The Me-lncRNAs was constructed by using cassava genome version 6.1 (Phytozome version 12.0) based on integrating of comparative- and transcriptome- based approach. Six plant genomes; Arabidopsis (Arabidopsis thaliana), Poplar (Populus trichocarpa), Castor bean (Ricinus communis), Jatropha (Jatropha curcas) and 2 cassava cultivars (W14 and KU50) were retrieved from plant genome databases for ncRNAs prediction by using comparative-based algorithm, RNAz. Seventy-four cassava RNA-seq datasets generated from 5 publications and previously published ncRNAs in RNAcentral, NCBI, GreeNC, CANTATAdb, miRbase and Rfam were used for verification. Finally, novel ncRNAs with expression supporting and passed through the filtering criteria were designated as Me-lncRNAs. Expression evidence of Me-lncRNAs indicates by number of publications supporting the expression. Of these with differential expression under cold and/or drought stress were predicted their targets based on cis- or trans- regulation.
