Figure 1

Editing frequency {(A [number of edited codons]/B [number of codons in the genome]) × 1000} versus Grantham index[47]for all edited codons in protein coding genes in chloroplasts of A. formosae (a, forward editing; b, reverse editing), and A. capillus-veneris (c, forward and reverse editing). Amino acid residues are shown as pre-edited to edited below all codons. The vertical axis indicates Grantham index value and editing frequency. Edited codons are grouped into nonsynonymous 1st, 2nd, and silent site changes. Asterisks indicate arbitrarily assigned values of 200 for Grantham index values in premature stop codons. The dotted line denotes an upper limit of editing frequency across silent editing sites. The values obtained for A/B were multiplied by 1000 to make these data plottable against Grantham's values.
