Title Toward genome-wide metabolotyping and elucidation of metabolic system: metabolic profiling of large-scale bioresources
Description We established a novel methodology, termed widely targeted metabolomics, which can generate thousands of metabolome data points in a high-throughput manner. We previously conducted a targeted metabolite analysis of large-scale Arabidopsis bioresources, namely transposon-tagged mutants and accessions, to make a smaller dataset of metabolite accumulation. In this paper, we release approximately 3,000 metabolic profiles obtained by targeted analysis for 36 metabolites and discuss the possible regulation of amino acid accumulation.

Title Seeds of transposon-tagged mutants and Seeds of 225 accessions of Arabidopsis
Organism - Scientific Name Arabidopsis thaliana
Organism - ID NCBI taxonomy:3702
Compound - ID
Compound - Source
Preparation Seeds of transposon-tagged mutants were analyzed for metabolic profiling. From the Ds transposon singlecopy insertion lines that we previously established (Kuromori et al. 2006), we used 2,656 knockout mutants in which the Ds transposon was homozygously inserted into the coding regions. For each gene mutant, seeds were harvested from an F3 individual plant described in Kuromori et al. (2006). Briefly, F3 seeds were sown on agarsolidified MS medium containing 3% w/v sucrose and 20 lg mL-1 hygromycin. After stratification at 4℃ for 1 week, plants were grown for 3 weeks under a 16-h light/8-h dark cycle at 22℃, transferred to soil and grown under the same conditions with application of 2,000-fold diluted Hyponex (Hyponex Japan Co Ltd., Osaka, Japan) until seed maturity.

Sample Preparation Details Information

Title Sample Preparation
Description Seeds of 225 accessions of Arabidopsis were also analyzed for metabolic profiling. Seeds of each accession were sown on soil and germinated plants were grown in a greenhouse under natural light at 22℃ with application of 2,000-fold-diluted Hyponex until flowering finished. Then seeds were desiccated on plants for 1.5–2 months, harvested, and then stored at 4℃ and 20% humidity until use.
