Transcriptomic analysis revealed the mechanisms involved in the differential accumulation of taxoids, flavonoids and hormones among three Taxaceae trees


ABSTRACT: The natural product taxol is an efficient and worldwide accepted anticancer drug. Taxol and other taxoids accumulate in only a few specific genera of the Taxaceae family, such as Taxus and Pseudotaxus. The comprehensive variations among three Taxaceae trees, including one taxol-producing (TP) and two non-taxol producing (NTP) trees, were compared. In total, 3,655 metabolites and 88,609 functional genes were identified through metabolomic and transcriptomic analyses, respectively. KEGG enrichment analysis showed that many differentially expressed genes were enriched in several hormone-, flavonoid-, and terpenoid-related metabolic pathways. The hormones, abscisate and abscisic acid, highly accumulated in the NTP trees, whereas gibberellic acids substantially accumulated in the TP trees.
