA extraction was performed with the RNeasy extraction kit (QIAGEN). The RNA concentration estimation was performed on a NANODrop spectrophotometer (Nanodrop). 6 dye-swap - normal vs transgenic comparaison

nitrogen starvation -New developments towards a genetic and diagnosis use of plant mircoarrays

Project description:gnp06-01_agriarray - nitrogen starvation - Several factors affect today a more extended use of microarrays for research and as a diagnosis tool. These factors are the experimental cost, the reproducibility of the measurements and the format of the analyses. This project aims at bringing solutions in these three domains by optimizing multiplexed analyses in order to reduce cost and enhance the number of samples treated simultaneously; by proposing new couples flurophores / slide surface in order to increase the signal precision and by developing new applications such as Comparative Genomic Hybridization (GGH) or Promoter Arrays to bring the plant microarray beyond transcriptome analyses. Altogether, these approaches will allow us to construct an optimized diagnostic tool based on 96 well microplate microarrays. This multidisciplinary project bring together biologists, chemists, physicists and mathematicians to develop innovative solutions for future application of DNA microarrays. - Dual-target hybridization microarray experiment. 2 dye-swap - time course,tissue comparison

Project description:au09-01_mpk_flagellin - wt-col0_flagellin Mitogen Activated Protein Kinase (MAPK) signaling pathways are key regulators of cell proliferation, differentiation and stress effectors. The core of the MAP kinase signal transduction cascade is composed of a three-kinase module consisting of a MAP kinase kinase kinase (MAPKKK), a MAP kinase kinase (MAPKK), and a MAP kinase (MAPK). The signaling pathway is activated upon stimulation by a phosphorylation cascade. Flagellin is a protein present in the flagellum of almost all bacteria and triggers Innate Immunity in plants, mediated by a MAPK phosphorylation signal cascade. To better understand the changes occuring in wt-Col0 flagellin treatment at the gene expression level, we would like to perform a microarray transcriptomic analysis. 1 dye-swap - treated vs untreated comparison
