From: Genes encoding pentatricopeptide repeat (PPR) proteins are not conserved in location in plant genomes and may be subject to diversifying selection

Figure 5

Alignment of protein coding sequences of PPR encoding restorer of fertility genes with PPR genes of the 4.3 and 23 megabase regions. Rfo from Ogura radish, Rf-1 from petunia and Rf-1 from rice are all highly related to the PPR genes from Arabidopsis thaliana chromosome one 4.3 and 23 megabase regions. They are less highly related to other PPR genes from other subgroups and locations. It is likely that PPR genes which act as restorers all originated from the same progenitor PPR gene. As this alignment shows, the repeat structure among these genes is conserved from sequence to sequence, even between different species. The asterisk (*) indicates a sequence insertion present only in Rfo.
