The Arabidopsis Information Resource (TAIR) collects information and maintains a database of genetic and molecular biology data for Arabidopsis thaliana. TAIR collaborates with the Arabidopsis Biological Resource Center (ABRC) to provide researchers with the ability to search and order stocks. The ABRC's mission is to acquire, preserve and distribute seed and DNA resources that are useful to the Arabidopsis research community. The data in TAIR can be searched, viewed using GBrowse or interactive SeqViewer genome browsers, and analyzed with the databases' tools. In addition, pages on news, information on the Arabidopsis Genome Initiative (AGI), Arabidopsis lab protocols, and useful links are provided.
