The Arabidopsis Information Resource

The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana . Data available from TAIR includes the complete genome sequence along with gene structure, gene product information, metabolism, gene expression, DNA and seed stocks, genome maps, genetic and physical markers, publications, and information about the Arabidopsis research community. Gene product function data is updated every two weeks from the latest published research literature and community data submissions. Gene structures are updated 1-2 times per year using computational and manual methods as well as community submissions of new and updated genes. TAIR also provides extensive linkouts from our data pages to other Arabidopsis resources.

The Arabidopsis Biological Resource Center at The Ohio State University collects, reproduces, preserves and distributes seed and DNA resources of Arabidopsis thaliana and related species. Stock information and ordering for the ABRC are fully integrated into TAIR.

TAIR is located at the Carnegie Institution for Science Department of Plant Biology and funded by the National Science Foundation.

Updates on TAIR funding are available here.

Breaking News

ABRC Ordering Policy [July 27, 2010]
Effective August 1, 2010 we can no longer process orders that have both seed and DNA stocks. Please make separate orders.

TAIR Slowdowns [May 26, 2010]
Due to recent increases in usage TAIR will continue to be slow or unavailable during peak use times (weekdays 12:00-16:00 GMT) in May and June. If the site is slow please return during nonpeak hours. Please avoid pressing the reload button or resubmitting the same URL if you don't get a response; this just overloads the server with more requests for data. We will migrate to faster servers in July, this should eliminate the problems. IMPORTANT: please do not run scripts to collect data from TAIR pages, contact us instead for an ftp file.

ASPB Early Bird Registration Deadline [April 30, 2010]
The Early Bird Registration Deadline of this year's Plant Biology Meeting in Montreal is fast approaching! Register by Friday, May 7th.

New Set of Natural accessions available at ABRC [April 29, 2010]
80 natural sequenced accessions of Arabidopsis thaliana from the D. Weigel laboratory at the Max Planck Institute for Developmental Biology, as part of the 1001 Genomes Project, are now available from ABRC.

Arabidopsis N-Browse added to TAIR tools. [April 1, 2010]
N-Browse, a molecular interaction viewer, is now available at TAIR and allows users to visualize protein interactions of their Arabidopsis genes of interest. Go to the TAIR N-Browse page.

TAIR Survey [March 10, 2010]
Please take the survey to help us gather information on who uses TAIR and give feedback on future priorities. Survey will be up for only one week, please don't delay!

First ABRC Mutant Hunt [February 11, 2010]
We would like to invite you to visit ABRC and look for your favorite mutant in our greenhouses during our Spring growing cycle.

New Protein Chip Resource at ABRC [January 13, 2010]
Approximately 400 copies of Arabidopsis Protein Chip v1 ATPROTEINCHIP 1, developed by M. Snyder, S.P. Dinesh-Kumar, and M. Gerstein are now available at ABRC.
