Welcome to The Arabidopsis Gene Regulatory Information Server (AGRIS)

Please read important message below regarding updates in our website

The Arabidopsis Gene Regulatory Information Server (AGRIS) is a new information resource of Arabidopsis promoter sequences, transcription factors and their target genes. AGRIS currently contains two databases, AtcisDB (Arabidopsis thaliana cis-regulatory database) and AtTFDB (Arabidopsis thaliana transcription factor database). The two databases, used in tandem, provide a powerful tool for use in continuous research.

AtcisDB consists of 25,516 promoter sequences of annotated Arabidopsis genes with a description of putative cis-regulatory elements.

AtTFDB contains information on approximately 1,770 transcription factors. These transcription factors are grouped into 50 families, based on the presence of conserved DNA-binding domains.

AtRegNet contains 2,582 direct interactions between transcription factors and promoters.

NEWS (Last Update 06-26-2009) • In order to improve the capabilities and stability of AGRIS, we moved our website to an another server. Most functions of AGRIS were preserved and following changes took place:    • Visualization of regulatory elements by genome browser instead of GDVTK tool    • Improved ReIN tool for visualizing regulatory networks    • We are in the process of replacing our TIGR4 gene models with TAIR9 gene models • As part of collaboration with lab of Dr. Lonnie Welch, we calculated word frequencies across the Arabidopsis genome. Results for word lengths 6 through 16 are available for download (accessible after login or registration in Downloads section).
