Differential expression of the unigenes related to the taxol biosynthesis pathway. a Overview of the taxol biosynthesis pathway. b Enrichment analysis of six taxol biosynthesis-related GO terms. The significant P values of each GO term in the three comparisons were shown by a heatmap. c Expression analysis of the unigenes related to the taxol biosynthesis pathway. Enzymes abbreviations are: DXS: 1-Deoxy-D-xylulose 5-phosphate synthase; DXR: 1-Deoxy-D-xylulose 5-phosphate reductoisomerase; 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; HDS: 4-Hydroxy-3-methylbut-2-enyl-diphosphate synthase; HDR: 4-Hydroxy-3-methylbut-2-enyl diphosphate reductase; IPPI: isopentenyl diphosphate isomerase; GGPPS: geranylgeranyl diphosphate synthase; TS, taxadiene synthase; T13OH: taxoid 13-α-hydroxylase; T10OH: taxoid 10-β-hydroxylase; T14OH: Taxoid 14-β-hydroxylase; T7OH: taxoid-7β-hydroxylase; T2OH: taxoid-2α-hydroxylase; T5OH: taxadiene-5α-hydroxylase; DBAT: 10-deacetylbaccatin III-10-β-O-acetyltransferase; PAL: phenylalanine aminomutase; Benzoyl CoA: 2-debenzoyl-7,13-diacetylbaccatin III-2-O-benzoyl transferase.
