Figure 3

Normalised Cluster Length per Species. Cumulative plots of miRNA cluster size (in bp/genome size) per species, normalised by total genome length. Species are coloured according to the grouping shown in Figure1 and listed in Additional file1: Table S1; (a) clusters that contain only protein coding genes; (b) Mixed clusters containing both protein coding and miRNA genes; (c) Clusters containing only miRNA loci.
