The PNRD (Plant Non-coding RNA Database) database is the updated version of PMRD. Non-coding RNA (ncRNA) is a functional RNA molecule that is not translated into a protein, is highly abundant and functionally important. Since the PMRD is widely used as an important tool for microRNA (miRNA) study, we consider it necessary to renew our background data and integrate as many kinds of RNA as possible to help biologists with their research in the RNA world!

   Our database mainly focuses on plant species. As well as broadening the number of miRNAs and species compared to the older version, we have made many improvements. We collected 25,739 non-coding RNA records into our database, including lncRNAs, tRNA, rRNA, tasiRNA, snRNA and snoRNA, etc. We have provided many functional search and analysis tools: ncRNA keyword search, literature-based function search, miRNA-target search and online analysis including new miRNA prediction toolkit, coding potential calculator toolkit, Blast tool and customized UCSC genome browser. We think PNRD is a comprehensive analysis platform for plant ncRNA research.

  • We have updated 2534 ncRNAs' information into our database and the entries in PNRD have reached 28214 now. The number of species is 166, including 16 new plant species. For more detailed information please click here. (2016-5-2)

  • The manuscript is accepted by NAR, cheers! (2014-10-31)

  • The entries in PNRD have reached 25,737, supporting 150 plant species. The database is composed of five major function modules: 'Search', 'Browse', 'Tools', 'Download' and 'Help'. (2014-10-8)

  • Download page and Help page are available. (2014-08-10)

  • miRNA data on PNRD are updated referring to miRBase release 21. (2014-07-15)

  • Tools section is designed to integrate several useful toolkit. (2014-07-09)

  • Browse section is built for ncRNAs browse in PNRD database. (2014-06-02)

  • Search section is built for multifunctional ncRNAs search. (2014-05-17)

  • We have collected 23,313 records of different non-coding RNAs. (2014-04-05)

  • We have constructed the prototype of PNRD. (2014-03-12)
