Project description:Purpose: The purpose of this experiment was to identify the gene expression changes in Arabidopsis thaliana seedlings induced by 1 h of 100 µM NAE 18:3 treatment. Methods: mRNA profiles of 4-day-old Arabidopsis thaliana seedling were generated by deep sequencing, in triplicate, using Illumina HiSeq. The sequence reads that passed quality filters were analyzed at the transcript level using TopHat followed by Cufflinks. qRT–PCR validation was performed using SYBR Green assays
Project description:These data provide a basis for exploration of gene expression differences between physiologically diverse accessions of Arabidopsis thaliana. Recent studies have documented remarkable genetic variation among Arabidopsis thaliana accessions collected from diverse habitats and across its geographical range. Of particular interest are accessions with putatively locally adapted phenotypes – i.e., accessions with attributes that are likely adaptive under the climatic or habitat conditions of their sites of origin. These genotypes are especially valuable as they may provide insight into the genetic basis of adaptive evolution as well as allow the discovery of genes of ecological importance. Therefore we studied the physiology, genome content and gene expression of 18 physiologically diverse accessions. The gene expression studies were conducted under two levels of soil moisture and accompanied by physiological measurements to characterize early responses to soil moisture deficit.
Project description:We produced RNA-Seq reads from messenger RNA isolated from aerial seedling tissue for 9 hybrids (F1s) generated by crossing in a pairwise manner 18 of the founding accessions (inbred strains) of the Multiparent Advanced Generation Inter-Cross (MAGIC) genetic mapping resource for Arabidopsis thaliana (see Gan et al. 2011. Nature, 477:419-23 for a description of the MAGIC genetic mapping resource). The resulting RNA-Seq data provides a resource to assess allele-specific gene expression between A. thaliana accessions.
Project description:These data provide a basis for exploration of gene expression differences between physiologically diverse accessions of Arabidopsis thaliana. Recent studies have documented remarkable genetic variation among Arabidopsis thaliana accessions collected from diverse habitats and across its geographical range. Of particular interest are accessions with putatively locally adapted phenotypes M-bM-^@M-^S i.e., accessions with attributes that are likely adaptive under the climatic or habitat conditions of their sites of origin. These genotypes are especially valuable as they may provide insight into the genetic basis of adaptive evolution as well as allow the discovery of genes of ecological importance. Therefore we studied the physiology, genome content and gene expression of 18 physiologically diverse accessions. The gene expression studies were conducted under two levels of soil moisture and accompanied by physiological measurements to characterize early responses to soil moisture deficit. The basic experimental design involves 18 accessions crossed with two environmental levels (well-watered soil and mild soil drying) and 3 biological replicates per accession/treatment combination.
