Alignment of AmqRunx and OscRunx amino acid sequences. Identities are marked with asterisks, whereas conservative changes are marked with dots. The Runt domains are highlighted in grey and black, for reference to the scheme depicted in Figure 1. The arrows indicate predicted intron positions with respect to the coding sequence of AmqRunx. Proline residues in the C-terminal domains are highlighted in green, whereas serines and threonines are highlighted in yellow. The C-terminal WRPY motif in OscRunx is highlighted in red.
