| description | Dendrobium officinale Kimura et Migo is a tonic plant that has both ornamental and medicinal properties. Terpenoids are significant and diverse secondary metabolites in plants, and are one of the important natural active ingredients in D. officinale. The AP2/ERF gene family plays a major role in primary and secondary metabolism. However, the AP2/ERF transcription factor family has not been identified in D. officinale, and it is unclear if it is involved in the regulation of terpenoid biosynthesis. This study identified a sesquiterpene synthetase-β-patchoulene synthase (DoPAES) using transcriptome and terpenic metabolic profile analyses. A total of 111 members of the AP2/ERF family were identified through the whole genome of D. officinale. The tissue-specific expression and gene co-expression pattern of the DoAP2/ERF family members were analyzed. The results showed that the expression of DoPAES was highly correlated with the expression of DoAP2/ERF89 and DoAP2/ERF47. The yeast one-hybrid (Y1H) assays and dual-luciferase experiments demonstrated that DoAP2/ERF89 and DoAP2/ERF47 could regulate the expression of DoPAES. The transcriptional regulatory effects were examined using homologous transient expression of DoAP2/ERF89 in protocorms of D. officinale. DoAP2/ERF89 positively regulated the biosynthesis of β-patchoulene. This study showed that DoAP2/ERF89 can bind to the promoter region of DoPAES to control its expression and further regulate the biosynthesis of β-patchoulene in D. officinale. These results provide new insights on the regulation of terpenoid biosynthesis. |
