TAIR (The Arabidopsis Information Resource)
The leading resource for plant biologists
TAIR (The Arabidopsis Information Resource) is a one-stop resource for everything related to Arabidopsis thaliana, a key reference plant for researchers. Established in 1999, TAIR offers the most comprehensive and current set of plant gene function data in the world, including individual genes, genetic sequences, gene family, gene expression, and the complete genome map — all augmented with links and citations to the relevant literature alongside built-in visualization tools.
TAIR is constantly updated, curated, and maintained by PhD plant biologists who ensure that all the information we provide is current, vetted, and reliable. TAIR curators read peer peer-reviewed research articles, identify relevant experimental data, and organize it into the TAIR database, creating metadata using a controlled vocabulary that enables powerful search and cross reference across organisms. Each year, over 3,000 articles and 5,000 experiment-based annotations are added to the database, making TAIR an indispensable resource for thousands of researchers in plant biology, pharmacology, and crop science.

Testimonials
“The world’s most valued plant database”
“TAIR saved me three months of map-based cloning work due to its morphological phenotype database.”
“The huge datasets provided by TAIR really help us doing bioinformatics analysis of small RNAs in Arabidopsis.”
“TAIR is *the* resource for plant scientists like me involved in both experimental and computational work…. Rarely does a day go by when I don’t use TAIR. It is a clear model for web resource for other plants.”
“TAIR has been a critical tool in every project and stage of my scientific development; from grad student to post-doc to PI. The TAIR resource is invaluable not only in Arabidopsis systems, but as an annotation and comparative tool in plant biology. I highly recommend TAIR.”
