Heatmap of the frequencies of T-RFs detected in five host species. (a) The complete heatmap showed the frequencies of all the T-RFs and the clustering results of the T-RFs and host species. (b) The first branch of the clustering of the T-RFs in (a) containing most frequent T-RFs. The color change from green to red indicates the frequency changing from 0 to 1.
