Figure 4

Rate of evolution of the CRR21 (A) and OTP82 (B) genes in Brassicaceae species. dN/dS for windows composed of 9 codons separated by a step of 3 codons were plotted versus the position of the midpoint nucleotide. Below the nucleotide positions the respective positions of predicted helices are indicated by boxes. Each PPR is labeled by the P, L, or S type PPR and the number of the repeat from the N-terminus. Boxes also indicate the E + and DYW domains.
