The phylogenetic tree for the set I of 5S rRNAs. a the phylogenetic tree constructed by RNA-TVcurve, b the phylogenetic tree constructed by RNAdistance, c the phylogenetic tree constructed by RNApdist. In this figure RNAs in same the box mean they are consistent to the same known subgroup. The line is to mark the branch of the constructed tree
