Possible origin of the conserved and non-conserved PAPs. (A) The numbers of the PPRs which showed the indicated patterns of possible evolutional origin are shown. (B) Repetitive elements identified in each category of the PPRs. (C) The frequency of the human PPRs for which corresponding PPRs or syntenic genomic regions could be identified in the genomes of the indicated species is shown.
