Welcome to The Arabidopsis Gene Regulatory Information Server (AGRIS)

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 three databases.

AtcisDB consists of approximately 33,000 upstream regions of annotated Arabidopsis genes (TAIR9 release) with a description of experimentally validated and predicted cis-regulatory elements.

AtTFDB contains information on approximately 1,770 transcription factors (TFs). These TFs are grouped into 50 families, based on the presence of conserved domains.

AtRegNet contains 17,694 direct interactions between TFs and target genes.

Word frequency calculations in non-coding segments of Arabidopsis genome are available here.
NEWS (Updated May 19, 2015)
  • AtRegNet has been updated (May 19, 2015) with new direct interactions between TFs and target genes.
  • Due to a recent server upgrade, we have been experiencing technical difficulty with AGRIS. If anything is not functioning, please email the AGRIS development team at We are sorry for the inconvenience.
  • AGRIS has been published in NAR 2011 Database special issue. Download PDF, read abstract or full text.
  • Transcription factors are linked to clones available at ABRC (Arabidopsis Biological Resource Center) (View sample, stock numbers are linked to corresponding stock ordering pages).
  • All the gene models correspond to TAIR9 release of Arabidopsis genome.
  • We want to hear from you. Feedback buttons are available at each page for you to provide feedback or suggestions.
