Misregulation of AUXIN RESPONSE FACTOR 8 underlies the developmental abnormalities caused by three distinct viral silencing suppressors in Arabidopsis.

Jay Florence F Wang Yu Y Yu Agnès A Taconnat Ludivine L Pelletier Sandra S Colot Vincent V Renou Jean-Pierre JP Voinnet Olivier O

PLoS pathogens 20110512 5

In Arabidopsis, micro (mi)RNAs and trans-acting (ta-si)RNAs synthesized directly or indirectly through the DICER-LIKE-1 (DCL1) ribonuclease have roles in patterning and hormonal responses, while DCL2,3,4-dependent small-interfering (si)RNAs are mainly involved in silencing of transposable elements and antiviral defense. Viral suppressors of RNA silencing (VSRs) produced by phytoviruses to counter plant defense may perturb plant developmental programs because of the collision of their inhibitory ...[more]

Interactions between H2O2 and glutathione in gene expression

Project description:rs08-03_glutathion - glutathion - How does glutathione content or reduction state affect H2O2-induced changes in the transcriptome? - Three single Arabidopsis mutants were used: cat2, knockout for catalase2 and so enriched in H2O2; cad2, defective in glutathione content; cytGR, knockout for cytosolic glutathione reductase. Cat2 was crossed with cad2 and cyt GR, and col0, 3 single mutants, and 2 double mutants were sampled in controlled growth conditions either in 8h or 16h photoperiod.

Project description:rs10-04_mad - comparison of transcriptomes in mad mutants - What gene sets are differentially expressed in mad mutants? - Seeds of GFP171.1 (parental line), mad1, mad2, mad3, mad6 and dcl1-12 were sterilized and germinated on Murashige/Skoog medium with 0.9% agar. Plates were stratified at 4C in the dark for 4 days. The plates were then transferred to a growth cabinet at 21C under a 16h light/8h darkness light regime, and the seedlings were harvested 18 days after transfer to the growth cabinet. 10 dye-swap - genotype comparaison

Differential expression in laccase mutants of Arabidopsis thaliana

Project description:ra10-01_laccases; laccase mutations. We demonstrated that laccases are involved in lignin polymerisation. Mutants have already been tested on microarrays and there is few differences compared to wild-type. The laccase mutation seems surgical. We possess a new double mutant, called snips, with a semi-dwarf phenotype, and we want to determine its profile. Each mutant was compared to wild type. All plants were harvested at the same developmental stage in the same growth chamber between 10h30 and 11h. 10 dye-swaps. CATMA arrays.
