Mechanism of RNA primer removal in plastid DNA replication
The factors involved in the removal of RNA primers during plastid DNA (ptDNA) replication have been unclear. We now identify a plastid-localized 5′–3′ exonuclease (PEN1) that mediates the removal of RNA primers in ptDNA replication and provide structural insight into its mechanism of action in this process.
