Background: Flavonoids with various structures play a vital role in plant acclimatization to varying environments as well as in plant growth, development, and reproduction. Exogenous applications of ethylene and 1-aminocyclopropane carboxylic acid (ACC), could affect the accumulation of flavonoids. Very few attempts have been made to investigate the effect of 1-aminocyclopropane carboxylic acid oxidase (ACO), a unique enzyme that catalyzes ACC to ethylene, on genes and metabolites in the flavonoid biosynthetic pathway.

- Flavonoids are important secondary metabolites in safflower, contributing to plant growth and human health, yet research on the biosynthetic genes, particularly for quinochalcones, is limited.
- A gene called CtF3H was isolated and confirmed to relate to flavonoid production, showing high similarity to F3H genes in other plants and was found in both the nucleus and cytosol of cells.
- Transcriptome analysis revealed differing expression patterns of CtF3H between two safflower types under methyl jasmonate treatment, with an increase in specific flavonoids in quinochalcone-type safflower and different accumulation patterns in flavonol-type safflower.
Ethnopharmacological Relevance: Callicarpa L. (Verbenaceae) has been used for centuries in Traditional Chinese Medicine (TCM) for the prevention and treatment of a wide number of health disorders such as inflammation, rheumatism, hematuria, fracture, hematemesis, menoxenia, gastrointestinal bleeding, scrofula, etc.
Aims Of The Review: To assess the scientific evidence for therapeutic Callicarpa in TCM and to identify future research needs.
