The combined phylogenetic tree. In this tree, the PdRNAi (PdDCLs, PdAGOs, and PdRDRs) and the model plant AtRNAi (AtDCLs, AtAGOs, AtRDRs) proteins have been represented by blue and red, respectively. Here DCLs, AGOs, and RDRs families have been represented by orange, purple, and green circles, respectively
