Phylogenetic trees of enzymes related to organellar genome replication. Simplified phylogenetic trees (A–D). A detailed phylogenetic tree based on plant 5′–3′ exonuclease and the 5′–3′ exonuclease domains of bacterial PolI (E). Schematic comparison of the structure of PolI and plant 5′–3′ exonuclease (F).
