Table 2. Comparison of miRNA Families in B. malayi and C. elegans.

nematode	total miRNAs	total hairpins	afamilies of paralogues	bsingleton families	ctotal families	dshared families	eunique families
B.malayi	145	129	20	79	99	48	51
C.elegans	195	175	40	61	101	48	53

^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.
