Summary of C. elegans miRNA relationships. Table 1. cont. MicroRNAs of Worms and Flies miRNA Group ID let-7 Sequence-Related miRNAs 59 Sequence Full Sequence cel-miR-84 miRNA Group ID Sequence-Related miRNAs 84/139 C. elegans miRNAs can be classified into 20 groups that share either identity at the 59 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. doi:10.1371/journal.pone.0002818.t001 PLoS ONE | www.plosone.org 3 July 2008 | Volume 3 | Issue 7 | e2818 59 Sequence cel-miR-360 cel-miR-63 cel-miR-64 cel-miR-65 cel-miR-66 cel-miR-228 cel-miR-229 cel-miR-790 cel-miR-791 cel-miR-75 cel-miR-79 cel-miR-58 cel-miR-80 cel-miR-81 cel-miR-82 cel-miR-1018 cel-miR-1022 cel-miR-86 cel-miR-785 cel-miR-231 cel-miR-787 cel-miR-87 cel-miR-233 cel-miR-356 cel-miR-238 cel-miR-239a cel-miR-239b cel-miR-251 cel-miR-252 cel-miR-1 cel-miR-232 cel-miR-256 cel-miR-357 cel-miR-796 cel-miR-72 cel-miR-73 cel-miR-74 cel-miR-266 cel-miR-268 cel-miR-269 Full Sequence cel-miR-64 cel-miR-65 cel-miR-65 cel-miR-78 cel-miR-272 cel-miR-82 cel-miR-82 cel-miR-239b cel-miR-252 cel-miR-256 cel-miR-266 cel-miR-268 cel-miR-270 cel-miR-269
