Transcription profiling of tissue from different developmental stages and parts of Arabidopsis Col0 and Ler0 wild type and gcn2 mutant plants

ABSTRACT: 1- Comparison of the transcriptome of two ecotypes (Col0 and Ler0): compare the transcriptome of ColO versus Ler0 for different tissues and developmental stages (seedlings 7 days, shoot 14 days, flowers, leafs 35 days)
2- Impact of SINE RNA : Analyse the consequence of the expression of a SINE RNA in Arabidopsis thaliana
3- Impact of the gcn2 mutation : Impact of the gcn2 mutation on the Arabidopsis thaliana transcriptome. GCN2 is a kinase potentially regulated by the SINE non-coding RNA

Transcription profiling of Arabidopsis wild type, AtVdac1 knock-outs, p26 knock-outs and AtVdac1-p26 double kock-outs in response to growth in medium with salicylic acid

Project description:Functions of AtVDAC1 and its partner p26 in Arabidopsis thaliana. We previously showed that knock-out mutants impaired in AtVdac1 and p26 (AtVdac1 protein partner) are hypersensitive to salicylic acid: the root growth is more inhibited in response to 30 uM salicylic acid (SA) compared to the wild type. We want to know now which genes are up- or down-regulated in the mutants in control and SA conditions. We want to compare the RNAm contents in the wild type, vdac1 and p26 mutants and, vdac1-p26 double mutant. One-week old plantlets were transferred for 2 hours on a fresh medium containing either 0 or 30uM salicylic acid. Arabidopsis lines (WT, vdac1.1, p26.1, vdac1.1-p26.1) were grown in vertical position on ABIS medium (Lanquar et al., 2006). One week-old seedlings were transferred on a fresh ABIS medium containing either 0 or 30 uM salicylic acid. After 2 hours, the all seedlings were harvested. Three replicates were done; total RNAs from these 3 experiments were mixed together for the transcriptomic analysis.

Transcription profiling of wild type and atNRT2.7 genotype Arabidopsis leaves and roots grown in high or low nitrate conditions

Project description:Does the NRT2.7 participate to the HATS? We would like to understand the function of the AtNRT2.7 in nitrate transport under limiting and non limiting nitrate conditions. Plants were harvested after 32 days for plants under high nitrogen nutrition and 42 days for low nitrogen nutrition. Plants were grown hydroponic condition (short day, 170 uE).

Transcription profiling of Arabidopsis thioredoxin reductase knock-out mutant

Project description:Transcriptomic study of a thioredoxin reductase knock-out mutant. Biological question : Thioredoxins are small redox proteins implicated in crucial pathways of cell life. They are reduced by a conserved flavoprotein named NADPH-dependent thioredoxin reductase (NTR). In order to give an insight into the functions of the NTR/thioredoxin pathway in Arabidopsis, we have used a reverse genetic approch. Both NTR genes (NTRA and NTRB) have been inactivated in the double ntra ntrb mutant. T-DNA lines have been provided by the SALK library. Surprisingly, this mutant shows a limited phenotype suggested that some additional redox pathways are involved in compensating the inactivation of the NTR/thioredoxin pathway. In order to isolate compensatory genes that would be transcriptionally induced in the ntra ntrb mutant, we have performed this CATMA project. Seeds of the wild-type Col-0 ecotype and of the ntra ntrb homozygote double mutant were sowed in soil. Three replicates of lines were made (Col-0 1, 2 and 3 ntra ntrb 1, 2 and 3) : plants were put at different places of the greenhouse and grown at different times. Germination was synchronized by 4 days at 4C and plants were grown during 17 days, until they reached a 6 rosette leaves stage. Entire plants (30 plants per sample) were harvested, frozen in liquid nitrogen and stored at -80C until extraction.

Transcription profiling of the1, prc1, prc1_the1 and prc1_the2 gene knockout Arabidopsis dark-grown hypocotyls to identify genes involved in cell wall integrity signalling

Project description:Inhibition of cellulose synthesis by chemical inhibitors or in a mutant background leads to rapid inhibition of cell elongation. This inhibition appears to be an active process, which involves feedback signalling from the cell wall. We have isolated two loci THE1 and THE2, which are identified by mutations that partially suppress the dark-grown hypocotyl phenotype in a mutant background for cellulose synthase catalytic subunit CESA6_PROCUSTE1. THE1 encodes a receptor kinase and may play a role in this feedback signalling process. To identify genes that are regulated by THE1 and THE2, we compared the transcript profiles of 5 day-old dark-grown seedlings of the1-1_prc1-1 with prc1-1 ; the1-3_prc1-8 with prc1-8 ; prc1-8 or the1-3 with WS and the2-1_prc1-1 with prc1-1.

Can we repeat the results from the first experiment; and is there a difference between the two alleles?

Transcription profiling of Arabidopsis in standards condition and in response to nickel treatment to assess the effect nicotianamine over-accumulation on the transcriptome of A. thaliana

Project description:Effect of nicotianamine over-accumulation on the transcriptome of A. thaliana in standard condition and in response to nickel treatment After germination, plants were grown hydroponically for 6 weeks in classical nutrient solution (Marques et al, New Phytol, 2004, vol 164, pp 289-95) and then treated for 48 hours with 50 uM NiSO4 or with no nickel added for control. Biological question : Nicotianamine is a known metal chelator (of Mn, Fe, Zn, Ni, Cu) suspected to be involved in metal delivery and/or circulation in planta. This project aim at understanding the effect of the modulation of the nicotianamine content on the transcriptome of Arabidopsis thaliana in control hydroponic condition and in response to nickel treatment both at the root and at the leaf level.
