Fig. 3 in Tissue specificity of (E)-β-farnesene and germacrene D accumulation in pyrethrum flowers

Fig. 3. EβF and GD accumulations in flowers and peduncles at different developmental stages. (A) Semi-quantitative comparison of GD and EβF emitted during different developmental stages (Pre-f, pre-flowering stage; S0-2, flowering plants with dominant S0–S2 flowers; S2-4, flowering plants with dominant S2–S4 flowers; S4-6, flowering plants with dominant S4–S6 flowers). Data are means ± SE of three biological replicates and expressed as peak area. The numbers indicate the ratio of EβF/GD emissions; the asterisks indicate the significance of the differences between EβF and GD (t-test: *, P ≤ 0.05; **, P ≤ 0.01).(B) Emission kinetics of EβF and GD in S0-2 stage T. cinerariifolium flowering plants are shown. The x-axis indicates the sampling time, and the y axis denotes the emission level of EβF and GD. Data are represented as means ± SD (n = 6). Numbers and asterisks are same as in A. (C) GC-MS analysis of the contents of GD and EβF in the T. cinerariifolium flower head at different developmental stages. Numbering of peduncles and flowers followed the developmental stages. Error bars indicate ± SD of three biological replicates. (D) GC-MS analysis of the contents of GD and EβF in T. cinerariifolium peduncles at different developmental stages. Error bars indicate ± SD of three biological replicates.Published as part of Li, Jinjin, Hu, Hao, Chen, Yu, Xie, Jing, Li, Jiawen, Zeng, Tuo, Wang, Manqun, Luo, Jing, Zheng, Riru, Jongsma, Maarten A. & Wang, Caiyun, 2021, Tissue specificity of (E)-β-farnesene and germacrene D accumulation in pyrethrum flowers, pp. 1-11 in Phytochemistry (112768) 187 on page 5, DOI: 10.1016/j.phytochem.2021.112768, http://zenodo.org/record/825894
