Cytochromes P450 monooxygenases from the CYP98 family catalyze the meta-hydroxylation step in the phenylpropanoid biosynthetic pathway. The ref8 Arabidopsis (Arabidopsis thaliana) mutant, with a point mutation in the CYP98A3 gene, was previously described to show developmental defects, changes in lignin composition, and lack of soluble sinapoyl esters. We isolated a T-DNA insertion mutant in CYP98A3 and show that this mutation leads to a more drastic inhibition of plant development and inhibitio ...[more]

Transcription profiling of Arabidopsis CYP98A3 knockout mutant

Project description:TDNA insertion mutants in CYP98A3 were produced by K. Feldmann, and studied through transcriptomic analysis against the wild type WS (specific insertion was checked by PCR and segregation analysis). Characterization of knockout mutants for P450s can be very helpful to fully understand the function of the disrupted gene, and is expected to generate information about the molecular basis of mutants phenotype.

Transcription profiling of Arabidopsis cells to iron stress

Project description:After 7 days under normal culture conditions, an iron stress was imposed by addition of iron citrate (500 uM final concentration). This time constituted the time zero (T0) of the time-course experiment. Cells were collected from separate Erlenmeyer flasks at times T0, T+5 min, T+15 min, T+30 min, T+60 min, T+6 h, and T+24h. After filtration, cells were washed with water twice, frozen in liquid nitrogen and stored at 80C before processing for RNA extraction.

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 cold and phosphlipase treated Arabidopsis tto analyse the effect of Phospholipases C and D

Project description:The study aims at determining the genes that are induced or repressed by cold in the suspension cells. It also aims at monitoring the effect of inhibitors of PLC (U73122 vs. U73343) and PLD (ethanol vs. tertiary butanol) on cold response at the transcription level. To answer this question we chose a pharmacological approach. We decided to use molecules that are going to inhibit PLC or PLD. For PLC we use U73122 and its inactive analog as a control; for PLD we used a primary alcohol (ethanol) and a tertiary alcohol (tert-butanol) as a control. We therefore extracted RNA after the following treatments: 4 °C 22 °C 4 °C + 0.9% primary-ethanol 4 °C + 0.9% tertiary-butanol 4 °C + 60 micromolaire U73122 4 °C + 60 micromolaire U73343 The exposure at 4 °C was 4 hours.
