Phylogenetic analysis of AGO proteins in land plants. (a), The figures show an unrooted ML tree based on the amino acid sequences of all AGO proteins in land plants. (b), The figures show an unrooted ML tree based on the PtAGOs and AtAGOs. The horizontal branch lengths are proportional to the estimated number of amino acid substitutions per residue. Bootstrap values were obtained from 1000 bootstrap replicates. The arrows indicate the P. tabuliformis genes investigated in this study. (c) The catalytic DDH amino acid core in the PIWI domain of land plant AGOs. The sizes of letters represent the residue frequency of each site
