Fig 4. Overview of the triterpenoid biosynthetic pathway.

Fig 4

For each gene, the top row of squares represents the Control and the bottom row represents the NAA and 6-BA treatment. The number of squares indicates the number of differentially expressed genes with fold changes ≥ 2 or fold change ≤ 0.5 at adjusted P < 0.05. Different colors indicate genes that were down-regulated (green) or up-regulated (red) in the T group compared with the Control group. Abbreviations are as follows: AACT, acetyl-CoA acetyltransferase; MK, mevalonate kinase; DXR, 1-deoxy-D-xylulose5-phosphate reductoisomerase; CMK, 4-(cytidine-diphospho)-2-C-methyl-D-erythritol kinase; MCS, 2-C-methyl-D-erythritol-2,4- cyclodiphosphate synthase; GPPS, geranyl diphosphate synthase; GGPPS, geranylgeranyl diphosphate synthase; DDS, dammarenediol synthase; LS, lanosterol synthase; LUS, lupeol synthesis; and UGT, UDP-glycosyltransferase.
