Liu C.C., and Li Z.G., 2025, Molecular regulation of durian fruit aroma: genetic network of sulfur-containing volatile biosynthesis, International Journal of Horticulture, 15(4): 185-194 (doi: 10.5376/ijh.2025.15.0019)

This study describes the molecular regulatory mechanism of aroma formation in durian (Durio zibethinus) fruit and explores the biosynthetic pathway of sulfur-containing volatiles and their genetic network. The key role of sulfur-containing compounds in imparting a unique odor to the fruit, the core gene family involved in aroma biosynthesis, and the functions of transcription factors (such as MYB and bHLH) in the regulatory network, constructed a regulatory network model reflecting complex interactions. This study also explored the effects of environmental factors such as temperature and light and the fruit development stage on the changes in aroma components, and the mechanism of synergistic effects of external signals and internal regulatory factors. Emerging technologies such as molecular breeding, gene editing, and systems biology have important application prospects for improving the aroma quality of durian.
