NONCODE (current version v6.0) is an integrated knowledge database dedicated to non-coding RNAs (excluding tRNAs and rRNAs). Now, there are 39 species in NONCODE including 16 animals and 23 plants. The source of NONCODE includes literature and other public databases. We searched PubMed using key words ‘ncrna’, ‘noncoding’, ‘non-coding’,‘no code’, ‘non-code’, ‘lncrna’ or ‘lincrna. We retrieved the new identified lncRNAs and their annotation from the Supplementary Material or web site of these articles. Together with the newest data from Ensembl, RefSeq, lncRNAdb and GENCODE were processed through a standard pipeline for each species. The pipeline includes seven steps:
