Abstract:

The floral scent of Prunus mume is mainly composed of benzenoid and phenylpropanoid volatile organic compounds. The biosynthesis and emission of floral scent in P. mume exhibit pronounced spatial and temporal specificity and are also influenced by multiple factors,including light,temperature,and exogenous regulators. This review summarizes recent advances in research on P. mume floral scent,with a focus on the major scent components and their biosynthetic pathways,molecular regulatory mechanisms,and emission patterns. Future research directions are also discussed,with the aim of providing references for elucidating the formation mechanisms of floral scent traits in P. mume and for guiding the efficient breeding of new cultivars with novel fragrance characteristics.

Key words: Prunus mume, floral fragrance, biosynthesis, molecular mechanism
