RegSite Database of Plant Regulatory Elements

Release 14, May 03, 2014

Recent sequencing of many plant genomes makes the task of identifying their regulatory elements very important, yet popular regulatory site databases such as TFD or TRANSFAC list very few plant elements. One existing database, PLACE, contains relatively few entries and limited information on each element.

Current RegSite release contains 2779 motifs and more descriptive fields than PLACE, including several fields on expression and some others.

RegSite is used by Softberry for training its NSITE-PL and TSSP programs, and also is available for licensing as a stand-alone database.

An example of RegSite entry is given below. For list of RegSite motifs, click here.
