84/139 C. elegans miRNAs can be classified into 20 groups that share either identity at the 5′ end (81 miRNAs, listed separately in Dataset S1) and/or homology over sequence length (45 miRNAs with ≥70%, listed separately in Dataset S2). See text and Methods for explanation of match criteria. The miRNA group ID chosen is the miRNA closest to the consensus sequence of the grouped related miRNAs. Less closely related C. elegans miRNAs with 60–69.9% sequence similarity over full length are listed in Dataset S3.
