TranscriptomicsTranscription profiling of Arabdiopsis wild type and G'4-3 seeds grown with different nitrate concentrations to investigate effects on seed dormancy
Freshly harvested Arabidopsis seeds (ecotype Col0 obtained under 10 mM nitrate nutrition, referred to as C10 seeds) are dormant and do not germinate when sown on an agarose-based medium. However, when C10 seeds are sown on 10mM nitrate or when Col0 mother plants are grown on 50 mM nitrate (referred...

TranscriptomicsTranscription profiling of Arabidopsis wild type and PII deficient plants grown on different nitrogen sources
In E.Coli, PII protein is known to be a sensor of medium nitrogen status and to regulate some nitrogen metabolism steps (e.g.glutamin synthase and ammonium transporter regulations). Arabidopsis PII protein is the only homolog gene found in the arabidopsis genome and its role is still unclear. The go...

no omics definedTranscription profiling of Arabidopsis cells treated with hydrogen peroxide for different lengths of time to investigate the involvement of small non-coding RNAs in responses to oxidative stress
Arabidopsis cells (5 days after subculturing) were cultured at 21°C, 8 h photoperiod under agitation. H2O2 2.5 µM was added to cells 5 days after subculturing and 2 hours after the beginning of the light period. Treated and control cells were collected 15 min, 1 h, 5 h and 12 h after treatment.

TranscriptomicsTranscription profiling of Arabidopsis cyp98A3 null mutant plants
The goal is to study modification of gene expression resulting from the CYP98A3 inactivation to understand how this gene has an drastic impact on plant development, and its role in homeostasis of phenolic and amino acid metabolism.

TranscriptomicsComparison of simple mutants gcn5 and hd1 and double mutant gcn5 hd1.
rs05-09_histone-acetylase - gcn5 - Different genes show an opposed expression profile in gcn5 compared to hd1. For these genes, the double mutant might show an expression similar to the wild type. - gcn5, hd1 or double mutant gcn5hd1 were grown on MS during 10 days (1.03 boyes stage). Keywords: ge...
