Comparison of miRNA Families in B. malayi and C. elegans.

aMicroRNAs sharing a minimum of 6 contiguous nt between positions 1–7 at the 5′ end or that exhibit ≥70% identity overall in the absence of a conserved 5′ end were grouped into families of paralogues. In B. malayi, 66 miRNAs were grouped into 20 families (Table S5). In C. elegans, 134 miRNAs were grouped into 40 families (Table S6).bThe remaining miRNAs in each nematode that do not fall within a paralogous group are considered individual families consisting of a single member.cTotal number of families = number of paralogous families + number of singleton families.d48 miRNA families are shared between B. malayi (75 miRNAs) and C. elegans (113 miRNAs). See Table S7 for details.eNumber of families in a nematode with a seed sequence that is not found in the other nematode.
