Figure 4.

Amino acid sequence alignment of rbcL-encoded polypeptides. The amino acid sequence as determined for the Marchantia rbcL gene is aligned with homologous sequences from the five species indicated by their genus name. Positions deviating from the M. polymorpha sequence are shown in the single letter code. Editing positions (I–XXX) are denoted by circling of the amino acid reflecting the unedited codon. The two nonsense codons at which editing occurs in A. formosae (10) are indicated by asterisks.
