Abstract:

This paper reviews the aroma characteristics of Phalaenopsis plants. It focuses on the main components, metabolic synthesis pathways, and regulatory mechanisms related to the fragrance of Phalaenopsis. It summarizes the fragrant varieties of Phalaenopsis, the primary floral scent components, the main factors influencing the release of fragrance in Phalaenopsis, and the molecular regulatory mechanisms related to the metabolic pathways of the major fragrant components. Analysis indicates that terpenoids dominate the floral scent components of Phalaenopsis, with endogenous circadian rhythms, light signals, and temperature all affecting the release rate of floral fragrance. The terpene synthase gene (TPS) and bHLH transcription factors are identified as key genes influencing the metabolic pathways of fragrance components in Phalaenopsis. It has been noted that research on the complete metabolic pathways and molecular regulatory mechanisms of fragrance components in Phalaenopsis is lacking. Future research should focus on further exploring the key genes of fragrance components and supplementing and improving the related metabolic pathways to enhance the understanding of floral fragrance traits in Phalaenopsis.
