The Arabidopsis Information Resource (TAIR) is the primary database for the model plant Arabidopsis thaliana, providing comprehensive genomic and genetic data. TAIR's data is primarily derived from manual curation of research literature and direct submissions from the research community. Recent developments include the addition of the GBrowse genome viewer, a redesigned homepage, and several web services. The latest genome annotation release (TAIR7) includes 27,029 protein-coding genes, 3,889 pseudogenes or transposable elements, and 1,123 ncRNAs, with 681 new genes and 1,002 new splice variants added. TAIR7 also updated 10,098 loci, one-third of all loci from the previous release. TAIR's data sources include manual curation, computational pipelines, import from GenBank and ABRC, and community submissions. TAIR has enhanced its user interface with a redesigned homepage, navigation structure, and portal pages to improve usability. The addition of GBrowse allows for better visualization of genomic annotations and features from multiple sources. TAIR also provides various data files and web services for bulk data retrieval and analysis. The genome annotation process involves both manual and automated updates, with a focus on refining gene structures and functional annotations. Future releases aim to incorporate corrections to chromosome sequences, improve annotation of transposable elements and pseudogenes, and refine splice variants.The Arabidopsis Information Resource (TAIR) is the primary database for the model plant Arabidopsis thaliana, providing comprehensive genomic and genetic data.
