Identification of candidate transcription factors regulating terpenoids. Phylogenetic tree inferred from the amino sequences of the TFs regulating terpenoids in other species with their close relatives in C. goeringii. Various types of TFs were shown: bHLH (a), bZIP (b), ERF (c), MYB (d), NAC (e), WRKY (f). The phylogenetic tree was constructed either with the maximum-likelihood (a, b, c, e, f) or neighbor-joining method (d). Bootstrap values were calculated as a percentage of 1000 replicates. The closest candidate TFs with the TFs regulating terpenoids were shown in bold. g Expression levels of the candidate TFs shown in bold in (a) to (f). The candidate TFs classified into STEM profile ID 2 and 3 were labeled with an open circle and a dark dot, respectively
