Functional identification of PmABCGs in floral scent transport of Prunus mume.

Prunus mume, the only plant in the genus Prunus of the Rosaceae family with a distinctive floral scent, can release a large number of aromatic substances into the air when it blooms. Among these, benzyl acetate has been recognized as a characteristic aromatic substance. In this study, we extracted and analyzed the change in volatility and endogenous content of benzyl acetate using the 'Caizhiwufen' P.

Spatial and Temporal Disparity Analyses of Glycosylated Benzaldehyde and Identification and Expression Pattern Analyses of Uridine Diphosphate Glycosyltransferase Genes in .

The species consists of uniquely aromatic woody perennials with large amounts of free aromatic substances in the flower cells. Uridine diphosphate glycosyltransferase (UGT) modifies these free aromatic substances into water-soluble glycoside-bound volatiles (GBVs) which play an important role in regulating the use of volatiles by plants for information exchange, defense, and stress tolerance. To investigate the changes in the glycosidic state of aromatic substances during the flowering period of and discern the location and expression of glycoside synthesis genes, we extracted and enzymatically hydrolyzed GBVs of and then utilized gas chromatography-mass spectrometry (GC-MS) to characterize and analyze the types and contents of GBV glycosides.
