Relationship between TE age and sRNA mapping using un-weighted and genome-weighted approaches. a Age distribution in million years (my) of TE families. b Mapping of sRNA species (left panels) or expression (right panels) from ear tissue was calculated per nucleotide of full-length elements for each family. Age is cutoff at 3my to allow sufficient visualization of the x-axis. The Spearman r coefficient is shown for each plot, calculated for all elements and not only for those <3my. P values were <0.01, except those indicated by an asterisk
