Gene expression profiles related to the MEP pathway of P. ginseng. (a), the profiles in ginseng roots of 1–5 years old. b, the profiles in different ginseng tissues of 5 years old. 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 expression levels in the MEP pathway of each sample, all the TPM values of the expressed isoforms annotated to that gene of that sample were summarized together. The heatmap was drawn with R package geneplotter and gplots
