Cms4:19 and at chr3-Comparing nuclear gene expression in two CMS-systems using microarray technology

ABSTRACT: ra05-11_cmsrapeseed - cms4:19 and at chr3 - -To understand how/if fertility and the mitochondrial background are interlinked. -To understand how the mitochondrial background influences the nuclear gene expression. -Compare and describe the total nuclear gene expression of CMS vs. fertile and CMS vs. Restored. -Describe and analyse genes that differ in expression (of special interest are genes that differs in both comparisons). -Group genes e.g. floral genes, highly expressed genes, transcription factors, nuclear encoded genes targeted for the mitochondrion. -Comparing two CMS-systems to elucidate differences and similarities between them. - Flower buds from four different B. napus lines (fertile cv Hanna, CMS-line 4:19, restored line 46, cv Hanna with the additon of A. thaliana chr 3) at two developmental stages (stages 0-5 and stage 8). Keywords: wt vs mutant comparison 16 dye-swap - CATMA arrays

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. Keywords: gene knock out 20 dye-swap pairs - CATMA arrays: 40 arrays

comparison of transcriptomes in mad mutants-Transcriptome analysis of miRNA action deficient mutants

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.
