Project description:These data provide a basis for the detection of sequence based polymorphisms between the Col-1, Tsu-1, and Kas-1 accessions of Arabidopsis thaliana. The experimental data provides an initial characterization of differences among the accessions, as well as a means for improving gene expression studies with the filtering of SFP from arrays studies. 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 two physiologically extreme accessions (Tsu-1 from a wet environment in Tsushima, Japan and Kas-1 from a dry environment in Kashmir, India). 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. Genomic hybridization experiments identified 42,503 single feature polymorphisms (SFP) between accessions, providing an initial screen for putative SNPs, indels, or changes in gene content.

Each accession has 6 replicates, single channel on the ATH1 array. Samples were processed in two balanced batches (bioprime random labeling, hybridization,scanning). A total of 18 arrays

Project description:We produced RNA-Seq reads from messenger RNA isolated from seedling, root, and floral bud tissue for 17 MAGIC founder accessions (inbred strains) of 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 provide a resource to assess tissue-specific expression across different accessions of A. thaliana. Note that comparable read data for accessions Col-0 and Can-0, which are also founders of the MAGIC lines, has previously been released under GEO series GSE30795 (Gan et al. 2011. Nature, 477:419-23). Examination of RNA expression across tissues (seedling, root, floral bud) for 17 Arabidopsis thaliana accessions (Bur-0, Ct-1, Edi-0, Hi-0, Kn-0, Ler-0, Mt-0, No-0, Oy-0, Po-0, Rsch-4, Sf-2, Tsu-0, Wil-2, Ws-0, Wu-0, Zu-0).

Project description:We produced RNA-Seq reads from messenger RNA isolated from root tissue for the 19 MAGIC founder accessions (inbred strains) of Arabidopsis thaliana (see Gan et al. 2011. Nature 477:419-23 for a description of the MAGIC genetic mapping resource). The read data was generated with biological replication (two replicates). The resulting RNA-Seq data provide a resource to assess root gene expression across different accessions of A. thaliana. Comparable RNA-Seq read data for the MAGIC founder accessions for aerial seedling tissue has previously been released under GEO series GSE30720 (Gan et al. 2011. Nature, 477:419-23). Examination of RNA expression in root for the 19 Arabidopsis thaliana accessions used as parents for the MAGIC lines (parental accessions are Bur-0, Can-0, Col-0, Ct-1, Edi-0, Hi-0, Kn-0, Ler-0, Mt-0, No-0, Oy-0, Po-0, Rsch-4, Sf-2, Tsu-0, Wil-2, Ws-0, Wu-0, Zu-0).

Project description:Fe deficiency stimulates a coordinated response involving reduction, transport and redistribution of Fe in the roots. The expression of genes regulated by Fe deficiency in the two contrasting Arabidopsis thaliana ecotypes, Tsu-1 and Kas-1, shows that different ecotypes can respond in diverse ways, with different Fe regulated overrepresented categories. We use microarrays to analyze the Fe deficiency responses of contrasting Arabidopsis thaliana ecotypes (Tsu-1 and Kas-1).
