Fig. 2 in A pair of threonines mark ent-kaurene synthases for phytohormone biosynthesis

Fig. 2. Representative phylogenetic tree for plant KS(L)/TPS-e subfamily. Green lines indicate KS activity, red lines KSL that mediate alternative product outcome. Green text indicates KS with known or assumed role in phytohormone biosynthesis, while blue text indicates enzymes known to produce 1 for secondary metabolism – i.e., in maize (Fu et al., 2016).
