摘要： The spatial distribution and time-course evolution of polyphenol compounds in response to exogenous light and temperature in grape berry (Vitis labruscana cv. 'Kyoho') were examined. Results demonstrated that the poly-phenol biosynthesis was induced via the up-regulated gene transcription levels during berry ripening. The polyphenol biosynthesis was differentially observed in skins, stems, leaves and seeds, and the more polyphenols were accumulated in seeds; and the polyphenols were significantly distributed in bottom berries of grape clusters. Additionally, the lower temperature (4 degrees C) accelerated the polyphenol biosynthesis by 1.3 times after storage of 28 days, whereas the light exposure slightly inhibited the polyphenol biosynthesis of berry during storage at 25 degrees C. In conclusion, the data presented in this study shed more light on deeper understanding of the spatial accumulation and time-course evolution of polyphenols in grape berry.
