ABSTRACT: rs12-03_complex-i - complex i - Can we identify differences between mutants affecte din different subunits of complex I - direct comparison between col-0 (wild type) and 4 mutants, each mutants having different levels of residual complex I. Three biological replicates were processed 12 dye-swap - gene knock out The levels of residual complex I for the 4 mutants are as follows: mwfe (5%), 18K (traces), ca2 (10%), and 51K (0%).
Project description: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:ra14-04_nced - abaseed - Identification of abscisic acid (ABA) signaling factors and targets in Arabidopsis developing seeds by comparing ABA deficient and wild type genotypes. Transcriptome comparison of developing seeds harvested at 14 DAP from two ABA-deficient mutants (nced2 nced5 nced9 and nced2 nced5 nced6 nced9) and wild type (Columbia-0). 6 dye-swaps - gene knockout, genomic comparison.
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:ra12-06_myb118; myb118 mutation What are the genes over expressed or down regulated in seeds in response to a myb118 mutation? Plants of the different genotypes (wild-type, myb118 mutant, myb118 antisense lines named 0E3 and T16) were grown in a green house, their flower were tagged and seeds were harvested 10 days after anthesis. Seeds were extracted from the siliques, stored at -80°C prior to RNA extraction. 6 dye-swap - normal vs transgenic comparaison
Project description:au13-06_fit - bhlh39 overexpression - Analyse the responses to bHLH39 overexpression. bHLH39 is one of the transcription factors regulating iron homeostasis responses. - Six day-old seedlings (wild type and bHLH39 overexpressor) were grown on Hoagland medium. Full seedlings were harvested for analysis. 21 dye-swap - normal vs transgenic comparaison
Project description:au13-14_myb1 - transcript modification by myb1 interactants - Transcription modification produced by transgenes - We produced 5 transgenic lines, overexpressing Eg MYB1,Eg MYB1+ EgOVATE, EgMYB1+EgHISTONE, EgHISTONE, EgOVATE and the CONTROL with the empty vectors. We have 2 lines of each construction. Plants were grown in short day conditions and we sampled the inflorescence stem. 10 dye-swap - normal vs transgenic comparaison
Project description:rs12-07_pnm1 - leaf transcriptome comparison between wt and pnm1dnls plants - Identification of nuclear genes regulated by PNM1 (At5g60960) in Arabidopsis thaliana. Mature rosettte leaf transcriptomes were compared between WT and PNM1DNLS mutants. 3 dye-swap - normal vs transgenic comparaison
Project description:au13-12_polysome - transcriptome and translatome of arabidopsis wt seeds according to dormancy - Identification of transcripts that are differentially abundant (transcriptome) and transcripts that are addressed to translation (translatome) in imbibed Arabidopsis seeds in relation with dormancy. During imbibition of seeds (16h and 24h in darkness at 25°C, dormant and non-dormant seeds), transcriptome analysis is done on total RNA and translatome analysis on polysomal RNA. - At harvest seeds are dormant. They stay dormant if they are stored at -20°C (D) and become non-dormant (ND) if they are stored 3 weeks at +20°C. Arabidopsis dormant seeds do not germinate at 25°C in darkness while non-dormant seeds do. Total RNA and polysomal RNA (polysomal fractions purified on sucrose gradients) were extracted from imbibed seeds for 16h or 24h at 25°C in darkness (3 biological replicates). Transcriptome and translatome are compared for Dormant vs Non-Dormant for 16h and 24 imbibition. In silico comparison will allow to compare transcriptome and translatome for each point and type of seeds and to compare the time points (16 vs 24h) for each type of sample. 12 dye-swap - time course
Project description:au13-01_pi-plc What are the genes that are regulated by basal PI-PLC? Arabidopsis thaliana cells in suspension (5-days old). Cultivated in environment (middle) Gamborg+2,4-D. Added inhibitors 4 hr before extraction of the RNAs. We try to determine the role of phospholipases C ( PI-PLC) in the control of the basal expression of the genes of suspension of Arabidopsis thaliana. A first experience in which we used the edelfosine as inhibitor allowed us to identify numerous genes the basal expression of which is altered by this inhibition. We want to confirm these results with another inhibitor. 4 dye-swap - treated vs untreated comparison - treatment variations
