a catalog of worldwide biological databases

Accumulating published reports have confirmed the critical biological role (e.g., cell differentiation, gene regulation, stress response) for plant long non-coding RNAs (lncRNAs). However, a literature-derived database with the aim of lncRNA curation, data deposit and further distribution remains still absent for this particular lncRNA clade. PLNlncRbase has been designed as an easy-to-use resource to provide detailed information for experimentally identified plant lncRNAs. In the current version, PLNlncRbase has manually collected data from nearly 200 published literature, covering a total of 1187 plant lncRNAs in 43 plant species. The user can retrieve plant lncRNA entries from a well-organized interface through a keyword search by using the name of plant species or a lncRNA identifier. Each entry upon a query will be returned with detailed information for a specific plant lncRNA, including the species name, a lncRNA identifier, a brief description of the potential biological role, the lncRNA sequence, the lncRNA classification, an expression pattern of the lncRNA, the tissue/developmental stage/condition for lncRNA expression, the detection method for lncRNA expression, a reference literature, and the potential target gene(s) of the lncRNA extracted from the original reference. This database will be regularly updated to greatly facilitate future investigations of plant lncRNAs pertaining to their biological significance. The PLNlncRbase database is now freely available at http://bioinformatics.ahau.edu.cn/PLNlncRbase.
