The expression levels (TPM) of the genes involved in the MEP pathway and the MVA pathway of P. ginseng based on RNA-seq analyses. a, genes in the MEP pathway of the ginseng root samples of 1–5 years old. b, genes in the MVA pathway of the ginseng root samples of 1–5 years old. c, genes in the MEP pathway of different tissues of 5 year-old ginseng. d, genes in the MVA pathway of different tissues of 5 year-old ginseng. R1-R5, ginseng root samples of 1–5 years old. Rc, root cores. Rt, lateral roots. Rh, rhizomes. St, stems, Lf, leaves. DXS, DXR, IspD, IspE, IspF, IspG and IspH, the genes in the MEP pathway. AACT, HMGS, HMGR, MVK, PMK and MVD, the genes in the MVA pathway. For the calculation of each gene transcription levels of each sample, all the TPM values of the expressed isoforms annotated to that gene of that sample were summarized together
