ABSTRACT: rs09-10_fwa - oct07. Impact of loss of DNA methylation and small interference RNAs (siRNAs) on gene expression. Mutants impaired for the DNA methylation maintenance pathway and for the RNA interference machinery were compared to mutants simultaneously impaired for both machineries to estimate their impact on genome activity. 8 dye-swaps. Gene knockout.
Project description:rs09-06_silencing-muntants - silencing mutants - Find endogenous targets of SDE3, SDE5 and IR71. - Lines IR71 KO n°3, smd8#25, sde3 (Col-0), sde5 (Col-0), Suc-SUL(Col-0) and Col-0 were grown for 11 days on MS solid medium, seedlings were then transferred in MS liquid medium and harvested 2.5 days after. Keywords: genotype comparaison 8 dye-swap - CATMA arrays
Project description:ra09-01_qtlleafgrowth - sg1-sg3 - 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 where we have mapped and cloned the concerned QTL and 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 Bur x Col RIL set, homozygous and identical everywhere in the genome except for the 23.4 kb at SG1 loci where one genotype is Bur (97.4 and 175.4) and the other is Col (97.1 and 175.1). 4 dye-swap - genotype comparison
Project description:gnp_blan06_torpten - rnai tor time course - The impact of the TOR pathway on growth and stress responses. Modification of translational and transcriptional profiles in Tor-inducible RNAi mutants and identification of TOR targets. 28 dye-swaps - normal vs. rnai mutant comparison.
Project description:rs10-05_tcv - gene profiling of turnip crinkle virus (tcv) sirna - 1. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA in A.thaliana? 2. There are also differentially regulated during an evolution and a fitness process? - This is a plant evolution project on TCV in which, the biological questions are: 1. What are the genes (including miRNA precursors) that are differentially regulated in Col0 and dcl234 mutant in wt conditions? 2. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA in Col0 and dcl234 mutant? 3. There are also differentially regulated between the plant generations 1 (G1) and 11 (G11)? 4. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA after fitness experiment? 24 dye-swap - gene knock out,treated vs untreated comparison
Project description:au09-03_gamma-irradiation - 2 doses of ionising radiations (x-rays) - Metabolic pathways involved in the response of plants to ionising radiation treatment. - Arabidopsis thaliana (Col-0) seeds were grown in Petri dishes under sterile conditions until they had 2-rosette-leaves (on average 10 days). Then they received a dose of 10 or 40 gray of X-ray (Faxitron HP). Plant were harvested 2 and 26 hours after irradiation, immediatly frozen and stored at -80°C until RNA extraction (Rneasy plant mini Kit, Qiagen) . Experiment was carried in duplicates and a non irradiated control was done for each time. 8 dye-swap - dose response,time course
Project description:adt05-04_drn - drn/drn-l expressing cells vs non-expressing cells - DRN targets - In primordia timing (pt) mutant background DRN::erGFP transgenic cell culture (somatic embryos suitable to regenerate plants) has been protoplasted and protoplasts have been sorted for GFP+ and GFP- cells. Total RNA was extracted and sent to Evry for comparison (samples DRN a,b,c). DRN-L::erGFP transgenic cell culture has been protoplasted and protoplasts have been sorted for GFP+ and GFP- cells (samples DRN-L-2-1 and DRN-L-3-1). Keywords: null 5 dye-swap - CATMA arrays
Project description:ra10-04_roots - ws vs clca2/35a2/352.7 - What are the transcriptional adaptations induced by genetically modifying vacuolar nitrate transport - Plants were grown for 12 days after germination in vertical Petri dishes onto a 2mM NO3 medium (derived from Armengaud et al 2004) in long days (16h light at 65 µE). Samples consisted of pooled roots from at least 30 to 50 plants per sample. The experiment has been repeated 4 times (exp IFX1-IFX3-CPLA2-CPLA3)and samples were harvested around 11h in the morning (ie 3h after illumation). 10 dye-swap - gene knock out, genotype comparison, normal vs transgenic comparison
Project description:What are the gene expressed during meiosis pathway in Arabidopsis thalina. Comparison of total RNAs from isolated meiocytes with those isolated from root tips, and those from leaves. Comparison of transcriptomes of normal stamen (ecotype columbia) with root tips and leaves. And, comparison of transcriptomes of normal stamens (ecotype L. erecta) with stamens from sporocyteless mutant (L. erecta). Keywords: organ comparison 11 dye-swap - CATMA arrays
Project description:ra07-03_aba4 - aba4/1 - Identification of genes deregulated in aba4 mutant or overexpressers. - Comparison of different genotypes to wild type Col-0: aba4-3 mutant, two independent 35S-ABA4 transgenic lines and two independent 35S-NCED6 transgenic lines.
