Relative expression of genes involved in tanshinone biosynthesis in transgenic hairy roots of Salvia miltiorrhiza. WT, wild type; p35S::SmMDS-11, p35S::SmMDS transgenic line 11; p35S::SmMDS-16, p35S::SmMDS transgenic line 16. Values are presented as mean ± SD, n = 3. The y-axis shows the normalized gene expression after log2 transformation. MCT, 2-c-methyl-d-erythritol 4-phosphate cytidylyltransferase; CMK, 4-(cytidine 5′-diphospho)-2-c-methyl-d-erythritol kinase; MDS, 2-c-methyl-d-erythritol 2,4-cyclodiphosphate synthase; HDR, 4-hydroxy-3-methylbut-2-enyl diphosphate reductase; HMGR, hydroxymethylglutaryl-CoA reductase; PMK, 5-phosphomevalonate kinase; IDI, isopentenyl diphosphate isomerase; CPS, copalyl diphosphate synthase; KSL, kaurene synthase-like
