Multiple alignment of predicted Pinophyta CLE dodecapeptide amino acid sequences. Sequences are arranged by the phenotypic classifications assigned to Arabidopsis CLE proteins in , with conifer sequences grouped with their closest Arabidopsis homologue, as depicted in Figure 4A. Closest matching Arabidopsis-Pinophyta homologues are indicated by boxes and light grey highlighting over the protein names. The perfectly matching predicted CLE peptides between Arabidopsis and the Pinophyta are indicated by dark grey highlighting over the Pinophyta sequences. Mismatches in the Pinophyta sequences from their closest Arabidopsis homologue are indicated by black highlighting and inverse lettering. Perfectly matching CLE peptide sequences amongst the Pinophyta species are indicated by highlighting of various colours.
