Abstract
RIKEN BioResource Center (BRC) takes over the preservation and distribution project of the Sendai Arabidopsis Seed Stock Center (SASSC) and starts distribution of the Arabidopsis natural accession seeds under the National Bio-resource Project (NBRP) supported by Japanese government (http://sassc.epd.brc.riken.jp/sassc/create_search_panel2.php?mode=general). Natural accessions must accumulate mutations that give them advantages to survive under various environmental conditions. Thus Arabidopsis accessions are useful to study the relationship between environmental adaptations and natural variations.
In this study, we try to get phenotype data by focusing on a response to osmotic stress with mannitol. As a result, Arabidopsis natural accessions showed various responses to the mannitol treatment. Since such kind of data is useful for association mapping and/or QTL analysis, we intend to develop new database which contains these phenotype data.
