Phylogenetic relationship of MAX1 amino acid sequences from rice (Oryza sativa, subsp. japonica and indica), barley (Hordeum vulgare), wheat (Triticum aestivum), sorghum (Sorghum bicolor), maize (Zea mays), foxtail millet (Setaria italica), Brachypodium distachyon, A. thaliana, conifer Torreya nucifera, fern ally Selaginalla moellendorffii and moss Andreaea rupestris. The tree is rooted with selected CYP722C members (red) and annotated with known enzyme reactions (CL = carlactone, CLA = carlactonoic acid, 4DO = 4-deoxyorobanchol, 5DS = 5-deoxystrigol). Bootstrap percentage values shown and highlighted groups indicate distinctive clades.
