A tool for identification of plant long non-coding RNAs.
Long non-coding RNAs (lncRNAs) correspond to an eukaryotic non-coding RNA class that has gained emerging attention in the last years as a higher layer of regulation for gene expression in cells. There is, however, a lack of specific computational approaches to reliably predict lncRNA in plants, which contrast with the variety of prediction tools available for mammalian lncRNAs. This distinction is not obvious, given that the biological features and mechanisms generating lncRNAs in the cell are likely different between animals and plants.
Here, we present RNAplonc, a classifier approach for the identification of lncRNAs in plants from mRNA-based data. This tool was created and trained with lncRNA and mRNA data from five plant species (thale cress, cucumber, soybean, western balsam-poplar and Asian rice), and it uses only 16 features robustly selected from more than 5,000 features with the REPTree algorithm.
After an extensive comparison with other largely used tool in plants, we found that RNAplonc obtained a better accuracy (92%) with the training dataset when compared to the 77% of accuracy obtained with the CPC tool. We also found that RNAplonc produced more reliable lncRNA predictions from plant transcripts, as estimated for 17 datasets of 13 different species of CANTATAdb, GreeNC and PNRD databases.
