The Plant RNA database and web-site incorporates knowledge from numerous independent computer-assisted searches and databases such as PsnoRNA database(Brown, Echeverria et al. 2003), PceRBase database(Yuan, Meng et al. 2017) and CSRDB(Johnson, Bowman et al. 2007)etc. The RNA database was used to classify different plant species, and such sequences are used in the database as alignments. The database ultimately establishes a unifying nomenclature for all others RNAs i.e Small nucleolar RNAs, processing and modification of other RNAs, such as ribosomal and small nuclear spliceosomal RNAs, SnoRNAs are a large family of relatively well characterized non-coding RNAs (ncRNAs)(Leader, Clark et al. 1999).
