Cdt1_bis; Transcriptome comparison of the crl mutant and CDT1-RNAi line
Ontology highlight
ABSTRACT: au13-04_cdtbis; cdt1_bis crl mutants and CDT1-RNAi lines have very similar macroscopic phenotypes as well as identical defects in plastid division and biogenesis. Our goal wwas to determine how much of these similarities originated from similar alterations of gene expression. Plantlets of crl mutant and CDT1-RNAi lines were grown in vitro on MS1/2 medium for 14 days. CDT1-RNAi lines were compared to the corresponding wild-type (Ws), whereas crl mutants were compared to their wild-type siblings and are in the Col0 ecotype. 4 dye-swap - normal vs rnai mutant comparaison, normal vs transgenic comparaison
Project description:au13-05_sup62 - 4 mutants - Transcriptome analysis of the mutant sup62, cpsf30, two suppressors of programmed cell death in A. thaliana - Plants Col-0, mips1, sup62 and sup62 mips1 were grown for 3 weeks in Short-Day condition and subsequently transfered in Long-Day condition. Rosette leaves were sampled after 4 days in Long-Day condition. 8 dye-swap - gene knock out,genotype comparaison
Project description:cea13-01_oxi1 - oxi1 transcriptome - Transcriptomic analysis on the effect of oxi1 mutation under high light stress? - 5 weeks old mutannt (M) and wild type (WT) plants were exposed to high light and low temperature (1300-1350 µmol photons m-2s-1, 7°C/14°C day/night and 380ppm CO2) for 25 hours. ~100 mg fresh weight leaves were harvested, and total RNA prepared from them. For control experiments, leaves were harvested directly from the phytotron (No light stress). Three microarray comparisons were made: Mcontrol/WTcontrol, Mstress/WTstress and Mstress/Mcontrol . For each comparison, 2 biological replicates are performed. 6 dye-swap - genotype comparaison

Project description:au12-06_cpsf30 - cpsf30 mips1 transcriptome - How a mutation in the CPSF30 is able to suppress the cell death phenotype observed in the mips1-1 Arabidopsis mutant? - All the plants were cultivated in the same hanging conditions 10days in "short Days" then in long Days. The takings were later made 4days in "long Days" what corresponds to the appearance of the symptoms of cellular death at the mutant mips1-1. On the other hand, the gene CPSF30 codes for two transcribed. We have a double mutant mips1 cpsf30 complemented with the transcribed young. 6 dye-swap - genotype comparaison
Project description: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 80µE 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:au13-11_gravity - gravity - Cell cycle and cell proliferation are decoupled under altered gravity conditions. We have previously shown that semisolid cell cultures of Arabidopsis suffer overall genome changes in response to altered gravity and also that cell cycle stages duration is altered. By using synchronized cell cultures we will demonstrate the precise alterations in cell cycle duration and also the transcriptional signature in any of them. - Experiments consists on exposures of Arabidopsis cell cultures to 1g control/simulated microgravity (RPM) conditions. Asynchronous cells exposed for 14 h + Syncronous populations choosen to have an enrichment of cell cycle phases were used (being T7/T10 samples on G2 phase, T14/T16 samples on G1 phase). 6 dye-swap - time course,treated vs untreated comparison
Project description:Effects of deregulation of a lipid acyl hydrolase gene (PLP2, At2g26560) on global transcriptome upon infection by Botrytis cinerea. This deregulation affects resistance levels against fungal and bacterial pathogens, likely by perturbing the biosynthesis of oxylipins. Oxylipins are fatty acid-derived compounds (example:jasmonic acid) with diverse signaling or antimicrobial properties. - 2500 spores of Botrytis cinerea were pipetted on 4 infection sites per adult leaf. Leaf material was harvested at 0, 24 and 48 hours. 3 plant genotypes were used (Col-0) : PLP2- silenced (RNAi), control, PLP2-overexpressors.

Project description:rs12-08_cyp715a1 - col-0 vs cyp715a1 - The microarray analysis is part of a project aimed at characterizing the function of the cytochrome P450 CYP715A1 in Arabidopsis thaliana. - Flower buds of Arabidopsis Col-0 (wild-type) and cyp715A1 mutant were harvested for a comparative analysis of their transcriptomes. 3 dye-swap - gene knock out,genotype comparaison
