Predicted Amino Acid Sequence of HCF152 and Alignments of Its PPR Motifs.
(A) Protein sequence of HCF152 with the putative plastid transit sequence underlined. The dotted line indicates the sequence translated from the upstream ATG start codon. The amino acid that is altered in the EMS allele HCF152-2 (Pro → Leu) is boxed.
(B) Alignment of the 12 putative PPR motifs. Residues identical to the consensus motif (shown at bottom) are shaded in black, and similar residues are shaded in gray.
(C) Comparison of the PPR motif arrangement in HCF152 with that of CRP1 of maize. The PPR motifs are indicated as open boxes. aa, amino acids.
