Fig. 4 in Volatile metabolic profiling and functional characterization of four terpene synthases reveal terpenoid diversity in different tissues of Chrysanthemum indicum L

Fig. 4. Characterization of CiTPS enzymatic activity. (A) TIC of α-pinene produced in the root of C. indicum, the enzymatic products of CiTPS1 (without an MBP tag), the enzymatic products of CiTPS2 (pET-(-tp)-CiTPS2), and the negative control (GPP + boiled protein). (B) TIC of the corresponding metabolites produced in the root, the enzymatic products of CiTPS3 (without an MBP tag), and the negative control (FPP + boiled protein). (C) TIC of the enzymatic products of CiTPS4 (with GPP and FPP as substrate and without an MBP tag) and the negative control (GPP/FPP + boiled protein). TIC, total ion chromatogram.
