Metabolomic and Transcriptomic Analyses of Flavonoid Biosynthesis in <i>Dendrobium devonianum</i> Flowers.

ABSTRACT:

Background

Dendrobium devonianum is a traditional Chinese medicinal herb with notable ornamental and medicinal value.

Methods

In this study, transcriptomic and metabolomic approaches were employed to investigate gene expression and secondary metabolite changes during four developmental stages of D. devonianum flowers.

Results

Metabolomic analysis identified 1186 distinct metabolites, with flavonoid compounds being the most abundant category (213 types). Transcriptomic analysis revealed 31 differentially expressed genes associated with flavonoid biosynthesis and flavonoid and flavonol biosynthesis pathways. Among these, key genes regulating flavonol synthesis, including F3H (Unigene0077194) and FLS (Unigene0062137), exhibited high expression
