Untargeted metabolomics and functional analyses reveal that the secondary metabolite quinic acid associates with Angelica sinensis flowering.

ABSTRACT: Flowering is a critical step in the plant life cycle. Angelica sinensis (Oliv.) Diels is a medicinal crop whose root is a well-known herbal medicine used in Asia. Early flowering causes changes in secondary metabolic flow and results in the loss of medicinal quality. Based on untargeted metabolomics studies, quinic acid was identified as a metabolite present in significantly higher concentrations during the early-flowering stage in A. sinensis leaves. This metabolite was subsequently investigated as a potential marker for early bolting in A. sinensis under field conditions. Moreover, quinic acid was found to accelerate flowering in the model plant Arabidopsis thaliana. Importantly, the flowering time was delayed in the quinate dehydrogenase At mutant, and this delay was reversed by quinic
