Important Note

PLACE is migrating to NewPLACE. After the replace of machine, scheduled at 2015, this page will be switched to the new page. If you encounter a problem using the NewPLACE, please inform to the Support. Thank you.

Update of the data in the PLACE database was terminated in February 2007.

What is PLACE?

PLACE is a database of motifs found in plant cis-acting regulatory DNA elements, all from previously published reports. It covers vascular plants only (But since April 2006, we changed the policy. See the release note for PLACE 26.0). In addition to the motifs originally reported, their variations in other genes or in other plant species reported later are also compiled. The PLACE database also contains a brief description of each motif and relevant literature with PubMed ID numbers. DDBJ/EMBL/GenBank nucleotide sequence databases accession numbers will be also included. See 'sample record'. List of entries can be found in 'place.dat'.

How to use

The query sequence can be searched for the presence of motifs identical with or similar to the previously reported cis-element motifs in the PLACE database by Signal Scan Search (Sample of Signal Scan can be found in 'input.txt' and 'output.txt') .

You can submit batches of sequences to " Signal Scan Search, file upload" in FASTA format.

For the time being, PLACE is free on the following conditions.
  1. Please acknowledge the following facts in your application software (or WEB page or any pertinent publications) using PLACE that:
    1. PLACE has been constructed and maintained at NIAS (National Institute of Agrobiological Sciences).
    2. PLACE was made available by the courtesy of NIAS without charge.
  2. Please cite our publication (Higo et al. Nucleic Acids Research 27:297-300 (1999)).

Academic use: Please note that PLACE is free for academic user.

Privacy Policies:

We collects user's information through standard Web logs for the purpose of site management. We store top and second level domain name for foreign domain, adding third domain name for Japanese domain.

We are not collecting keywords, sequences submitted for PLACE database query. Some results are kept one week for future browsing by the submitter. In this case, results are guarded from others view by generating random ID. For other results, all are purged when the process are done. We will not disclose keywords, sequences and results for others.
