Cladograms demonstrate orthology of PPR sequences. ( A) A NJ tree built from translated CRR4, CRR21, CLB19, and OTP82 genes sequenced from Brassicaceae species along with orthologs identified in a non-Brassicaceae member Carica papaya from Phytozome v7.0. ( B) A NJ tree built from CRR21 and OTP82 nucleotide sequences from dicots available in nucleotide databases and sequenced in this study. The NJ tree distance using the Maximum Composite Likelihood nucleotide substitution model is indicated by the scale. ( A, B) Accessions for species that lack the cognate editing site are indicated by an *. Amino acids used to construct trees align to the following positions of the current gene models in Arabidopsis: CRR4 (33–446); CRR21 (38–620); CLB19 (67–467); and OTP82 (72–525).
