Phylogenetic analysis of CADs and oxidoreductases involved in specialized metabolism (ORSMs). Proteins are listed with BLASTP analyses that were performed using Arabidopsis CHR as a query. Proteins with BLAST scores higher than 250 were chosen, and those studied at least at the protein level were selected to construct the tree (Supplemental Table S2). In vivo functions of the CADs in lignin synthesis have been characterized in mutant expression studies for the genes indicated by blue stars. The scale bar represents 0.09 amino acid substitutions per site.
