The conserved C-terminal 8 CM domains of selected plant HyPRPs. Top: multiple alignment of the conserved C-terminal domain sequences from representative HyPRPs of all major phylogenetic branches (see Figure 3). At – Arabidopsis thaliana, Le – Lycopersicon esculentum, Mt – Medicago truncatula, Os – Oryza sativa, Pt – Pinus taeda, St – Solanum tuberosum, Zm – Zea mays. Residues conserved between at least 75 % of the depicted sequences are shown on black background, positions with conserved amino acid properties on gray background. Conserved cysteines are shown in red and denoted by numbers, selected substitutions at the conserved cysteine positions are highlighted in blue. Bottom: consensus sequence expressed as a PROSITE – style pattern that detects most Arabidopsis HyPRPs and no false positives.
