Fig. 3. a in Sequencing and variation of terpene synthase gene (TPS2) as the major gene in biosynthesis of thymol in different Thymus species

Fig. 3. a. Maximum likelihood tree of Thymus species based on 16 sequences of the TPS of cDNA. Numbers above branches are support values from bootstrap resembling. Accession numbers of TPS2 sequences obtained from the NCBI GenBank are shown in parentheses (Accession numbers starting with MH were obtained through this study). For the studied species, the main monoterpenes in the essential oil are included T: Thymol; C: Carvacrol; PC: p-Cymene; AT: α-Terpineol; L: Linalool. b. Dendrogram of nine studied Thymus species using Ward clustering method based on Tohidi et al. (2017).
